Dear all,
Tomorrow I'm planning to start the woodworking side of my cabinet, so in preparation I checked the final dimensions that I needed - the motherboard and cards. However, due to the fact that I'm making a bartop cab, the AGP and ISA cards sticking out of my motherboard, it won't fit. I don't really want to increase the cab's size, so I am trying to get another motherboard up and running instead.
This is the problem: using the TNT2 M64 card in the other box, I had every screenmode set up perfectly (I'm using an NEC3D monitor, which does 15.5kHz modes, so it's great). However, the Jetway 920BF motherboard that I'm hoping to use won't cooperate. It has an SIS 6326 VGA chip, which I'm fearing is the cause of my problem.
The issue is that most of the screenmodes are too tall to display on the screen - only the top half is shown. The issue is with pretty much every screenmode of use for emulating early to mid-1980s machines - only VGA (and higher) resolutions are fine. The monitor can handle the screenmodes, as with the TNT2 card there isn't an issue. I've tried playing around with about every setting I can find in the advv config tool.
Any ideas? Do I need to make a larger cabinet (not going to get another motherborad with onboard graphics_, or am I just mucking up something?

I have a sis6326 and it does exactly the same thing.
What you have to do is to double the vertical resolution for all games with <300 lines. Advmame will automaticly scale the picture so there is no visible difference in the display.
in advmame.rc

WPCMAME, thanks for your suggestion. Is emulation speed affected? I ask as the Celeron 433 I'd use with this motherboard doesn't exactly set the world on fire...
