GroovyMame - ArcadeVGA3000 - “could not find a video mode"

[darryldale]

OK, so I got finished putting my first Hyperspin cabinet together and it ran flawlessly using an LED monitor.

Decided I wanted something more authentic so picked up a Mortal Kombat Cabinet that is now setup as a Mame/Hyperspin machine.

On to my problem. Config:

Mortal Kombat Cabinet
WindowsXP
ArcadeVGA 3000 Card running into J-Pac
K7000 15khz Monitor

It has the ArcadeVGA 3000 drivers installed and the desktop is running at an interlace 640x480.

I can launch Hyperspin and it runs fine.

I took my Hyperspin folder and deleted my mame.ini file and replaced my normal mame (v160) with the groovy mame (v160) executable.

I ran it with the -cc parameter to create my ini file.

The ONLY change I then made to the file is I replaced the generic_15 line with arcade_15

If I launch the normal mame.exe it will come up. If I launch the groovy mame executable I get the following message:

“switchres: could not find a video mode that meets your specs.”

Any ideas what it could be?

OK, so a little searching and I came across the following two settings that need to be set for the AVGA:

refresh_dont_care 1
lock_system_modes 0

That at least got me up and running with the groovy mame executable.

Now on to the next issue.

If I launch the old mame executable and generate a log while running MK3 I can see that it creates a direct3d screen at what appears to be 640x480. This looks pretty good on my monitor with no flicker or anything.

If I launch the new groovy mame and run MK3 it appears to select a resolution / frequency very close to what the info screen shows for MK3 but I get a flickering / wave on the monitor.

I would guess that maybe my monitor can't quite handle the frequency / resolution that is being piped to it by the AVGA?

MK runs at 54 Hz, try adjusting both h-freq and v-freq pots.
