I really wish that Genesis handheld they do with Super SF2 and Mega Man on it actually worked right. I don't mind it being a little off on the audio and video, it's a convenient little emulator box with a solid screen, control setup and speaker plus with the SD card you can load whatever to it, but the saving is a deal breaker.
It makes me wonder with this better step in quality they seem to be taking with other systems why they don't revisit that and make good on it.
