ld a, "A"

would this work? I realize I dont have to reset the outer loop of course

Something simple. Just a translation. The original yugioh game is so weird and nothing like the show or card game, so I figured I'd take a crack at it. It's very much a learning experience so no promises on anything too crazy.

I assume you mean a nested loop. Use the stack.
Start your outer loop, then push that junk on the stack, do the inner loop, then pop it off and continue the outer loop.

Might as well ask here, since I couldn't find any info anywhere else.

A couple days ago, I saw a video of an in-progress Fire Emblem GBA demake of Three Houses. The video got privated, and the link to their discord got taken down. Does anyone know if they got C&D'd by Nintendo, or if they're just laying low to prevent that from happening?

[Anonymous No.6204531]

Looking to get into translating PS1 games
Familiar with hex editing and learnt about all the relevant tools today (WindHex, xdelta UI, Monkey-Moor)
I've combed through the games bin with a hex editor and then extracted it all to see if I could finding anything inside, but just found hundreds of .PAC files with no common header.
I've tried using tables like Shift-JIS on both and still nothing.
Any willing to help or provide some resources online I can follow? Seems like it's just a matter of getting the right tbl file, pairing it with the correct file, then slowly editing each letter.

[Anonymous No.6204535]

This method is intermediate level, since you’ll need some debugging experience, but you may want to consider it once you get familiar with a debugger and can read a bit of ASM:
1. RAM dump when a text string is on display
2. RAM dump when the next text character or string appears. As closely as the previous one, the better. Next frame, ideally.
3. Compare RAM data

Besides timers (which are easily to spot), changes will be relatively few, and most of them related to reading text data, displaying font sprites, next character spacing, VRAM coordinates of font and palettes... All useful things you need to know if you’re translating from japanese, as you will not only be modifying text but also adjustment character spacing, the font, etc. You can spend an hour or two identifying these values (simplest way is to selectively modify data and see what changes in-game), and once you find addresses related to text display (graphics), or text data reading (the actual text), you can breakpoint on those addesses to find and document the subroutines and code that use and modify them.

You’ll very soon run into the actual text data. If it's S-JIS, you can start modifying character in RAM directly as a test. Once you've verified it's text, you can copy a chunk of that RAM data and search for it in the disc files. Some games have these files concatenated with several files (PS1 hacking of this level usually involved figuring out custom file packing and repacking), but also there’s games that have a "TEXT" directory in the disc, with plain text files. It varies wildy from game to game.

As I said, you will probably need to get familiar with ASM, tracing RAM addresses, etc... I recommend picking up these skills before attempting a full blown translation project.

I recommend this quick follow-along excercise using no$psx about locating some useful RAM addresses and doing basic modifications on Mega Man Legends.

https://youtu.be/aZxtts7HBNY

It's not perfect, but it's a serviceable hand-holding through the process of locating stuff on RAM and modifying it. There are three parts. Watch it all, but it's the no$psx debugging what you should focus on.

Don’t get too involved with the first part about using CheatEngine and ePSXe, it's informative. It's informative to learn basic concepts, but the method itself is tedious and unnecessary (there's literally nothing in that step you can't do directly on no$psx). You can more easily start finding useful RAM address using my method described above: comparing RAM dumps before and after a relevant change occurs. You won't need to dump the whole thing each time, as you'll be narrowing down the relevant address ranges as you go. You can also use known GameShark codes for the game to locate general RAM ranges where a certain type of data is stored (GameSharks format is simply [RAM Address][Value to write]). For example, basic playthrough information (think stuff you'd store in the savefie) is usually one big table of values. You can use those as start point to tracing your way into various aspects of the game you need to change.

Check the video, learn to find basic useful RAM addresses (remember to check known GameSharks), learn to read the subroutines that write and read those values, and learn to modify a few instructions on those subroutines. For example, you can try removing the instruction that reduces your HP values when you get hit. That's a basic invincibility hack. Congratulatios, you're a romhacker. After that, you'll have the basic foundation to start working on what you're aiming to accomplish. (We can talk about disc file handling after you're actually able to change something)

A few more resources to keep on your bookmarks. You won't need them today, but you'll definitely want them handy when you start modifying subroutines:

An explanation on the basic few CPU operations you'll find in assembly languages.

https://ipfs.io/ipfs/QmXoypizjW3WknFiJnKLwHCnL72vedxjQkDDP1mXWo6uco/wiki/MIPS_instruction_set.html
MIPS instruction set. These are the actual instructiouns you'll be reading while debugging assembly code, based on the basic operations explained on the previous article.

http://problemkaputt.de/psx-spx.htm#cpuspecifications
Nocash's PS1 documentation. The CPU Specifications section is a PS1 debugging bible. Here the instruction set is explained further in the context of the no$psx debugger.

Holy shit thank you so much. You really want above and beyond here giving me all of this.

I've tried getting my game to work with no$psx earlier but it would just throw a fatal error.
Tested with MML and that's working though. I'll see if there's any workarounds or if an earlier version works.

I'd love to stay in contact if you don't mind. Do you have Discord or anything similar?

I know exactly what you mean, but I wonder if it's because the original game with its maps and secrets made such a huge impression on the doughy brains of children, that it still carries over to mods.
Trying to capture that feeling is pretty much the goal of my own hack.

I'm working on some hacks to make games zoomer friendly. Unlimited lives or unlimited continues. I want them to work on original hardware and some flash carts don't support cheats so I have to patch the ROM. With a good emulator that has a good debugger this is a piece of piss.

Turns out the debugger in mednafen works well enough. Maybe not as cheat friendly as FCEUX but easy enough if you know what you're doing. And have a magnifying glass or a 640x480 screen. As for good emulators that's a big lol from me as well. They're great toolf for debugging but even my zoomers don't want to use them.

To follow up on this I found a site that has a bunch of PCE/TG cheat codes for emulators. Now all I have to do is search the ROM for a write to the "unlimited lives" address and change the code. Since I know the opcodes I can just do the disassembly, changes and assembly in my head so it only take a few seconds to patch a ROM. I decided to go with unlimited/255/99/whatever lives and not other with continues. This way my zoomers can 1CC games on original hardware as the developers originally intended. It counts because flash carts aren't emulation.

So what are your top five favorite romhacks? Could be minor improvements or massive changes.

My personal picks:
* Sonic 2 Retro Remix (just for how it changes the gameplay of Sonic to make it more 3D Mario-like
* Super Metroid Arcade (similar concept, turning Metroid into a semi-rougelike)
* Pokemon Fire Red Omega (really, any of Drayano’s Pokemon mods fit for including all the Pokémon and adding modern changes)
* Super Mario 64 Land (again, I like how they took the 64 engine and modified it to make a completely different game)
* Link to the Past Randomizer (just for starting the randomizer trend)
