The Atari 5200 Ultimate SD Multicart is super easy to use. The cartridge is well constructed, looks amazing and even includes a reset switch I normally prefer owning physical cartridges for my favorites games, but some great Atari computer ports for the 5200 were never sold in a cartridge… M.U.L.E. was one that I REALLY wanted to try out on my 5200. This device allows me to play those games along with home brews and demos. Of course it can also play all the commercially released 5200 games. I would highly recommend this cartridge to any serious Atari 5200 fan.
Thanks to Steven for making the Multicart SD and 8-Bit Classics for including it on their website.
