Homebrew what does shrinking gamecube iso's do?

[Dr.Killa]

what part of the iso does it remove to make it smaller in size?

is the part that it removes important, like music or multiplayer or something?

just removes trash/filler files. As far as i know it gets rid of no vital files. I'm not an expert but that's what i've read.

to my knowledge, in order to preserve the life of the gamecube the total disc size was 1.37 gig. meaning even if a game is considerably smaller then that, they fill up the rest of the space with dummy data so that way the gamecube reads as normal.

Shrinking the data dumps the dummy data leaving just the game alone, which is perfect for multi-isos (multiple gamecube games on one dvd).
