Texture Ripping Programs

[Garamonde]

That was quite informative jetters! Thank you for the help!


Also, what would be needed to get sounds right out of a game that uses dolphin?

For sounds, it kind of varies I think...
In the ISO files, there will be one (or even multiple) .BRSAR file(s) that contain all the sounds from Wii games that can be found in a folder labeled "sound" or somesuch (I'm not sure what format GameCube used... maybe .BRSTM?) and you will need a tool to extract the .BRSAR(s) to get the .WAVs or whatever format the sound is in (.WAV should be most common) out. I don't think there are many programs that can do this, so you would probably have to search for "how to extract brsar", "brsar file format" or something similar and see what you find.
I know that BrawlBox can extract .BRSARs from some games, but it doesn't work for everything.
Give those things a try and see what luck you have. Unfortunately I don't really know anything else about Wii/GC sound ripping.
