In Reply to: Anyone have probs using mame on arcade monitor in 16-bit? posted by Jon Wright on August 18, 1999 at 20:08:10:
: I've only just downloaded the lastest mame beta, for use in my mame cabinet however when using certain NeoGeo games eg KOF, Neo Turf Masters in 16-bit colour I get only one half on the image displayed which has been stretched to fill the screen.
: Does this happen to anyone else and can it be cured????
This looks like a 'tweak' problem. MAME sets the VGA registers to draw video in a way compatable with arcade monitors(called tweaking). Since not all video cards respond the same way, this doesn't always work. Manual adjustments can be made in the MAME.CFG file for standard video modes, but I don't know if you can change the arcade mode.
I have the same problem on a standard monitor with the default settings.
