Hi, I'm using a Radeon 3870 hooked up to a Wells Gardner 25K7191 and I'm currently unable to find decent settings for VMMaker to produce a working range this monitor accepts. I'm testing settings in ArcadeOSD and have found that the preset for H9110 produces the most working modelines for this monitor. But none of the lower res modes are working - basically anything under 328 x 256 @ 60p, which rules out a lot of the MAME library.
I know this was a popular monitor found in a lot of cabs so I figured I would ask here if anyone has nailed a preset for VMMaker/GroovyMAME.
