Trenton, if I was to go down this route, I'd want an emulator that will run games like Zelda/Pokemon/Sonic. Any emulators you suggest?

Bod, there's one my friend uses called "My Gameboy" or something like that, will that run action/RPG's?

So the emulator allows you to play a game, and the ROM is the actual game file? You download these off the Internet?
