The best emulator is still in development, it's called GPMicrowave, and it will allow my Gamepark to make popcorn while I'm on the road.
Ports aside, the must-play game of the year is Tobi Drummer. Simple though it may be, it's creative, original, and one of those rare games that fully realizes its own concept.
But I still need to play Gloop and Pinball Dreams! (Yeah, where have I been?!)
