Hacking Wii game graphic assets

[brookswashere]

I am trying to view the original art assets from some of the Wii games I own, games that I already have a viewable iso of. Specifically No More Heroes 1 and 2. Is there a standard graphic format for textures across all Wii games, or does each company kind of do their own thing? Not trying to manipulate to put back into a playable game, just wanting to view and export into a workable file format. Can anyone tell me IF this is possible, and if so point me in the right direction? You have a great site, and I hate to be a first post request, but this has really been bugging me.


Thank you,

The company uses whatever format they want to, there isn't a standard. If you just want textures, you can use the emulator Dolphin to dump textures.

Grasshopper Manufacture uses in-house rsl archives files. Inside those files are gamecube texture files - which have a large overlap with TPL files. The magic is GCT0. You can perhaps use my Fatal Frame tools on here . They should take care of the different formats. For formats we didn’t bother to implement, use the exploder to separate the GCT0 files, and make a TPL of the same dimensions using gxTexConv. Then swap the headers, and extract using Zetsubou.


Also, matlab script for S3TC and I4 stuff is available at:

Just run it from MATLAB on any folder full of RSLs and it will extract all CMPR/S3TC and I4 formats easily. Grasshopper uses S3TC/CMPR for textures, and I4 for fonts. Both formats are indentical to TPLs (with header changes).


I can not guarantee these will work with No More Heroes 2. (or even No More Heroes). They should work okay-ish. I am not supporting these tools, and have no intention to adapt them to fix bugs.
