Most of the other games I tried worked and played well. It should be noted that not all games are supported, for example the 1 meg Pokemon rom turned into 2 megs when converted into .pdb format, and I was warned that it might not be supported. The demo version only supports roms under 32k in size, which severely limits the number of games you will be able to test out. A great feature of Liberty is that on the IIIc you can colorize the display by customizing the grayscale palette. This greatly improved the visibility of the games, and went a long way towards enhancing gameplay.
Most games work great on the emulator, although speed is still an issue.
Action games run slowly, and when you play the game on a real GameBoy you realize just how much slower the emulation is. The value of being able to play thousands of games on your Palm is quite an attractive offer though. Playing my Favorite GB game ran great. The only thing that isn't perfect about it, is the sound. Due to a real speaker on a GB and a bleep speaker on Palm machines, the sound is less than acceptable.
