GameCube Sub-ROM Extraction

[Lazypsudeonym]

Hi there, all at EmuParadise.

Admins, if this is in the wrong place or has already been covered, I'm sorry.

I was wondering if anyone's ever extracted the sub-ROMS, if you will, from some of the GameCube platformers, like the actual games from the Legend of Zelda: Collector's Edition or the NES games from Animal Crossing. I tried, using some old tools that I'll link below, and I quickly found myself out of my depth.

Any ideas, EmuPeople?

The GameCube ISOs themselves were dumped using a modded Wii (because I'm lame like that).

Thanks, guys!

EDIT: I should probably point out that I'm using a Debian derivative and WINE to do this stuff.
