Does someone knows how to build the bahamut lagoon translation source code?

>>7906287
Does anyone have the rom for this game?

Hyper Metroid graphics seem to have been made in mind for a LCD monitor with a gamma of 2.2
It is very dark on a real CRT and you have to increase brightness.

do they sell physical copies of ROM hacks in stores in places like Hong Kong?

>>7906293
What would the gameplay be like?

>>7907865
My first contact with internet-made hacks was when I got a chinese cart with Spider-Man 2, so, I guess a few?
Not sure if they still make those nowadays, though.

Someone use Xeno GC here ?

is there an ff6 romhack that is the jp version translated?

Is there still a list of recent dumped and undumped games?

Why haven't you started a disassembly of your favorite game, anon?

I've been wanting to do this hack for a while

Game: Super Street Fighter II X For Matching Service
Platform: Dreamcast
Language: Japanese

Goals
-English translation of all menus, names, and win quotes
>removal of matching service and online features from main menu
-Replacement of voice samples to match USA release aka Super Turbo. Example: change Dee Jay's "Slash!" to "Max Out!"
>customize stage and character palettes to match the Super Street Fighter II palette
>replace audio with arranged soundtrack from one of the other releases of the game
>add 240p mode option which should be attainable using code borrowed from the Dreamcast Third Strike release which has this mode.

What do you think of this idea?

>>7910586

No. There was no point doing that once some kid on the internet announced that the full set he downloaded from emuparadise had everything.

There's lots of stuff in this hack that I wish were stand-alone patches, or available in those SMB editors. Mainly the Hammer suit.

https://www.retroreversing.com/official-playStation-devkit

>>7913240
What would be a good system for organizing stand-alone patches? It would have to be a bit “smart” wouldn’t it? Or rely on an assembler to automatically organize code and labels.

>>7914776
Uh
I don't get what you mean, I just usually download patches from romhacking.

>>7914998
> stand-alone patch
he means patches that can be combined together. unfortunately there is no such thing: if two patches change the same part of the game to achieve two different results it's game over. there's no "automated patch collision tester" as far as i know, you'd have to conduct that work by hand, or you know, just try it and see if the game breaks.
> It would have to be a bit “smart” wouldn’t it?
yeah. that would be an interesting and fairly difficult problem to solve. IPS' are generally unaware of the format of a game: they just change the right bytes compared to an exact copy of the original. patches that would work together change small parts of the game without rearranging the larger structure of it.
> Or rely on an assembler to automatically organize code and labels.
I suppose something like this could be built, but, it's hard for a disassembler to know what is code and what isn't. instructions and data look the same as far as it knows. emulator debuggers solve this by acutally running the code and making educated guesses about what's what.
SMB is a special case though, because a full disassembly exists, unlike most games. if two patches used this to change the overarching structure of the game, combining two IPS patches just wouldn't work. it might be possible to build some disassembler / DIF analyzer that pieces together similar parts of the game and finds what you're trying to change from each patch, but, that would be a project and a half. good luck.
TL;DR it might be possible kinda in some situations but it would be very difficult to organize / build something that does this automatically.

>>7915230
I meant like how some SMB graphic improvement patches are compatible with the 2 player co-op patch for instance, yes. Or how some Mega Man patches, like selecting weapons with Select, or the Slide and Charged Shot patch for MM2 can be used with others.

>>7915304
Right, it means they didn't touch the overarching structure of the game and changed two unrelated parts. It's not something you can guarantee though: Patch A might work with Patch B or Patch C, but patch B and C may be incompatible. Patch D might work with Patch B or Patch C but Patch A and D might be incompatible.
All i'm trying to say is you can't guarantee something is a "stand alone patch" because they all change something.

>>7915346
Oh yeah I know, but it's better than nothing. You could see what's compatible, or even start patching those, and then reworking the graphics manually from there.

>>7915346
>>7915372
As opposed to going with the whole Tower RE package.

>>7906293
Corpse Party 64

>>7915372
Right, you'd have to do it by hand on a patch by patch basis and essentially build a compatibility matrix. Which brings us back to:
> What would be a good system for organizing stand-alone patches?
Unfortunately there isn't =(
It would be a very difficult problem to solve with any sort of universality.

>>7915448
Hm, maybe a symbol of incompatibility on less sociable patches?

>>7906287
Are translations allowed here or are they a separate thing?

>>7915525
Why not?

>>7915525
Translations are romhacks: It's not just converting text. The code has to be altered to accommodate new / different text and graphics.

>>7915230
I think it could be done if the patches follow a predictable structure. Patch 1, overwrite 10 byes, 2 bytes being a label resolved at linker stage, reference data or code in a clean expanded memory bank.

If an assembler had the functionality of overwriting an existing rom it would be easy. Like in a ca65 linker script, instead of setting FILL to a byte value, being able to set it to a ROM file.

>>7906287
Here's how to build the byuu's bahamut lagoon translation source code
https://pastebin.com/ENAk4akc

>>7916120
As long as the main structure isn't touched it could be done. Most romhacks just change a few things here and there, or add subroutines pointing to unused spaces in the ROM. That is all well and good and perhaps adaptable with automation.
Where you run into trouble is if the game was reassembled and data / branches / jumps were shifted or moved around. You (maybe) could regenerate two linking structures with each file and somehow match them up. You'd run into Real Trouble if you ran out of space or you had to combine the patches in such a way that branches no longer fell within the -128 / 127 byte range.
For most cases i think your plan would work: I don't know if anyone has tried to make a disassembler / linker. Sounds like a fun project.

>>7906293
Darkstalkers (SNES)

>>7916120
This exists for SMW, in a few different ways. There's GPS for adding new blocks. PIXI (or spritetool or something) for adding new sprites. UberASM for adding level/mode dependent code.

You do have to write your asm in specific ways, and some of the publicly available code can--and does--stomp on each other's toes, but it works surprisingly well.

There's no reason, aside from maybe rom/ram space constraints, that SMB1 couldn't have similar tooling. You'd just need to build it.

>>7910586
I took the first step which is checking to see if the game has ADX audio. ADX is the format which enables easy hacking of Dreamcast music tracks. The ADX logo is visible on the back of the GD-ROM case.

>>7906293
Darkstalkers all the niggas edition, like the PS2 version has, but on CPS2

>>7916672
If you have a disassembly and the romhacks are code snippets instead of byte replacement, it is way easier to combine hacks and many more things are on the table. This isn't the case for the majority of games though unfortunately. >>7910506

>>7916725
Nah, better on SNES system.

>>7916672
>SMB1 (could) have similar tooling. You'd just need to build it.
There are full level editors with ROM expanders like SMButil. SMB has been converted to different mappers for hacks before. Armed with the disassembly many things are possible. It just doesn't have the community / interest that SMW has.

>>7916787
make it Famiclone

While we're at it, I heard the SMB2 randomizer inserts new power-ups into the game. I couldn't run it, but new power-ups always sound like great for new patches.

>>7919598
>>7919614
You're both retarded. I downloaded MMX1 from the other website and compared the Intro Stage rip to the rip from Zophar. Besides the header and footer metadata that was added, which means that two different people ripped them, they are COMPLETELY 100% IDENTICAL.
so uh yeah. nice try. should i compare more of them? i don't really want to and i have other shit to do, so uh, yeah. are you happy now?

>>7919660
holy goddamn, you are retarded. I said it's possible, not that it was. zophar was a source of some bad rips back in the day, be it data errors or as your screenshot showcases so well: mistagged. so I will never trust it today even if they fixed their shit up, nevermind the fact that they've always had a wildly incomplete archive

>>7919685
>mistagged
hmmmm i didn't even think about that. come to think of it, some of the metadata from the Zophar rips is a bit fucky. i was just thinking about the samples and the songs themselves, but, you bring up a valid point.
i do like the search and grouping functionality at Zophar though, like, if i find an OST i like i'll click on the developer or publisher and rifle through those. the previews are nice as well; i can listen for a few seconds and decide if the OST is worth downloading. it's harder and harder to find new good stuff once you have tens of thousands of files and most of the major companies checked off the list.

>>7919725
I will admit that those are indeed good features to have over joshw.info's barebones file system.

>>7919731
i guess i was a little too defensive of Zophar's rips considering i already have tens of thousands of them.
SNES is less of a concern because the APU handles so much of it, but, with systems like the NES / genesis where the main processor and it's code are controlling the audio chip bad / inaccurate rips are more likely to occur.

>>7917330
>I'm asking for a romhack that would actually be the best version of the game
Which would be SNES.

>>7919846
>>7918403
It can be done, probably 128k ROM is good enough since there's really only three distinct levels/tile sets. The levels would have to be shortened/broken down into manageable pieces to fit in the NES's memory space. You couldn't do it at the same framerate as the PC especially as there's diagonal scrolling.

>>7919914
https://nesmaps.com/maps/Castlevania/CastlevaniaCompleteMapB.html

You'd be surprised how short the levels are here since when playing (or when you were a kid) they seem immense and endless. It's not as if you have a huge amount of room in 40k memory space.

>>7919745
>but, with systems like the NES / genesis where the main processor and it's code are controlling the audio chip
The Mega Drive has a separate Z80 to drive the audio chip. Though you could use the main CPU to drive it if you want to.

I beat Hyper Metroid.
I loaded one save state during the escape because I died and I didn't want to fight mother brain and escape Tourian again.
Maybe I'll go back and do the whole escape from scratch again to say I beat the whole thing without a single save state but I'm too enthusiastic to do that.
Clear time was 07:36 with 73% items collected.

It was a good game but is too long and too open. I think Redesign is better.

>I liked redesign better
Why exactly? I think them crippling wall jumping was too much, felt like an autist that was rump-ravaged at the sandbox-y nature of Samus' controls and physics and wanted to make sure it was only autist-approved fun.
The heavier jumps were satisfying, I won't deny that.

>>7920131
which anime are you from

>>7920139

>>7920138
It took me about 20 minutes to get out of the first pit after you get the wall jump boots, but after that I had no issue wall jumping anywhere else in the hack. The timing is more delayed from original Super Metroid but once you've got it you've got it.
I enjoyed the different physics because it reminded me that Redesign is a new game. Hyper Metroid has different physics too.

I beat Redesign not long after it came out on a modded Xbox and used some save states, particularly in the escape sequence of that game too. And the grappling hook room in Norfair. But a few years later I went back and beat it on a flash cart with any save states at all.
Then I sold my flash cart to buy a new computer.

>>7920146
I was more pissed that walljumping is only allowed on certain services and you MUST have two walls in order to climb.

>>7920131
Well you got me to replay it and I just completed the escape in a single segment from the start. I didn't re-beat Mother Brain but that battle is very easy so I didn't bother.
In the rest of the game pre-escape I didn't use any save states at all. I set a few but ended up not using them.

>>7920186
I was just Joshing you man but good job anyway.

>>7920189
I do feel better about it and tomorrow I'll probably go back and do a single segment from the last Tourian save beating Mother Brain again to say that I beat it just like a real cart (other than the practice I had from the earlier runs).

>>7919923
>It's not as if you have a huge amount of room in 40k memory space
Castlevania is 128k ROM though?

>>7921380
it's kind of nice to not have it in the gameplay. i assume they were just showing off the SNES layering / transparency abilities but the placement is very unfortunate.
say i were to move it, what would be a good solution? it might be possible to toggle / disable the other HUD elements and stick it more to the top out of the way.
i don't think the Genesis solution is very good either: a real CRT would probably cut alot of that off as it's not in the NTSC safe area at all. genereally you need things within 16x16 pixels away from the edges to be visible. ...maybe the Genesis doesn't have to worry about that though? i'm not all that familiar with using it on a Legit setup, though i do have one and very recently a flashcart.

>>7921385
you'd be surprised how much you can fit in 32K of code with properly written assembly language. that game could probably be done.

>>7921385
Yes but the NES can only see 40k of ROM at a time. Imagine NES ROMs as being a collection of 40k sized programs you link together and select which one is currently active. As a consequence game levels are naturally going to be pretty short compared to what they are on 16-bit consoles.

>>7921551
> Yes but the NES can only see 40k of ROM
32k of ROM. the other 8k is CHR. you can't mix and match.

it's kind of like on the Atari 2600 where the ROM space is 4k and if you had a 16k game like Dig Dug or Solaris, the game is basically four 4k programs that you switch between.

>>7921604
>the game is basically four 4k programs that you switch between.
welllllllll yes and no. bank switching is instantons. lots of times there was a main part of the program that stayed in memory / was repeated in each bank and the banks contained data for different levels / music / animations / what have you.

>>7919891
Shut up, you fucking retard.
>>7919086
Fucking huh? Even the first Darkstalkers game is larger than SFA2 and is way more ambitious regarding sprite size, frames in memory, speed, and sprites on screen. Fuck off tards.

>>7921630
>instantons
instantaneous LUL

>>7921508
i honestly never minded the map placement. it's not too in the way and it's transparent. i also didn't keep it open, just a quick toggle usually to see if anyone's near.

>>7921630
Banking on the 2600 wasn't that sophisticated, it was literally just switching between each 4k block of the ROM.

>>7921795
yeah true. on the NES normally you would switch banks in 16k pieces and some more advanced mappers let you switch in 8k pieces. but usually you have one fixed bank that contains core game routines as well as the banking code. there are other exception, LOZ for example copies some core routines to the PRG RAM so they can be accessed no matter what bank is active.

I feel bad using savestates on regular games, but not on romhacks, why is that?

>>7921551
16-bit consoles work in a somewhat similar way but there's no banks and thus no limit on how much code/graphics/sound can be used except the total ROM size.

>>7919914
60 fps is generally only achievable on the NES if you're scrolling in one axis in the direction of the mirroring. Thus SMB has no issue with 60 fps because it's set to vertical mirroring and only ever scrolls horizontally. SMB3 has 8 directional scrolling so it can't run at 60 fps, a lower framerate is necessary.

>>7922041
ROMhacks are often made by amateurs that have a poor grasp on balance.

>>7922041
some romhacks are much more difficult and redesigned levels aren't made by professionals: i've been through a softlock or three in my time. with a published game you know it's beatable and not broken in all but the worst cases.
it's amazing though being able to relive games like Super Metroid and Mario 3 like it's the first time through again.

>>7922190
sometimes a lower framerate was deliberately used to avoid slowdown or dot crawl. for example Zelda II does this.

>>7922041
Some rom hacks are made with the idea the player will be using them.

>>7922190
SMB3 runs perfectly at 60FPS. What are you talking about?

>>7922190
Furthermore scrolling is absolutely free. You just write a pair of coordinates to the scroll register. That's it. Loading level data in four directions to the name/attr tables takes a bit more time, but, it's not significant compared to keeping track of objects. What takes up most of the horsepower is calculating a bunch of sprite positions and object hitboxes.

>>7922320
It's almost free if scrolling in the direction of the mirroring as you can move one complete screen before updating the tile map, if not in the direction of the mirroring it's slightly slower as each row has to be updated and there are graphics glitches at the edge of the screen.

>>7921820
>copies some core routines to the PRG RAM
you can also use that for some timing critical code, like preparing an unrolled loop to copy values to the CHR RAM at vblank

>>7922320
scrolling is a pain because you have to account for the attribute table

>>7921820
>but usually you have one fixed bank that contains core game routines as well as the banking code
Typically you have to include redundant copies of this code in multiple banks because ASIC mappers will just put any random bank in $C000-$FFFF at power on.

https://www.youtube.com/watch?v=5NWByyxT9ak

say in Renegade it manages the high speed scrolling in the motorcycle chase sections because the game uses V mirroring.

https://www.youtube.com/watch?v=VMJXZm21faY

Double Dragon is MMC1 but normally stays in H mirroring mode while scrolling horizontally so the scrolling is a bit less smooth and of course has graphics glitches.

>>7921820
>and some more advanced mappers let you switch in 8k pieces.
this is important in Kirby's Adventure btw, when you get a power up it switches in the object code for it

>>7922356
>there are graphics glitches at the edge of the screen.
Yeah, it's unfortunate. You're basically stuck with horizontal mirroring and vertical scrolling without mapper help if you want 4 directional scrolling.
Somari, of all things, actually avoids the graphical glitches by just chopping off the bottom 16 pixels. You could also have extended RAM in the cart fill out all 4 name/attr tables.

>>7921365
Here's the version for old emulators like zsnes for example if it doesn't work
https://files.catbox.moe/ql558u.sfc
For some reason, they made 2 versions, one for emulators and one for real hardware/accurate emulators

>>7920190
I went back and beat it from the Tourian save.

>>7922420
>You're basically stuck with horizontal mirroring and vertical scrolling without mapper help if you want 4 directional scrolling

Some games like Zelda switch the mirroring as needed, depending on what direction the screen is moving in. This is usually when you have an open game map where you're moving in any direction Others like Double Dragon mostly just scroll horizontally with sections where they have to move the screen vertically so H mirroring is used the whole time to make the vertical scroll easier--in these kind of games action pauses during vertical scrolling.

SMB3 and Kirby have 8-way scrolling so they also just stay in H mirroring the whole time.

there's also single screen mirroring which some mappers support; for example Rare's AxROM cartridges. MMC1 also has an option for this, which MMC3 unfortunately got rid of.

>>7922475
True. Right i meant "8 direction" or 2 directions simultaneously.
Metroid is an elegant example of this, it switches the mirroring direction every door entry, and stacks the nametable addresses in such a way that it always works.

>>7922514
>mirroring direction
mirroring orientation rather. horizontal or vertical isn't really a direction.

>>7922514
think Dragon Quest where mirroring is switched on the fly--in the NES conversions which used MMC1. The Famicom DQ1 and 2 were UNROM and set to vertical mirroring so the graphics produce glitches when moving up and down.

>>7922475
Double Dragon seems as if it could have gotten away with UNROM, I'm not sure exactly why MMC1 was needed there.

>>7922537
the game has 256k of ROM and UNROM only supported 128k, no?

>>7922542
Granted, there was a version of UNROM that supported 256k but it wasn't used much and may have not been available yet when DD came out. However if you needed more than 128k of ROM it was considered better to just use an ASIC mapper.

>>7922537
> I don't know why X used advanced mapper Y when they could have gotten away with basic mapper Z
I see this post alot. Much of mapper choice has to do with what chips were in stock or being produced at the time. It's not just a technical question but a logical one: you had to physically make tens / hundreds of thousands of these things. Later games that were basic with unused mapper features couldn't just go back to basic mappers of the past that weren't being manufactured anymore because, well, they were not being manufactured anymore.

>>7922632

Let's say I wanted to put up some money, like 100 for a bounty on a mod I want. How would I do that? See the Japanese version of Blue Stinger had fixed camera angles like classic RE, the western version had a behind the shoulder camera added and it's awful. If love the English dialog and text with the Japanese camera angles. Not sure how hard that would be

>>7922647
>Not sure how hard that would be
You really wouldn't know unless you tried it. It might be as simple as flipping the "japanese camera" bit. You might have to reengineer the entire fucking game. It's impossible to know until you get your hands dirty.
You could start by running both games in an emulator and looking for different bits that are consistent. You might get lucky.

Double Dragon was an early MMC1 game from 88 and discreet mappers like UxROM just use a TTL to switch the ROM banks, there's no custom silicon. most likely they needed to support 256k ROM and standard UxROM only supports 128k. there's also feature creep, if a developer wasn't exactly sure what they needed it was often better to play it safe and not use a more limiting cartridge setup.

ASIC mappers were generally preferred for their greater flexibility. usually budget games would have discreet mappers to reduce costs.

>>7922801
yeah a lot of Capcom Disney games used them. it seemed Capcom were cheaper than Konami because the latter's licensed NES titles were seemingly always MMC3 with big ROMs.

The Famicom was originally only meant to scroll in one axis and you could choose which one depending on how the cartridge PCB was wired. Scrolling in the non-mirrored axis is basically a hack. Then later of course ASIC mappers let you select the mirroring direction via software.

>>7924296
> oot decomp is FUCKING HAPPENING
indeed it is; and has been for a minute or two.
any new updates / milestones?

>>7924320
>Scrolling in the non-mirrored axis is basically a hack.
I'm not so sure. The scroll register is built to handle both X and Y coordinates. Being that the PCB seemed to be designed for 4 nametables with an unpopulated slot (and data lines to handle it in the cartridge) it makes me think scrolling in X/Y directions simultaneously was absolutely considered in the original design; even if it wasn't done with the early games.

The NES's mirrored nametables are an inefficient setup; the Master System and Gameboy, both designed later with the benefit of accumulated knowledge, don't mirror an entire table.

>>7924424
> designed later with the benefit of accumulated knowledge
i think cheaper RAM prices had wayyy more to do with it. an extra 2KB was a pretty penny in 1983 for a mass produced toy computer. the Fami / NES was in fact designed to handle 4 nametables: you just have to have extra RAM in the cart unfortunately.

>>7924473
Or even just disable the mirroring altogether and have a Master System-like setup.

>>7924562
> just disable the mirroring
It's honestly not a bad idea. Use one nametable for the playfield and another for the status bar. Rare did all kinds of awesome shit with this setup.

Sea Chase SFX are all in place. I used an old sound register testing ROM that i modernized a year ago to design them. It was fun writing a custom sound engine. One more thing off the bucket list =)
I have the title screen song laid out in Famtracker, it's just a question of converting it to my custom sound engine now. The final product should sound identical(ish) but take up Much less space. This involves keying in all of the hex by hand. Should be a fun fun time...
Anyway, the damn thing is almost done! Hoping to release it next week or so. It's been 3 months, about a month longer than i thought it would take worst case, but doesn't everything always. I'm excited about how it turned out and equally excited to move on with my life at this point.
I'm pretty happy with the title screen song. It's very faithful to the original and yet has a bit more flare:

the NES has a bit more sophisticated sound capabilities than the Atari 8-bit

>>7927478
yes indeed it does and i assure you i made good use of it =)
one of the things that frustrates me w/ Famitracker is that it doesn't use alot of the APU built in functionality. To be fair, it is very confusing and awkward to use. i would have been lost without the register testing program.
0CC Famitracker addresses this somewhat but it's still limited compared to the true power of the built in APU functions.

yes when you consider what Tim Follins did in Silver Surfer with crude 1980s tools

It's been a while since I posted some N64 stuff, so here goes:

There's now a text-rendering system, complete with unicode support. It's a little unoptimized, but the core functionality is there.

More importantly, the material system has been expanded to include many N64-specific settings. You can now, for example, set custom combiner equations, mess with the render mode, and even do multi-texturing. This makes it possible to hit the hardware more directly and really take advantage of the RDP's "powerful" capabilities.

And that's about it for now.

>>7929143
Rare's AxROM setup was single screen with soft selectable mirroring direction. Though it didn't provide any IRQs so you still had to use sprite 0 hit for status bars.

>>7930974
scanline IRQs make split scrolling easier since it provides a more stable screen split than polling for sprite 0 hit

>>7931329
true, not only that, scanline IRQ is an interrupt so you don't have to stop everything you're doing in code and poll $2002 in a loop. it's nice to not have to design your entire game loop around the screen split.

>>7930974
Didn't they just have it so the whole 32k PRG is switched all at once?

>>7931404
Yes. It creates some issues with redundant code in each bank which wastes space and making it a bit trickier to use DCPM samples.

>>7931329
It depends somewhat on how the code loop is constructed but certain games like TMNT are very prone to the status bar breaking up when there's too much happening on screen.

this might not be the thread to ask, but I can't find anything related in the catalog. What's the best place to get NDS roms/emulators?

Just a dumbass question but I figure you guys would know.
SNES can only rotate/scale backgrounds in Mode 7. Mode 7 also supports only one background.
What's going on in these cutscenes? This one is from the intro, but there are others at the end of the game. The ship is rotated/scaled but there seems to be additional background layers behind it.

>>7931981
I'm pretty sure everything is on the sprite layer in these scenes. That's how some of the boss rooms are handled in Mario World, too.

>>7931981
The ship is clearly mode 7. The stars appear to be one background layer, and the asteroids and the space station are probably sprites. This is just a guess: You could look in Snes9x or your favorite emulator and start enabling / disabling background layers to confirm this or tell me i'm full of shit =)

>>7931981
You were right >>7932030
Turns out the stars / space station / asteroids are all sprites. The ship and "SPACE COLONY" text is on mode 7 BG1.

>>7931791
>Because Gradius puts its status bar at the bottom, it can't just spin on sprite 0 all the time. Instead, it counts the approximate time that each object handler takes and deliberately delays the remaining calculations to the next frame when it might otherwise come close to missing a sprite 0 hit.

Note that TMNT has the status bar on the bottom not the top which complicates your coding a bit.

>>7932073
>>7932030
Cheers anon!

Yup, the SNES can handle a full screen of sprites (about 280 sprite pixels per line) which is good for acting like another layer for things like mode 7 or graphics importing chips.
But that's best for stuff like display screens or cut scenes since that leaves very few sprites for objects on top of it, and there's some GPU bug that makes sprite exchange flickering near useless.

>>7932297
Also changing only the X scroll value is an eas(ier) operation with lots of leway comparted to the changing the Y value or both of them. It's one of the few things the PPU can tolerate well.

Is there any group that archives romhacks into a .dat file?

>>7933864
Check the copypasta for several romhack archives. If you know of anymore i'll include them next thread.
>.dat file
I don't even know what that is?

>>7933873
Rom managers use .dat files to match file hashes and identify files. They're used by a lot of groups like No-Intro, the MAME team, or the Total DOS Collection guys to validate roms. It makes it so you can turn a ROM manager loose on a folder and automatically locate any roms in a set.

A group called Retroplay has started doing translation patches, so they can distribute full validated sets of up to date prepatched roms. I'd like to have something similar for gameplay patches, but I don't want to embark on some big project if something like that already exists.

Were I to do it myself I'd ideally want to compile seperate registries for the prepatched roms, the patch contents, and the proper associated unpatched rom.

>>7933908
i see so you're looking for a system of hash validated prepatched romhacks? i don't think such a thing exists to my knowledge.
romhacking.net does validate which ROM you need to use before you upload a hack though, and you as the patcher can verify that, it's up to you though to patch it from there.

Simple request. How about a hack for Eliminate Down where pressing the A button cycles Hough your weapons backwards. I never understood why both A and C just did the same thing.

>>7933852
>Also changing only the X scroll value is an eas(ier) operation with lots of leway comparted to the changing the Y value or both of them

>with all the rumored stuff, like Pokegods, Mew under the truck, the Mist Stone, etc

>>7933969
> there's no difference in X or Y scrolling on the NES
Ohhhhhh yes there is. You can just write to the scroll registers in vBlank to denote a new position, but, if you change values mid-frame it gets a whole lot messier.
Changing the X value mid frame is pretty easy: you just write a new X value to the scroll register ($2005), and it just werks. Plenty of time to do it. Changing Y or both X/Y is much more complicated.
The PPU uses the ADDR ($2006) values to render the nametable, and keeps / increments the nametable value there. so, in order to change the Y value, you have to write the "top left of the nametable" value into $2006 and it will start rendering from the scanline you're at. You can't just write to the scroll register mid-frame: it doesn't compensate for the new nametable value, unlike in vBlank.
However: you can't just write in the new nametable value either. There are fine X and fine Y registers that actually exist in the PPU, each denoting 0-7 pixels from the offset of the nametable values. You end up with a combination of $2006, $2005, $2005, $2006 writes in this specific order so you get the X/Y scroll values you want where you want them. It's messy and extremely time sensitive. This isn't even getting into the various (sometimes documented) hardware bugs that fuck up your sprites / palettes when you fuck with the PPU mid-frame. That is a whole 'nother bucket of fun =)
https://wiki.nesdev.com/w/index.php/PPU_scrolling#Summary

>>7934069
I forgot to mention that all of these mid-frame PPU writes have to take place in hBlank (between scanline draws) and sometimes a specific piece of the already difficult to syncronize hBlank to avoid hardware sprite flickering / palette dropping issues that occur on hardware: they aren't emulated and aren't even completely understood yet =)

>>7934069
https://www.youtube.com/watch?v=qwfc5-sgllk

is that with a status bar or without because there are plenty of V scroll games like B-Wings with no status bar and this even has a little bit of diagonal scrolling.

Commando is one of the worst examples. It was the first NES game Capcom developed in-house and they had no clue what they were doing. It has ridiculous amounts of bugs and graphics glitches.

>>7934081
X/Y scrolling is cake IF you have no status bar (mid-frame X/Y changes)

https://www.youtube.com/watch?v=LF9HeIsELLs

that's why MMC3 makes everything better

>>7934069
>>7932297
Double Dragon manages V scroll in an MMC1 game (so there's no IRQ, only sprite 0 hit) and with a bottom status bar on top of it, along with active gameplay stuff happening (doesn't pause the action during V scroll). That must have taken some insane programming gymnastics and could explain why the game is so buggy.

https://www.youtube.com/watch?v=CTsyEnm3e6Q

>>7934108
It does. the scanline interrupt is much more predictable than Sprite 0 polling: the margin that your code will run is much smaller. It's not perfect though: the CPU does have to finish whatever instruction is was doing before the interrupt triggers, and this can cause some variance, but it is MUCH less variance than the time it takes to poll $2002 for a sprite 0 hit in a loop.
So what though you might think? How much variance could there be? Well, one CPU cycle is equal to Three pixels, and when you're trying to run code in a space of about 60 undrawn pixels (hBlank), you don't have time for many instructions and the variance can really fuck up your shit. This is why many games look flickery in spots that they change X/Y scrolling. Few games get it right: Even SMB3 has some flicker on top of its status bar. Kirby nails it though.

>>7934128
It was, what, one of the first games to use MMC3? I suppose it took a while to figure out how to avoid scanline flicker.

>>7934134
Pretty much, far as i can tell. There are some nasty bugs that SMB3 avoids too, such as palette / OAM drop the way that it does turns off the PPU late. They made it a bit flickery but it was probably the right choice at the time: If you turn off the PPU too early, very nasty things occur on hardware and they still aren't well understood to this day.

>>7934134
Kirby avoids the nasty hardware glitches by not turning off the PPU at all and just moving the "camera" to where the status bar is in a very tight amount of time.

see the fun thing about C64 is that you can make the VIC-II do cool stuff it's not supposed to like VSP and border sprites do by experimenting with timing and register writes. on NES doing this just results in graphics glitches.

>>7934120
There's not much actual gameplay stuff happening during the vscroll near the end of level 2, just some sprites moving around.

>>7934185
there are VIC revision issues there from what i understand when you start really mucking with it.

>>7934185
https://www.youtube.com/watch?v=TxrB0_6rSnc

Squish 'Em was a game we considered doing NES port of in /hbg/ but since it's vertical scrolling it might just be easier and make more sense to drop the status bars completely and use sprites for the score and lives counter.

>>7934120
someone ought to disassembly DD and find out exactly what the code is doing

>>7934228
interesting. the game is using horizontal mirroring, which isn't what you think it'd be using. it's loading all of the horizontal movement tile by tile into the 8x8 mask area on "the left side of the screen" as you scroll right. this allows it to use two stacked screens without penalty or moving the status bar or changing how the code works, which is how it's achieving limited vertical scrolling.
Many sidescrolling games like Super Mario Bros will use vertical mirroring and preload pieces of the screen into the unused nametable: this isn't the case here. the game does scroll slowly so it can easily get away with it.
i didn't delve into the code or anything but the PPU viewer here tells alot of the story.

LOZ used some kind of fuckery to scroll the screen up and it had to be completely rewritten to use sprite 0 hit when converted to cartridge because it would have originally used the IRQ on the FDS for the status bar.

>>7934269
>i didn't delve into the code or anything but
might provide some explanation for the millions of bugs in the game. two of my favorite ones:

>2:18 in the video I linked
that wall on the right side of the screen you can literally walk up
>Level 2 boss
you don't even have to actually fight that guy. When he comes out, walk back down the ladders until he's off-screen and the game will think you defeated him and advance to Level 3. I love doing that because I'm lazy and can't be bothered to fight him most of the time.

>SMB is probably the hardest game to emulate among the most popular NROM games, which are generally the first targets against which an emulator author tests his or her work. It relies on indirect JMP, correct palette mirroring (otherwise the sky will be black; see PPU palettes), sprite 0 detection (otherwise the game will freeze on the title screen), the 1-byte delay when reading from CHR ROM through PPUDATA (see The PPUDATA read buffer), and proper behavior of the nametable selection bits of PPUSTATUS and PPUADDR. In addition, there are several bad dumps floating around, some of which were ripped from pirate multicarts whose cheat menus leave several key parameters in RAM. If you're looking for a good first game for your new emulator, try anything made in 1984 or earlier, such as Donkey Kong.

>>7934269
I think the 1 in the 1P is Sprite 0.

>>7934678
Nope. It's this little guy right here. You would expect to find sprite 0 before the menu starts vertically.

>B-Wings, Fantasy Zone II, Demon Sword / Fudō Myōō Den, Fushigi no Umi no Nadia, Krusty's Fun House, Trolls in Crazyland, Over Horizon, Super Xevious: GAMP no Nazo, and Zippy Race. They write to CHR ROM and expect the writes to have no effect.
Copy protection check?

>>7910586
Awesome! 3do music please!

>>7934108
Crystalis does mid-line palette change (between the playfield and status bar I assume?) which is another tricky procedure, though maybe not as much here because MMC3 gives you an actual IRQ to play with. Some other games like Indy and the Last Crusade pull that off without MMC3 which requires some insane coding skills.

And TMNT not sure where sprite 0 is. The P in Pts?

>Teenage Mutant Ninja Turtles
>Uses Y scroll values greater than 239, causing the PPU to read the attribute table as nametable data before looping back to the same nametable instead of rolling to the next nametable down.

>>7934732
>Indy and the Last Crusade pull that off without MMC3
Right but it's also only the title screen where there is nothing else happening. It's not sooo bad to do it then.
There is another NES game that pulls off a mid-line palette change with no scanline IRQ. That game is Sea Chase =)

>>7934758
No. You won't find sprite 0 in the status bar, like i just said. >>7934692
It will be above it for a bottom status bar. You can look at the Sprite Viewer in Mesen to see what tile it is, or just open up the Memory viewer and look at locations $200-$203. Sprite memory goes: Y coordinate ($00), Tile ($01), Attributes ($02), than X coordinate ($03); and this repeats 64 times. A majority of games have the DMA sprite page at $200-$2FF; it's a fairly reasonable bet that it is there.

>>7934764
And Fantastic Adventures of Dizzy and Fire Hawk and Super Off Road. Some games also switch CHR tables in midline; eg. Pirates!.

These games also share something in common; they were all made by British developers. Presumably with C64 experience where trickery like this was commonplace.

>>7922967
There's the Jazzy Hip-Hop Earthbound one. I don't think they make too many hacks to the game itself, but it sounds awesome.

There's also Chrono Trigger Plus or whatever, which adds the video intro, and has a bunch of changes. I don't think CD audio is that good over the native SNES output though. The SNES music is absolutely amazing, and replacing that is blasphemy.

Whoa. This is a weird one. That right side of the screen right there? Masked with 15 8x16 black sprites LUL. Sprite 0 is one of those. I drew a yellow border on it.
No wonder this game is so damn flickery. I don't even know why you would bother masking this because most old CRTs would cut off these 8 rightmost pixels anyway, and it hogs up 1/4 of your sprite table.
Anyway, here's some fun with moving it about.

>>7933864
https://romhackdb.com/
This attempts to mostly do the translations, although its updates are slow & only considers the most recent patch.
This guy started a No-Intro renaming scheme for patches:
https://github.com/Earthsouls/RHTPP
https://discord.gg/MQqfErbDZZ

Hashing patches can be irritating, because multiple hacks are prepatched & each patching software makes a different version of the same format. So, each IPS software will make a different patch in which Floating IPS makes the smallest IPS & BPS patches to my knowledge. Some people, especially the Pokemon hackers, don't mention which version of the base ROM they used when making the patch. Some seem to use tools & decomps that only cover the v1.0 ROMs & then make patches with the v1.1/Rev 1 ROM. This increases the patch size by 1 to 6 MB depending on which format & software was used due to the official ROM changes.

In SNES cases, they'll either have a patch made where the base ROM was unheadered & they used a headered hack or vice versa which means the IPS file is around the same size as the base game. If you use the patch on an unheadered ROM & it adds a header, the hack was headered & the base ROM was unheadered. If you use it on an unheadered ROM & it doesn't add a header, but removes the header when the patch is applied to a headered ROM, then it was meant for headered, and not addressing this will not produce the proper ROM. If you use the BPS mode of Floating IPS with an unheadered SNES base ROM and a headered hack, it'll skip over the header, and the patch will produce an unheadered hack.

It's better to remake patches with the proper base ROM for accuracy & to save space. Using the proper base ROM will make a patch that's smaller than the incorrect one, and there's no use in maintaining multiple patches that produce the same ROM. A decent portion of RHDN contains incorrect patching info in the descriptions.

The Secret of Mana Turbo dev also uses the ZPS format that no one else uses.

>>7934861
Might that also explain using Y scroll values over 239? I'm sure it does explain why the status bar breaks up all the time. It might also depend on if the code loop runs off the NMI thread or the main CPU (LOZ for example is all NMI).

>>7934861
>I don't even know why you would bother masking this because most old CRTs would cut off these 8 rightmost pixels anyway, and it hogs up 1/4 of your sprite table.

Maybe they were testing it on a PVM-grade professional monitor or something with a square display and didn't bother accounting for normal consumer TVs because they were in a hurry to finish the game, which since it was a licensed title seems likely.

>>7906287
I want some good 2 players or co-op rom hacks for nes, snes, sega or whatever. besides super mario 2 player and tetris 2p , what else is there?

>>7934887
>Might that also explain using Y scroll values over 239?
No, that's something different and unrelated. The NES is 256x240, so, when you put 240-255 ($F1-$FF) into the scroll register ($2005) as a Y coordinate, the PPU becomes unhappy. It shows "pixels -15 to -1" at the top of the screen, which is erroneous junk from the previous Attribute table as Nametable data.
Here is an example of messing with the Y scroll value and demonstrating what happens when it is invalid: It just shows "garbage" at the top of the screen.

>>7934887
If i had to guess it's a "menu flicker reduction measure" so that the CPU has a little bit more time to process the frame. The menu still disappears when the game is busy, but, it would probably be a little worse if they didn't do that. You can see how the top few scanlines have some of that garbage data actually >>7934861

>>7934958
so is just sloppy coding that it uses Y values like that? i can't think of another reason for that.

Score bar breakup is not uncommon in a lot of games when too much stuff is happening; SMB for example has that issue and Double Dragon. I don't recall LOZ having that issue though, even in the dungeons with like 8 Darknuts on screen at once.

>>7934989
by moving the game down a few pixels, you have a tinyyy bit more time before the sprite 0 hit, so in theory the sprite 0 hit would miss less / menu would disappear less. that's my thought anyway. either way it's pretty sloppy, but, might actually be effective; you'd have to "fix" it and try running the game to see if there is a difference in menu disappearnece.
it's weird that they cared enough to cover up the right 8 pixels with 1/4 of the sprite table and didn't care about having a few junk pixels at the top. very bizarre.

Status bar breakup is not uncommon in a lot of games when too much stuff is happening; SMB for example does and Double Dragon. I don't recall LOZ having that issue though, even in the dungeons with like 8 Darknuts on screen at once. Tons of slowdown but the status bar doesn't break up (that I remember, been a while since I played it).

>>7935014
The status bar static is an MMC3 bug. Only games that used the MMC3 memory mapper chip have that problem. Mario 3 is the prime example.

Zelda used an MMC1 which didn't have that bug

>>7935014
> I don't recall LOZ having that issue though
It never scrolls when there is any action. All of the scrolling is done in the "transition periods". The "breakup" only happens when the game is too busy to process the Sprite 0 hit because of other action happening, LoZ never has to worry about that because the screen is always "squared up" whenever the game is being played.

also what the hell emulator did they use to make these? the colors are way off. it never looks like this on a real NES; it's an electric blue not this purple shit.

>>7935026
>The status bar static is an MMC3 bug
Not quite. It's the result of shutting off the PPU while the game is rendering. The "static" part is that it never quite happens at exactly the same time each frame.

>>7935030
Looks very blue on my screen. It's #4200ff. Probably looks a little lighter on real NES and a CRT.

This topic is always a bucket of fun =)
The NES does not generate colors according to RGB, YUV, or even the NTSC standard; it basically "zaps" the NTSC colorburst and "tricks" it into generating colors: and it doesn't even do this correctly. It depends on how the TV interprets the wonky ass voltages generated by the console: some TVs the blues are purplish, some TVs the purples are blueish. Neither is more "right" or "wrong" than the other. Age / heat / capacitor life can throw the colors off too in both the TV and the Console. Fun times!

>>7935065
And for real fun times in Your Romhack: Use "black" color $0D: It is "blacker than black" and is close to the vBlank refresh signal and will cause a real CRT to lose horizontal synchronization and glitch the fuck out =)

>>7935065
That's a popular misconception, the NES used a fairly correct hue range.
Granted the luma wasn't as correct, was square waves and only used 2/3 of the dot crawl rotation (caused jagged color collisions) plus was about 10% brighter than normal, but that mostly screws with digital decoders that expected the final strict NTSC standard.

The problem was most CRT televsions did not perfectly follow the NTSC color decoding standard.
NTSC used a skewed hue gamut, more range was devoted to orange and cyan.
But many televisions used a cheaper more linear color decoder, this is why fixing skin tones would mess up the sky color & vice versa.
So the sky in SMB1 was indeed blue (though a light pure blue is a shade of Blue-lavender ($FF8080) , which appears slightly violet, but is not purple)
Also, these "accurate" palettes don't take into account most people had their TVs adjusted to strengthen colors such as red, yellow & sky blue.
Later consoles shifted the colors more in-between the standard and non-standard hues to look more consistent, but those still had issues that modern digital decoders dont like.

So the proper NES hues are: azure, blue, violet, purple, cool red, orange-red, orange, golden yellow, lime, green, aqua, cyan.
The cyan can throw people off, it's Mega Man's lighter color that people assume is supposed to be purely light blue, nope, it's that mana/neon cyan.
Well, the "reds" too, games had to choose between the cool or warm red. The yellows only looked right if used next to darker colors.

So in other words, there is no "perfect" NES palette because each developer had their own tint-shift they preferred.

>>7935030
it could be NESticle which had a notoriously wrong color palette

>>7935031
C64 games also suffer from frequent raster split flicker, although for an entirely different reason.

>>7935075
in three different CRT TVs and one flat panel that I've tried my toaster NES on, the colors were consistent on all but one of the CRTs and that was an ancient set from the 70s. that set seemed to want to display yellow rather than green which made the NES palette look way off. for example this dungeon was more of a golden color on that TV. cyan (eg. in the SMB underworld levels) was mostly blue and had a much reduced green component in it.

>>7935087
should add this dungeon was definitely a bit greener on my TVs with not as much red component as these screenshots

>>7935087
Interesting. i've had issues with blues and purples on every different CRT i've tried on. Sylvania, RCA, Toshiba, a shitty Superscan, and finally a Trinitron recently. None of them can ever seem to agree. Hell, even composite and RF don't seem to agree either on the same damn TV!

The TVs I used were a Bravia and two 90s Thomson sets (I'd expect those to have the same color decoder) and a Panasonic color portable from 1978.

>>7935105
Never looked like that on any of these TVs. The sky was always powder blue not aqua (this looks more like the sky in SMB3) and the bricks were a dull rust color not this bright red-orange.

depends as well on what PPU revision you have since different ones can have slightly different colors

>>7934108
>>7934736
the dialog boxes also switch palettes. however the game pauses while displaying them so changing the palette in hblank is relatively easy.

>>7934736
>>7935167
> Crystalis does mid-line palette change
Crystalis does not change the palette mid-frame. It keeps the text box / status bar colors in the 4th slot.

>>7935167
>changing the palette in hblank is relatively easy.
it is not.

>>7935167
>changing the palette in hblank is relatively easy.
It is not. First, you must determine when hBlank is. This has it's own synchronization issues. Then you have to shut off PPU rendering and set the PPU address pointer to the color you want to change. This is all of the time you have in that hBlank, so, you have to wait for the next scanline. The background color will be the color you are pointing at, so, consider that. While this line is rendering, load the new color you want to change and nametable address you want to restore into the A, X, and Y registers. Wait an appopriate amount of time. Then, when the next hBlank starts, write the new color to palette RAM and restore the nametable address to the PPU address register. If you don't do this in a vertical multiple of 8 then your Y address won't line up properly.
There. You changed one color. If you want to change more, you'll have to sacrifice more scanlines or accept a rainbowy mess drawing on the screen.
now you can properly appreciate how fucking smooth my shit is =)

yone have a patched ROM of Contra Hard Corps with these 2 patches one on gop of the other :

https://www.romhacking.net/hacks/797/
https://www.romhacking.net/hacks/450/

Been trying to apply both patches to the same ROM and after applying the second patch the ROM becomes orrupted and dorsnt work anymore on an original Genesis with a flashcart.

>>7935239
it may just not work. sorry =(
we had a discussion about it >>7915230

Manhattan Project shows a major improvement over TMNT in the quality of the programming (so does TMNT II for that matter). They also manage flicker-free MMC3 screen split.

>>7935075
You copied that reply I made to a SMB1 colors thread a few weeks ago XD

>>7935239
No idea if that could help, but tried applying them in the opposite order?

>>7935014
Zelda was also originally a FDS game and the screen split would have used the FDS's IRQ generator. For cartridge conversion they had to switch it to use sprite 0 hit.

Earthbound has very clean 8 way scrolling on MMC3 but unlike SMB3 it also doesn't have a status bar.

>>7935246
that was my assumption but considering the author wrote that it was possible to combine both patches i thought it could be done.

>>7935741
yes i did, several times with different ROM dumps just in case my old early 2000s dumps were not good.

Anyways, whats the best way to play Contra Hard Corps for the first time? should i go vanilla Japan version or US version patched for multihit?

>>7935818
As was the case with Zelda II and that also has status bar breakup when too much stuff is happening.

yes, Commando on the NES is indeed an awful mess full of graphics glitches and even the screen momentarily blanking. Capcom really had no clue what they were doing at first.

What're some real good DS and 3DS romhacks? Barring QoL patches for the DS Castlevanias and MegaMan BN5 & SF1, and fantranslations for Chibi-Robo Clean Sweep and Tingle's Balloon Trip, I haven't explored romhacks basically at all. I only just found out that NewerSMB DS, CTGP Nitro, and CTGP 7 exist.
What else is there that's worth trying out? I'm loving those last three in particular so far.

>>7937993
> DS and 3DS romhacks
There ain't much... There are 85 DS hacks listed on romhacking.net. I don't know if there are any 3DS romhacks: the system is a bit more locked down.

>>7938262
3DS was blown wide open years ago. I never saw any ROM hacks that weren't translations though, except the Majora's Mask restoration hack.

>>7938778
In that case it still comes back to more complicated games are more complicated to hack. I seem to remember it being fairly difficult to jailbreak and run commercial games on? Also you're going to need emulators with dev tools, i'm not sure about the state of those.

>>7938813
>I seem to remember it being fairly difficult to jailbreak and run commercial games on?
Not any more, lol. Any 3DS can be hacked to pirate games now.

>>7938836

Nice. Hopefully the romhacking scene catches up then. too young for my blood.

What are good some good Homebrew or Hacks for the GBC?

I really want to get into nes dev. I learned a little bit of NES Assembly... but C looks way easier. If I just want to do something simple like a small DQ/FF style RPG will I take up too much space and/or have to figure out mappers?

Spent a few hours playing Beyond Gaylay online with rollback tonight. Its awesome! The balance changes are appropriate. The new characters like Wolf, Raichu, and especially Skull Kid are fun and fit right in.
The only real complaints i have are the new female announcer and voice acting are fucking terrible. Otherwise it is a very promising project.

>>7940108
C is not a viable idea on an 8-bit system. you're going to have to learn asm or gtfo. and yes you will have to figure out mappers unless you want to do Colecovision-level games.

C only became the norm in the 5th gen consoles.

Come back to me when they start properly backporting characters from the other Smash installments that AREN'T Wolf.
There are now two Wolves inside Melee.

oops it got all dried up
(you can now drag and drop images into the editor to replace textures)

>>7943027
Here's what it looks like on the editor side.
Excuse the botched 3D viewport. It's not quite ready to handle proper emulation of the color-combiner.
