Ok, I went digging through the options on Ms. PacMan the other night, I couldn't leave well enough alone. I turned on the "service mode" in options page, the screen flashed, sort of locked up. I had to exit and restart. Now, all my pacman games are unstable. They start out slow, sound is skipping, then the entire game speeds up to turbo speed. then it slows down and glitches, then speeds up. I've tried deleting all the pac game roms, reinstalling them, no help. I've gone back to the options menu and turned service mode off, then on and off again about 30 times, same thing. I've tried resetting the game, I've reset all the options in the mame properties window from the GUI to default, it still is acting the same. I tried using an earlier version of mame, 37b5, it still acts up. I am currently using version 61, using mame32 for windows. My other games are working fine, it's only the pac games. I've read the other topic about game cheats and speeding up the pacman, that's not my problem. Any ideas or help would be greatly appreciated.
