Summary	08246: rescue, rescueb, aponow: Attract Mode is broken. Stuck in continuous game play demo.
Description	Attract mode is broken. Stuck in continous game play demo. After the initial showing of the title screen it is never seen again. Instead it runs forever in game play demo with the players helicopter never getting killed. Players helicopter will not hover over water and lower the ladder but instead will eventually go through the water and move through the bottom of the screen, reappearing at the top. Also games lockup after hitting reset "F3" at the title screen showing "RAM 1GHJK" Resetting during the game play demo fills the screen with zeroes and continues to play.
Steps To Reproduce	Load and run game.

No.19879 Haze Senior Tester Mar 9, 2022, 12:11	is it a regression?
No.19890 Tafoid Administrator Mar 12, 2022, 03:21 edited on: Mar 12, 2022, 03:40	I've looked at the first release (mame 0.25) through DOSBOX and it reacts the same way, the helicopter heads down to scrolls to the top of the screen at the beginning of the demonstration. I also viewed an actual cabinet where the demonstration is cycling at regular intervals which you'd expect. Leads me to think there may be a CPU core bug or decryption may not be 100% correct? I've only responded to the demonstration issue, not the soft reset issues as it doesn't crash MAME to prompt. Similar bugs had changed clear behavior which these games may also need: 08237 08068 Video of machine in play
