Hi msingleton1977,

You don't need to use the "CUSTOM" keyword inside mame.ini, that one is for vmmaker which you're not going to use. So just leave the default there and paste the right monitor_specs lines.

Now in order to know what's going on I need you to post a log here, type this:

groovymame.exe popeye -v -md 4 >popeye.txt

and attach the file here, that will show us what resolution is being used.

msingleton1977:
Thanks for the prompt response Calamity.

I changed MAME.INI back to the default which was CGA. Is that the correct setting for a Tri-Mode monitor? I left the monitor_specs lines with the settings for  NANAO MS-2930/MS-2931. Still no change.

I’ve attached popeye.txt.

It jitters almost like the vhold pot isn’t set right but this isn’t the case. I’ve tried adjusting it and it doesn’t fix it. Also, Street Fighter 2 CE looks perfect and I believe they are both 15khz games.

Calamity:
It's picking the right resolution: 512x448, that should be fine for your monitor. Could you check this resolution with Arcade_OSD to see if it works?

msingleton1977:
I checked the resolution with Arcade_OSD and 512x448 @ 59hz is shaky and un-usable. However, if I move to 512x384 @59hz it looks great.  Any ideas? Scrolling through all the resolutions some display properly and some are shaky or blurry.

Also, all the Vfreq’s are either 59hz or 60hz. Shouldn’t there be some 15hz or 30hz since it’s a Tri-Sync monitor? How do does the PIXES x PIXELS number work with the Vfreq rate?

Thanks,
Monty

Shaky resolutions might require monitor adjustment to get a stable picture.

Is your monitor connected to the VGA port on the ArcadeVGA?  The DVI port is for PC monitors only.

Are you sure that the Ultimarc tri-sync utility installed properly?

Can you select 15KHz resolutions using the quickres (galaga) icon in the system tray?
