Unlike Datel's Action Replay Max Duo, this game-save manager from Gametech doesn't require any GBA-slot jury-rigging or an unsightly device that sticks out of your handheld like an air conditioner. All you have to do is pop your DS cart into Gametech's discreet USB dongle, hook it onto a PC with the installed software, and you're good to go.
This $30 device can be really useful for titles like Izuna: Legend of the Unemployed Ninja or SimCity DS, both of which having only one save slot. You can also keep a back-up of your progress in case you accidentally lose the game or decide to trade it in later.
