Fixed two bugs in the savestates. Older savestate versions will work now, as they should.

Added a queued frame counter to the MTGS to help keep keyboard input in sync with video output, which is needed now thanks to the INTC speedhack making the menus of some games run really really fast. ;)

Spiffed up the about box a wee bit.
