add new modelines for arcadevga?
manman:
Thanks a lot for the help guys, I really appreciate it. I guess i'll let my system keep being a guinea pig to test this out, but I'll proceed more carefully from here on out...

Ok, so I was able to fix that problem and get a compatible signal again, I just have a question about the modelines I tried to use. From the "useful modelines" guide that came with it I tried to install the following:
Modeline "304x224 NTSC (60Hz)" 6.365 304 319 349 405 224 236 239 262 -hsync -vsync
Modeline "384x224 NTSC (60Hz)" 8.040 384 403 440 511 224 236 239 262 -hsync -vsync
(although, once added + reboot, they show as)
Modeline "384x224_60 15.7KHz 60.1Hz" 8.040 384 403 440 511 224 236 239 262 -hsync -vsync
Modeline "304x224_60 15.7KHz 59.9Hz" 6.360 304 319 349 405 224 236 239 262 -hsync -vsync
I'm just wondering if there's anything obviously wrong that jumps out from that, or if the modelines are fine and it just points the program not being compatible with my card? Winmodelines seems to recognize my card as an "arcadevga 3000" just fine and shows status: OK, but whenever I test those resolutions I just get a blank screen. The other 15kHz resolutions that were pre-installed with the card look fine.
One thing to note- i'm not sure if this matters. I've only tested these while hooked up to my LCD monitor via DVI. The card's instructions say that if you want to hook up a computer monitor you have to use the dvi port. When I hook up to my arcade monitor of course, I use VGA. For the built in 15kHz resolutions I can see them fine with DVI, but I don't know if that would make a difference for the modelines added via winmodelines?
Thanks

Hi manman,
From the modeline's text string between quotations, only relevant parts are xres, yres, vfreq, which are used as a label for the modeline in the registry, the rest is ignored, that's why you don't see "NTSC" in the modeline after reboot, but your modeline is ok. If your getting a blank screen then it's probably working, but you will only be able to see that mode on a arcade monitor or tv. If you are able to see the built-in modes on LCD it's because your card is prepared for dynamically selecting a 31KHz signal for those modes when it detects a LCD/PC monitor. But that does not seem to happen with new modelines added. Anyway, it's interesting to know.

Thanks for the info, I guess I'll try it on the arcade monitor and report back on how it works.

Sorry for posting on an old thread but I need some help. I foolishly tried to use winmodeline to add a better modeline for mortal kombat on my arcadevga 3000. upon reboot my screen is blank. so I tried to boot in vga mode and change the resolution to 640x480 32 bit. when I try this however the computer just crashes and I get more of the same. any Ideas? thanks guys.
