A legal piece of advice: using emulators is permitted in all parts of the world. As long as you are using a game that you own the rights to, that can be a game you developed or bought a copy of. Having a pirated copy of a game or copying files from someone on the internet is labeled as piracy and is illegal. And will get you into trouble.

If your emulator requires a BIOS file, you must also own the rights to a BIOS. You can get a hold of a BIOS file by ripping one from a console that you actually owned.
