I don't understand all this lingo, and I need help

[Cubman14]

I just downloaded a Nintendo GameCube emulator. All of the emulators I've downloaded before work with roms, but I don't think this one does. Can you tell me exactly how to get the games that I own playable on my PC? Just give me a step-by-step direction. Thanks!

You should transfer the games in your PC by using LAN conection.
You shouldn't bother doing this because GC emulators don't play games yet.

Unless you're a hardcore emulation person interested in seeing a lot of glitches and having no luck with games then what belmont said is right.

And in terms of the lingo part of it all - You need what is called an ISO or a "disc image" - basically all the contents of a disc dumped into 1 large file.
