Got it working, but when I fire up a game (e.g., Puckman), I get the following error:
"Out of frequency range
Set resolution lower or see monitor guide"
I have a Compaq MV540 15" monitor.
I ran Fraggal's Mame Installer CD and chose Ensoniq sound card drivers, normal monitor (not tv or arcade monitor), and the Pentium I (i586) version of AdvanceMame.
Advice?
The monitor is set to 640x480 w/ a Vertical setting of 75Hz and a Horizontal of 37.6K, if that helps. Can't figure out how to change that setting in DOS...
