How to decompile / patch a gamecube game?

[laurelmcfang]

Hi,

Is there a way to decompile a game so I can say rewrite the calls to font_sjis.bin to change the Japanese text to English? I know that riivolutuon lets fan tranlators easily patch Japanese Wii games with English text, but is there a way to do that to a gamecube game? I'm assuming a patch replaces assembly calls to write the text and replaces the japanese text with english?

1. Extract all of the files from the iso/gcm by going to the game properties in the Dolphin game list and selecting Filesystem > Disc > "Extract All Files..." Save the files into a new folder on your hard disk.
2. Use the "Extract Apploader..." command and save the apploader.
3. Use the "Extract DOL..." command and save boot.dol somewhere
4. In the Dolphin configuration > Paths > DVD Root, browse to the folder created in Step 1.
5. In the Dolphin configuration > Paths > Apploader, browse to the apploader file extracted from Step 2.
6. Use the File > Open command and select the bool.dol from Step 3. The game should now start to play.
7. Exit Dolphin and start editing the files extracted from Step 1.

thanks will give that a try.

did that. thanks! now i just have to figure out how to edit the files! there are mostly in assembly correct?
just got an SSM ripper for the music tracks, but what I want to do is change the font from Japanese to English.
I am trying to get a translation of Giftpia into the game.

ok have to somehow decompress the .dat file i believe. sadly the resident evil decompressing is giving me an error.
Any idea on if .dat files are SZS files?

.dat for Giftpia is an SZS and was openable using these tools here: http://chadderz.is-a-geek.com/wiicoder/download.aspx

just to update this thread: giftpia.dat is a U8 compressed archive.
it can be opened using SZS modifier / Ctools in windows or with wszst in linux.
the hex codes are then put into an assembler for power pc 750 to see the assembly.
