It's an open source ROM dumper. The unit shown has multiple cartridge ports including one for GBA games and a controller plug for the N64 so you can dump the Controller Packs. Even though there are adapters you can attach to it for Atari carts I would like to see a deluxe version that includes pretty much all systems plus a DreamCast controller plug for dumping the VMUs, a card port for GameCube save cartridges, one for OG Xbox, and one for PS1/2.
