|Summary||00363: balonfgt: When you try to play balonfgt using both screens, the 2 screens get out of sync almost immediately.|
|Description||When you try to play balonfgt using both screens, the 2 screens get out of sync almost immediately. Maybe they didn't care about sync because the screens aren't synced anymore after a game with only 1 screen.|

|Any chance of getting this fixed? This is a fun game, and it would be nice to be able to do a 2 player game. I tried starting a 2 player game and I didn't notice a sync problem with the video particularly (it was only a test, not a full game), but the audio didn't seem perfectly sync'ed, which made the audio sound irritating. I wonder if the problem is not as bad as this report makes it sound, or if the problem has gotten better due to changes between v70u5 and now.|

You start a 2-player game using both screen, you'll notice the game gets out of sync before playing for a minute.
This is old information more than four years ago I received.
According to the information provider, this is caused by wrong CPU emulation time slice. It has to switch CPU every half scan line clock (approx 113.6 / 2) to synchronize properly. But in MAME switches it every 112 clocks or 113 clocks.
I have a sample program to prove that the theory works correctly, but I can't make it public for some reason.
