Hey, I'm trying to figure out how to rip the maps from the game Godzilla Destroy All Monsters Melee for Game Cube
I'm sort of new to the GameCube model and texture ripping and I'm having diffculty. Can anyone help me with this?
or point me in the right direction on what to do exactly for this game?  I'm suprised nobody ripped the models or textures yet.
