Also, in Donkey Kong II when the key is in the upper screen and you lose a life, the key doesn't reset back to the starting position. iirc it does on the actual device, both in game A and B.
You're right! Well spotted. The key should reset back to the start on a miss. Thanks for letting me know :) I've uploaded a patch with the fix. Thank you for helping to improve the accuracy of this simulation :)
