ok so I may not need the arcadevga then. I just use windows and install soft 15khz and see if that works but your saying I need to run all that on normal monitor first and then switch to cabinet monitor once its applied??
Advancemame does that replace the windows operating system then as you mention why would I need windows if I have that installed.
Perhaps I should have brought a pre built system, that would have been easier but a hell of alot more expensive which is why I went down this route.
The pc im using has inbuilt graphics card not a removeable one if that makes any difference??
