Apple Mac computers are thousands of times more powerful than the classic consoles and computers of the past. With emulation software, OS X can emulate classic games consoles like the Atari 2600, NES, Sega MegaDrive and Super Nintendo (SNES).

All you need is the right emulator software, and compatible ROMs (these are small digital copies of the original game cartridge). Get a working emulator and a working ROM and you are good to go.

Video game emulation software tends to be developed by enthusiasts, and has--in the past--been somewhat scattergun in its compatibility. Multiple emulators were available for the same consoles, and they would run a different selection of ROMs. The great news is that a new OS X app called OpenEmu has taken over and made the whole process much easier. OpenEmu isn't an emulator itself, but an interface for all the different emulators. It handles installation of emulation devices letting you get on with finding ROMs for your favourite games.

Where can I get arcade ROMs from: and are they legal?

A classic console game running inside Mac OS X

We should talk about ROMs and issue a disclaimer. It is generally illegal to download a ROM of a given arcade machine (although the minutiae of copyright law could be discussed for years.) In reality, it's a grey area and you are unlikely to get into any trouble with the law for possessing a ROM of your favourite console. It won't take long for you to find the ROM you are looking for, just type "rom" into Google. You download ROMs as zip files from the site.
