I have the zvg working with the windows beta setup! Clunky for now but I can play many games just fine. The brightness of the zvg is adjustable, so I can actually make the games brighter than "normal", I can see a difference right through the original Atari tinted glass. I have lots of "flickering" in various places in various games but I'm looking at a WG6100 and not a VGA CRT here. Irony is that this is the same rig I ran AAE, all the stuff is still there. I probably posted the specs months ago for AAE.
Main thing with the Windows beta is that none of the Sega games,Tomcat and Topgunner will not show on the game list/play, the vector menu isn't there and I am a complete noob with command line mame setups, so I can't even figure out how to rotate the vertical games yet and not certain the support has been built in yet. That's all "SteveJ"'s hard work, he is the genius here, I'm just an enduser and hopeful beta tester. My camera is busted but I'll take a few camera phone pics later.
And for the "purist" out there, Gravitar is still not quite perfect, even displayed on the same WG6100 in the Gravitar cabinet I have put this project into and never will be in any form of emulation when compared to running the real board, it just ain't the same. Space Duel, however is perfect and I just discovered the dip setting for 1 player only. More to come...
