Random window mode switching fixed, Hyperspin favorites crashing fixed.
All that's left to do now is track down a few of my missing ROMs, mainly Neo Geo and Naomi stuff, and design some lighting configs for some of my non-mame emulators such as Visual Pinball, NES and SNES.
After much backwards and forwards with the bargain tablet I have decided to return it. Not because it isn't a great tablet, but because I cannot get all the custom ROMs and flashing tools for it that I would be able to get for more mainstream products. It's important to me to be able to install custom builds from the guys over at XDA and use a recovery tool like Clockwork Mod, so I'm going to go with something better supported in the hacking community.
