In Reply to: Mame to Arcade monitor question posted by StLouisRod on 22, 2001 at 2:33 PM:
I forgot to mention that I'm using a newly purchased ATI Expert98 PCI video card. I'm also having a problem with the interlaced 640x480 mode. Once the mode is set, usually the entire screen (or just the lower half sometimes) is jittering up and down due to the interlaced horizontal lines being off by one or two lines! It's like the beam is getting off track at a certain point. How can I fix this within the video modeline config parameters? Which value should I monkey with?
Having hooked up Mame to my standard resolution 26" Wells-Gardner monitor using the J-Pac converter, I was able to get nice images using the standard_320x240 and standard_640x480 video drivers within AdvanceMame configuration. However, when I attempt to test any modes other then those 2, I get a completely unstable and garbled screen. Some modes actually force me to reboot my PC! Is this common, or am I missing something in my config files? I've been using ADVV to test various video modes. I noticed that in many of the pre-created standard video config files for standard res monitors, there are many different possible resolutions (modeline statements) within them. So why can't *I* get these modes to work? By the way, I've set my hclock to 15.75, vclock to 50-60, and pclock to 6.75. This was set by the ADVCFG program after telling it I had a standard res arcade monitor. Thanks for any help!
