Summary	07960: timelimt: Sound broken after game over
Description	Time Limit has working sound for the first game credit. After the game over screen the sound is missing for subsequent credits.
Steps To Reproduce	Coin up a game Lose 3 lives Watch game over screen Coin up second play Sound should be gone for second game.
Additional Information	Last working release was 0.188. There were some updates to the driver for 0.189, one of which might have stopped the sound from resetting after game over. Also, there are notes in the driver about bad colors. The color PROMs were redumped for 0.189. I was under the impression that the colors were now correct in this game. I don't know if those notes were supposed to be removed, or if there are still known color issues.

No.18778 AJR Developer Apr 30, 2021, 03:53	I took out the reset line manipulation of the sound CPU through the addressable latch. The Z80 program's writes to B003 probably should have no effect on this machine, as it is set only once at startup but cleared on every game over.
