Title: Flicker problem with ArcadeVGA
Post by: dth122 on March 02, 2003, 04:33:28 pm

I just revamped my whole system and am now running with a WG K7400 monitor and an ArcadeVGA card.  (I had a K7500 and Blade T64.)  I'm running ArcadeOS and DMAME 0.65.

Everything in DOS looks great, ArcadeOS looks great (but does not fill the whole height of the screen), but I get a ton of flicker when I run almost any game.  Also, the sizing for the vertical games is all off.  I copied the ArcadeVGA MAME.DAT file into my ArcadeOS directory.

Do I need to select resolutions for every game before I play it?  If so, when I go into the game config in ArcadeOS the only option I have is to hit Start 2 to close.

One other problem - I often get a lockup or repeating sound when I exit out of a game while it's playing audio.  I didn't have this problem w/ AdvMame.

Any ideas?

Thanks.

Check mame.cfg (in dmame's cfg directory) make sure that stretch is equal to 0, and there should be a setting in there keep aspect ratio, make sure that is set to one.

To see if it's a arcadeOS problem or a Dmame problem, launch a few games from the dos prompt and see if the problem still happens.

Also make sure you have scanlines turned off - scanlines will cause very bad flicker...
