Yeah, the game has issues. I figured out how to play Adventure at least. Go to the folder where the game is installed, then create a batch file. In that, I wrote:
2600 "Resources\Atari 2600\ROMs\ADVNTURE.BIN"
Then run the batch file, and you can play Adventure. Just change the ROM name to whatever game you want to play. I'm sure one can make an automated batch file that lets you choose a game by name, it'll just take some work.
