Hey all, guy from the last thread here, I'm about halfway done with what I'm doing in regards to the pdretrogames private group, There has been a hell of a lot more than I expected and as such it's taking me longer than anticipated, hopefully I'll be done before this thread ends as well

gotta get in that step thru debugger dude and watch it when the text is loading and displaying. what system?

[Anonymous No.8807475]

>>8806406
psx, i found the buffer where the save file gets copied to, so i figured I'd find the player name in there and then find functions that reference that to then find a function that does dialogue to then find the dialogue, but doing a relational search in that chunk of memory doesn't find my name and it's definitely not in ascii or shift jis so it's probably compressed or something
i also found where party stats are in memory, and functions to get and set them, but i couldn't seem to find the name nearby, and the hud text is an entirely separate system from the dialogue
I've put it aside for a while but i have a 3 day weekend so I'll probably get back to it

[Anonymous No.8807774]

>>8807475
It's possible the whole save is compressed, but unlikely the character name is. What I'd do if I were you is savestate, name the player "AAAA*", save, reload state and name the player "BBBB*", save and diff the two. Might be enough to get you started.

what the frack

[Anonymous No.8808906]

>>8807774
hey that did it, thanks for the idea
it wasn't compressed and is a pretty normal looking 2 byte character encoding, with 01 00 being あ, 02 00 is い and so forth, so idk why my search tool couldn't find it
i guess next I'll just trace reads to that address and see if i can find a dialogue printing function
hopefully i luck out and all the dialogue is uncompressed and in that same encoding

[Anonymous No.8808993]

>>8808906
found the dialogue by manually figuring out the numbers from a string of kana, i suppose next up is trying to figure out where the pointer table is/ how the game is addressing the strings and try to get everything set up in Atlas
didn't really think I'd get this far, i imagine it'll get harder from here though

They are final.
In fact they require extra work because they usually use ~30 colors, so I have to use 8BPP sprites with a shared color palette for all sprites in the same map.
It's one of the things that the GBA does better than the SNES (it doesn't have 8BPP sprites).
>>8814529
With the git log and the pics and vids I'm showing I hope to do that some day.

You would have to rewrite the entire game in a different language. You might be able to automate it but you will also have to rewrite all code that interfaces with the gbc hardware to work with the gba.

It's not that surprising. It takes a lot of work to make a complete game and gbc pokemon hacking has never been as popular as gba hacking.

First time I've ever seen a translation cause such a slowdown. What's the deal? Is it made to work for just older emulators?

[Anonymous No.8821175]

>>8820537
Probably. The GBA has a very screwy memory achitechure. Executing from ROM is insanely slow, so most games copy the game code to RAM. If this patch wasn't aware of that shit, then it'd jump to somewhere in ROM and execute just fine in emulators that don't emulate different memory timings.

Fuck I completely blanked on that. Since the GBA is backwards compatible I thought it was built off of the GBC like how the DS more or less expanded on the GBA.

[Anonymous No.8822962]

>>8822879
Sorry, but when you read so so wrong things expressed as facts (without any hint of doubt) and nobody disagrees, we end spreading lies like the GBA is a portable SNES or worse.

With a GBA, executing code from ROM is very fast. In fact, ROM is usually faster than external RAM for sequential accesses, and it also provides ROM prefetch (but not RAM prefetch).
Using LUTs to speed up code is a very good idea, since GBA ROMs provide lots of space for them and reading them is very fast.

The only case in which executing code from RAM is faster is with ARM instructions (not Thumb) placed in internal RAM, not external.
But you only have 32KB that must be shared with the stack and with data that you want to be read fast too, so there's not much space left for code.

What most GBA games usually do is to place time critical routines in internal RAM as ARM intructions and executing the 99.9% of rest of the code from ROM as Thumb instructions, since they are slower but take less space.

Hell it's the case of modern games in active development. The people making games aren't likely to be the best. Sometimes someone else will look at it and say "why didn't you use a btree?" to which the guy who just made the entire streaming asset system will ask "what's a btree?".
This is why open source gaming should have been a great thing. Games refined forever by precisely the right autist who knows exactly what design pattern suits this particular game and is willing to retool the system to implement it.

On a scale of 1 to extremely, just how technologically inept are you?, You do realize that there's a lot more to be done with translating a game, right?, not just the translation itself but also modifying the game to actually support the new half-width characters, making a whole to graphics set just for those characters, and a whole lot more, don't speak on things you clearly have no actual clue about
