Hacking Utility to read region/game id from GameCube ISO?

[kiwisoup]

I have many GameCube ISOs and am wanting to verify that they are NTSC-U region, because they were not labeled by their region or game id which would also give away the region.

Is the game id or the region embedded into the iso where a utility could read it from the iso? I'm having trouble finding one, and I know there are ones for wii games.

Try the dolphin emulator, that can tell you the region of the games
