First off, I'll have to give you a watered down explanation on the difference between an Emulator and a ROM. An emulator can be thought of as "the console" and each ROM file could be thought of as "a game." You need to open the ROM file with the emulator, just as you would need to play a game cartridge on its own console.New Super Mario said:So can you explain this more? What's the difference between the two ROMs?
