GCN Customizing Gamecube Iso (Editing Textures and/or Text)

[MaxBlueyes]

Alright so,

I live together with some friends, and we play Mario Party 5 & 6 a lot (the best of the bunch imo) and I was wondering: Can I replace the textures/texts in the game? I know it would be a lot easier to edit textures in Dolphin but I would rather want the changes made on the ISO itself. I backupped my games on an external drive so I play all my GC & Wii games from there.

If anyone has some experience with this and would like to give a tip I'm all ears! I know people were doing it with Animal Crossing already, so it should be possible.


Sincerely,

Max

I doubt there is a formal tool for this game (very little that was not mario kart or smash brothers saw attention on the GC)

To pull apart the isos

There might be better choices out there, certainly is for the Wii and most other systems with file systems, but if doing single games that is not so bad.

For a hardware document then you will probably be pointed at
http://hitmen.c02.at/files/yagcd/yagcd/frames.html
Chapters 14 through 17 cover a few formats, though you will also want something to cover "yaz0" compression.
That said the source code to dolphin probably has more info in terms of pure hardware
https://github.com/dolphin-emu/dolphin
https://dolphin-emu.org/ and the wiki there, should also have some half reasonable debugger options if you want to go that way but I have not tangled with them in a long long time so no idea what goes there now.

Whether it uses the basic formats or something more custom (while they are the formats Nintendo provided)

Being a 3d console then most times the basic 2d tile editors will not be up to much, though grab at least something like
https://github.com/barubary/tiledggd
https://wiki.vg-resource.com/TiledGGD (said site also has a few more formats you might encounter)

Text, assuming it is not graphical (low text puzzle games often have quite a bit compared to say a RPG with a script the length of a short story), should fall under the usual policy for editing text -- you can try finding it with a relative search and then making a table, doing pointers and figuring out any formatting issues.
