Hey guys, I'm selling this QJ Game Action Replay for Nintendo, I've read lots of cool things about this device. Not to be confused with Datel's Action replay, this one lets you save your game ANYWHERE and continue easily from that point. As well as other features like slo-mo. I haven't tried using it, just thought I'd take offers.
EDIT: I have verified that it still works! I was just saving and resuming games of Mario Bros! Very cool!
