MAME, or Multiple Arcade Machine Emulator, is a software that allows you to play several games on your computer and, therefore, without needing a console. It emulates a thousand different arcade system boards and is capable of reading roughly 5,000 original and clone games.
Available games include Pacman, Donkey Kong, Tetris, SEGA, and much more. To access these games, you simply need to have the original program code and graphics stored on a read-only memory chip or ROM. (This can be easily downloaded off of the Internet.)
This program is ideal for both beginner and expert gamers, and its interface is fairly easy to use.
