I set up save state = "U" and load state ="L shift U". It works "sort of". I tested it with 3 games. Ladybug, Congo Bongo, and Popeye. It saved a game and reloaded the saved game. When i tried to reload a saved game from Popeye, it loaded but most of the graphics were gone. I could continue to play but all the steps were gone. The Ladybug and Congo Bongo loaded just fine.
