I don't think Game B scores correctly in Diamond Hunt. The manual says that successfully crossing Game B should award 50 points, but every time I've done it, I haven't received any.
In addition, Donkey Kong Jr. (Tabletop/Panorama) has a really weird bug where nothing in the game moves after I unlock DK's final chain except for DK Jr. himself until I hit a bird with fruit, die, or unlock DK's next chain. I know you're busy with the next version of RetroFab right now, but I hope that these issues can be addressed quickly. Keep up the good work!
