I'm building a second GroovyMAME + Attract Mode + CRT Emudriver set-up for a new cab I bought, a New Net City that has a lovely tri-sync screen.
I have everything up and working well as per Calamity's guide, but when I install the tri-sync drivers (i.e. rather than the standard 15khz setting), while GroovyMame works exactly as it should, and games look good etc, the PC desktop/ menu screens become totally squashed and unreadable.
Is there any way to fix this, as it currently makes running the set-up at 31khz unworkable?
