Title: Sound problems (music stuttering on early 80s games) on .152 but not on .146.
Post by: msingleton1977 on June 20, 2014, 02:47:13 pm

Having a problem on 80s games (like PAC MAN) under .152 where the music will stutter frequently. It only happens on the early 80s games. The late 80s and 90s games are fine. The problem doesn't occur when I launch .146. Any ideas?

Thanks guys!

Monty

Hi msingleton1977,

You just need to enable -multithreading in mame.ini. This option was enabled by default in previous versions but was disabled recently for stability reasons under certain circumstances. This option makes it possible to detach the emulation speed from the video card's refresh and still remove tearing (i.e. it allows -triplebuffer to work). The typical case of this is Pacman, where the game natively runs at 60.60 Hz but in order to emulate it on a horizontally oriented standard arcade monitor you need to use a 288p@52Hz mode.

Calamity,

Your genius never fails! Nailed it! That fixed the issue.

Thanks again. My cabinet is finally complete...again. Couldn't stand it that such a great upgrade that was .152 broke PAC MAN.

Now I'm going to image my cabinet and never upgrade again. :)
