In order to play an console game on your carputer, you will need to have an emulator (the program that runs copies the console's programming) and a copy of the game, commonly called a rom.
There are many emulators available for most consoles, except for the newest generations at this time. Emulators are also made for all operating systems.
There are special laws that apply to the usage of emulators, that you should be aware of. For more information, look at wikipedia.org
