Okay, what did I do wrong?

: Finally got the time to piece together my MAME cab and the blasted thing doesn't work. It just gives me a blue rolling screen and a high pitched squeal. This is the way I have the VGA-to-JAMMA wired up: : VGA pin 1 (Red) -> JAMMA pin 12 (Red) : VGA pin 2 (Green) -> JAMMA pin N (Green) : VGA pin 3 (Blue) -> JAMMA pin 13 (Blue) : VGA pin 6 (Ground) -> JAMMA pin 14 (Ground) : VGA pin 7 (Ground) -> JAMMA pin 14 (Ground) : VGA pin 8 (Ground) -> JAMMA pin 14 (Ground) : VGA pin 10 (Ground) -> JAMMA pin 14 (Ground) : VGA pin 13 (H.Sync) -> JAMMA pin P (C.Sync) : VGA pin 14 (V.Sync) -> JAMMA pin P (C.Sync) : I have the H.Sync and V.Sync wires twisted together to get a composite sync signal. I've checked continuity and there are no cold joints. I'm using a Trident 9880 Blade3D video card and a standard res monitor (15.75KHz). My AUTOEXEC.BAT runs BLADETSR.EXE (no parameters) at startup and I have MSDOS.SYS set to BOOTGUI=0. I've also tried BLADETSR.EXE -E, but that didn't work either. : What am I overlooking or doing wrong? : Thanks, : Mark
