ROM Hack [POC] Rhythm Tengoku The Best Plus Hacking

[ElyosOfTheAbyss]

I did a test and you use a recompiled text zlib because it crashes the game

I know how to open .sar files. If you want to know I can tell you if you want.

Please do. Any help given is appreciated.

 

[ElyosOfTheAbyss]

.sar files are actually .sarc files. All that nintendo did was remove the c

You can open the files in every file explorer and dump files from there. The only thing is that you can only dump them as .bin files and you need to use a hex editor to see what type of file they are.

oh man I love this game I do hope this works for a fan translation

Well, at the moment it isn't possible without a different tool to compile it.

 

[foreveryang]

aww well that's fine, maybe someday :V

 

[ElyosOfTheAbyss]

THe game doesn't like it when you edit text :|

 

[foreveryang]

i wonder why

 

[ElyosOfTheAbyss]

It's probbaly the tool to compile it back into .zlib because the file size is like 100mb smaller if you decompile the then compile pajama.zlib

yeah, we'll probably need a different tool for injecting stuff back in, and I don't know enough about coding to do it

 

[ultramario1998]

right, messing around with the .sarc files. lots of unintelligible hex, but we're getting closer

I've been trying to follow this, but every time I try to extract the file, it just extracts the same file (00000004.sar) no matter what file I try. Am I doeing something wrong?

The program names files according to where they're found in the zlib. All files are named 00000004.whatever because they're all found 4 bytes in.

All right, I read through some more of this thread and I'm starting to understand it a little better, but what am I supposed to do with the file?

I used EFE to dump the files, but I'm not sure what to do with the resulting .bin files...

I was only ever to edit graphics (cgf) files, using Ohana. If you're interested in the other files, you're better off asking @ObsidianB who figured out the text and started a fan translation (before last Direct, of course)

Open them in a hex editor. Look at the header and it should lead you to the file extension.

Noice

Okay, getting closer. I found and dumped the textures for the 3D games (Airboarder and Rhythm Rally), but I can't find where the 2D textures are kept. I tried cellanim, but it dumps them as .sar files and not .cgf files, like the 3D games.

Once you've got ROMFS extracted you can use my tool set here: https://github.com/ObsidianX/3dstools

Most *.zlib files are zlib-compressed SARC files (use sarc.py). Make sure you use the zlib flag (-z) when you're extracting/creating the SARC files. If it isn't a SARC file then you can decompress it by trimming the first 4 bytes (the size)

romfs:/messages/pajama.zlib has all of the text, use msbt.py to convert to JSON and back to msbt. I have some pretty obtuse support for MSBT's colored text support which you need the (-c) flag to enable. Apologies in advance for the JSON format.

romfs:/layout/ has a ton of 2D textures in BFLIM format (use bflim.py). bflim.py currently doesn't support creating ETC1 compressed images but I found the game did just fine with the larger RGB/RGBA formats.

Ok, total Python noob here, but I'm inputting the "extract" command, and nothing seems to be happening. I've CD'd to the correct location, and I can even see what's inside the file, but extracting does nothing.

Can you post the exact command you're running?
