So.. this is a crosspost from the monitor forum... but i know the monitor works (because it's beautiful hooked up to my tekken 3 PCB)..
I know my Groovymame setup works, because it's beautiful hooked up to my RGB modded 27-KV300 Trinitron..
So I'm thinking this might be a groovymame/vmmaker issue. Here's what's happening with my K7000a I just repaired:
So I wired up a vga breakout cable and hooked it up.
I’m getting the following running TMNT forcing -resolution 320x240 out of groovymame.
This is with hsync and vsync both wires up to the hsync- and vsync- terminals on the chassis respectively. Any suggestions?
