This had been bugging me for a long time, and it's entirely possible you've seen it before. But on the Genesis game, at least on my emulator, when I press Up, A and Start all at once, it instantly ends the level by putting the time to 00:00. It had only been a minor annoyance until it cost me the solution of Watch Left or Right (Part Two) which is Sunsoft level 22. >_<
It's quicker than using the nuke function, but far less fun. =(
