Soft-15KHz - slim new tool for 15KHz on normal vga cards
Eversynth:
Hi everyone!
Premise: A couple of years ago I did set up an arcade PC. The first time I used an ATI X1950Pro, but it turned out sub-optimal as it didn't work well with low resolutions. I also had to drive 2 TVs, so I ended up purchasing 2 ATI 9250 PCI.
BUT the 9250 PCI only supports up to Directx 8.1, and they are really inadequate for anything besides DOS and Emulation. I don't want to run advanced games, but even simple games require at least Directx 9.
NOW: I would like to purchase a recent card(s), one that supports REAL 320x240 resolutions, like the hd4350 and hd4550 can.
THE PROBLEM: Where I live the hd4550 is not readily available. (Too old?)
The question: Are there any other cards that fully support low resolutions out of the box, like the hd4350 and hd4550? In the official thread about supported cards on arcadeinfo.de only the hd4350 is mentioned...
If anyone can help me it will be appreciated. :notworthy:

I need some help with this thing...
I have a Geforce 7600GT running in Windows XP SP2 and I am trying to get this thing to work with my Wells Gardner 19K4901.
So I was using the standard Geforce drivers when i first attempted. and I could not get anything to work. So I installed forceware 169 and then reinstalled the soft15khz.
I rebooted the machine and I had all of the resolutions available from 200 something to 1024x768 all at 32bit. but if I select the resolution of 640x480 i get no picture, but if I select the native res of my LCD i get a non-synced desktop on the Arcade monitor.
Now here is another strange thing. If I turn the machine on with the LCD and the Monitor plugged in, I see the POST and BIOS, at 31khz of course so its just scrolling around, but its there...
If I unplug the LCD from the DVI port, I will not get any video at all on the arcade monitor, not even POST or BIOS.
Any ideas??? I have been reading as much as I can find on this thing, but I have no ideas and im about to throw this thing off my balcony...

Use the DVI port for 15khz once you disconnect your lcd

I tried that, using a DVI to VGA adaptor with the CGA to VGA adapter I created. Pins 1-3 are RGB pins 5,6,7,8,10 are ground pins 13-14 are H and V sync. I followed the VGA pinout from ultrimarc.
So should I install the forceware drivers, reboot, install sync15khz, change resolution to 640x480, shutdown, unhook LCD from DVI and plugin CGA to DVI with the adapter?
Would there be any reason why I wont even get the POST or BIOS with just the CGA connected to either VGA or DVI?
