GroovyArcade Frontend Resolution

[Jollywest]

I've recently successfully installed GA onto a USB Flash Drive, and I'm using it on a ATI HD4350/JPAC/Hantarex Polo 1 25" setup.
GM is working great, running the sample roms at their native refresh rates.
The Frontend however, be it either ADVmenuPLUS or Wah!Cade is running at 640x480 interlaced and I can't seem to alter this to a non-interlaced resolution.
When I run $ xrandr from a terminal window the only selectable mode is 640x480.
Any ideas please?

The resolution these frontends are using is controlled by a modeline that's inside the xorg.conf file. Try editing that file and add another one as you like. Then it's a matter of setting up advmenu to use it.

Spot on Calamity, got it working... cheers!  ... as you can probably tell, I'm very much a Linux newb

These are the two modeline I am using to accommodate X screen resolution.

Jolly can you show your xorg.conf file text

I'd like to get my groovy arcade front end running in a native arcade resolution.

Which arcade native resolution do we think will look the best?
TY!!

Not sure which resolution is best yet, I'm just using 320 x 240 @ 54 for testing at the min.

I'm using Wah!cade as the frontend and had to knock up a quick custom 320 x 240 layout with the editor, as none of the layouts that came bundled with Wah!cade showed properly at that resolution.

Just out the house at the mo, but will post the xorg.conf file when I get back.

Here's what's in the Xorg.conf file;

All I did was add a 320x240 modeline at the bottom and put a hash in front of the 640x480 one.
To revert back to 640x480 just remove the hash.

This is for a Hantarex Polo 1 25" arcade monitor.
