Does anybody know the reason why BIOS_START_FLAG doesn't clear after game start, and REG_STATUS_A second bit is active from the very launch, althought I never inserted a virtual coin into chute №2 (this bug was found when I tested the game with US MVS U4 bios)? Because of these bugs continue function immediately return the player to the normal game, without any coin insertions and start pressing.
