Interaction between BIOS and 68k side is not fully understood. The BIOS often doesn't register that a game has been started and leaves the 'PRESS P1 OR P2 START' message onscreen during gameplay as a result. If this happens, the games usually then crash when you run out of lives as they end up in an unknown state.

Incorrect behavior at time out and there are some sms based games which aren't yet fully supported.
