To make this short since this is the second time typing this out, I socketed the Z80 sync bus controller daughter card on my Gallag board backwards while simultaneously plugging the main board in backward at the harness as well. Ive been kicking myself for 3 weeks over this.
It was totally dead (no picture) until I replaced all but one IC on the Z80 sync bus, and now the game comes up like this:
http://www.youtube.com/v/M9XM9lzhfHo&hl=en&fs=1It wont boot at all without the galaga enhancement pack installed, but It can be played perfectly fine, its just hard to see.
How do I go about trouble shooting the video problem? All the info I can find is a poorly scanned set of schematics that has a page missing.
BTW: the green in the monitor is a problem Ive been having for a couple years even with the game running fine. I did plug in a different game and It came up perfectly fine.
