We will examine and use the Ultimate Cartridge designed for the Atari 8bit line of computers. This cartridge allows you to emulate any 8k, 16k or any other type of cartridge ever created for the Atari computers. It accepts an SD card for placing ROM or CAR files that can be executed at startup thus emulating the original cartridge.
