I allready have one actually, got it a couple of months ago. I haven't actually used it very much yet. I've tried NES, GBA and CPS1/2 which all worked fine. Couldn't get Megadrive or NEO-GEO working, it wouldn't recognise the roms I had. Haven't looked into that further. SNES worked, but suffered from a little low framerate. That's all I've tested so far, I really need to study it some more.

The unit itself is pretty sweet. Has a fairly large and decent screen, and the button type and layout work fine and seem responsive enough. The menu system and method for installing and launching games wasn't the most user friendly, but you don't need to be very tech savvy to get your head around it either. The manual suffers a little from some awkward translation work, but is fairly easy to understand. All in all I like this unit, and it will definitely see some use from me every now and then.
