Strange issue with GroovyMame v.146

Hi mamenewb100,
Why would you want to install drivers for the video card? Everything you need is already in the CD.

Didn't know that it included AVGA drivers. That is cool.
Still haven't found out how to get my arcade monitor to display without going out-of-range. I think it's still trying to run at max res of the vid card even though I picked 640x480 in GA setup. The vid card is feeding a 48 Khz signal and I'll google later to find how to change resolution in Linux. Hopefully that fixes it.
I was able to boot directly to the frontend so I could at least test to see how it looks. I noticed that the graphics looked a little more pixelated probably due to doubling the pixels. However the colors are more vibrant and characters look slightly bigger/better. It seems that the inconsistent game speed is fixed. However some games like Pacman and Donkey Kong are running very slow like they are in PAL mode or something. Overall I like it if I can only get my other PC working with it and fix the display issue.

So where exactly are you getting an out of range resolution? Is it during boot, during GA setup, both? You'll probably need to define a proper modeline in xorg.conf that fits your monitor. This will need to be done manually, I'm afraid. Hopefully the Linux guys can give you a more helpful answer.

So the frontend runs at a proper resolution?
Pixelated graphics may indicate the scaling is working. I'm concerned about the vertical games, those should run fine at their right speed. Please get me a log of one of them, I'll figure out what's the issue:
groovymame romname -v -md 4 >romname.txt

Pacman runs slightly slow on my setup and you can hear it in the audio, but that's a side effect of the SoundSync code.

Funny that I spent all that time on xorg.conf only to find out xorg is the program that runs the emulators. Xorg is not the problem, it is the Arch Linux shell at boot that won't allow change to it's resolution. It always defaults to 1440x900 resolution. Once frontend starts then res changes. I don't understand why xorg can't run the whole time. That way there wouldn't be a problem.
