PLEASE MOVE TO SOFTWARE
Ok.....I've got everything working great on the avga and arcade monitor....most games work without changing settings...but some games like spyhunter, tapper and such are getting screen flicker ( refresh rate I'm guessing ) just using mame32 for testing right now, well actually I just like looking at the games...they look so nice now :) what setting should I change so they display correctly....I want them to display vertically and correct orientation....it will be in a cocktail eventually......I will migrate to mamewah and command line mame when i get there.......would appreciate any advice...currently running windows xp and have the resolution at 640x288 16bit.....need to get panning working though......
thanks all

In display properties in Mame32 under the advanced tab what settings are you running?.
-
I'm not at home at the moment so I'm not sure....I tried alot of different combos, but probably didn't try the right one.....if someone could just give me their spy hunter or tapper....I can probably work from there.....regardless....I'll post the setup tonite when I get home...

IIRC those games run @ refresh of 30Hz interlaced or something like that. I wonder if that's why they are behaving that way. I do remember someone else having an issue w/ Spy Hunter and got it going. Search the forum archives, it might turn up there.

Yup, Spy Hunter, Tapper, Rampage, etc all use low-res background graphics, with high-res sprites. So there's something special about the display for those games...
-
Yep...I read the 30hz thing in their descriptions......but I ain't got no 30hz....lol

Bally Midway games that ran on the MCR boardset (Tapper, Tron, Kick/Kickman, Satan's Hollow, Spy Hunter, etc...) all output video at a vastly different rate than most all other games.
(Assuming vertical orientation) they run at 480x512 at 30 Hz, Interlace mode. Where most other Bally/Midway and most others run at 224x256 at 60.60 Hz, non-interlace.
Even if you can get them to work on the arcade monitor without them rolling or tearing, they will "jump" and be hard on your eyes due to the interlacing.
Most newer monitors and the replacement chassis don't support refreshes below 48 (48-65 usually) so they won't be able to draw the interlace modes.
About the only thing you can do is use Advance Mame and tell it to chop the resolution down and use a non-interlace mode. But since you're using AVGA and Mamem32, you may not be able to select a more compatible mode.

I got mine setup for 47hz for the 30hz games.
Tapper, Rampage, Journey, Blasted etc... is a 512x480x30hz and I run this at 512x275x47hz.

MonitorGuru,
Can you elaborate on this 30Hz, I've put a CGA compatible LCD in my Spy Hunter arcade cabinet, and I get a very dark and blurry picture. Is there a scan converter or some other device that I can use to convert this 30Hz to 60Hz that my LCD can understand? I really want to get it working!

but some games like spyhunter, tapper and such are getting screen flicker
Have you tried manually setting the resolution to 640x480? The AVGA will automatically interlace this resolution (unless you installed the multisync patch). Spy Hunter and Tapper used to look perfect on my CGA arcade monitor at those resolutions. I don't recall any flicker at all.
