first things first. just because i'm mentioning rom doesn't mean i'm breaking the rules. just hear my question, and yes it's probably a dumb one. can somebody explain to me the differences between roms and isos? i've just downloaded the latest dolphin emu, and i'm crossed between the question on if it plays roms or isos. i know what they are, it's just the comparison of the two that's stressing me out. the only plausible conclusion i made up is that roms are from game catridges and that isos are from cd's. and also, do you play isos the same as roms, or do you need some kind of plugin to play isos on a gamecube emu? and if you need a plugin, does that count for all gc emus, or does it vary? mind you that these are questions. i'm not trying to go against the warez policy.
