uncompress it to burn a disc then leave it as a single 200mb file on my computer because i have over 80gb worth of gamecube iso's and i might only have 56gb left 440gb just dont get you yhat far these days i ask around other places nobody could take 2mins out of there life to help me so i came here thank you
using either Phoenix or Gamecube ISO server you can have them remove all the junk data on an ISO or GCM file, it should make it a bit smaller
Use GCM utility, find with Google. That's best i have used to shrink those. I dont mean that multi-game-disc maker(same name), that other.
You cant compress images to size what u want, it compresses only to that size how much there is actual game data.
