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.

That's really the basic idea.

ROM from cartridges, which use memory chips.

ISOs are images from any type of data disc.

They're labeled like that to distinguish the original source of the data. Well, that's what I learned anyways :p
Correct. Although whilst ROM is a term ISO is merely the most popular CD/DVD backup image filetype which therefore has become a term eventhough Nero for instance use .nrg instead of .iso for it's CD/DVD backup images. Also Nero is just one example, there are still a bunch of other CD/DVD backup image filetypes besides .nrg for Nero and .iso as well.

they can be considered to be both the same thing

Both are an image of a storage medium made as a backup.
