Summary 07186: area51mx, maxforce (and its clones): Maximum Force: Garbage graphics and attract mode freeze after a standard Game Over screen.
Description After I got a Game Over Screen without getting a high score in the game, the game didn't show the credits and instead displays garbage graphics (also, the sounds didn't play after that screen). After a period of time, the attract mode freezes during transition screen, and starting the game will go back to normal. This happens also on Area 51/Maximum Force Duo set except with an out of range message.

Here is the credits screen for Maximum Force if you didn't see it:
Steps To Reproduce Don't get a high score by doing nothing or keep shooting civilians.
Additional Information You can skip the game over sequence by pressing start and now the credits play normally without freezing the game during attract mode.

I've done some testing with this game. I've found out there's a regression version. It must be between 0.150 and 0.153:
There's no issue in mame 0.149.
In mame 0.150 and 0.151 the game doesn't load for me. It seems the chd file was changed and I don't have the proper version.
In mame 0.152 the game runs but crashes when starting a level.
In mame 0.153 the game runs correctly and the issue ocurrs exactly as in mame 0.205.

Do credits work after you get a game over screen on earlier versions of MAME?

Yes, credits work.
