I have a JPAC on it's way to my house, and I'm going to finally set my JAMMA cabinet up for MAME. Now here is the question as I have both available: Do I use a spare PC that I have lying around, or do I just use a spare xbox that already has MAME installed on it. Right now I plan to use the existing arcade monitor, but if that ultimately proves to be too much of a hassle I would consider ripping it out and replacing with a spare TV or VGA monitor as required.
The PC would require me to set it up in the first place, and then verify the video card supports 15kHz or else get one of the software solutions to do it. The Xbox would require me to buy the controller adapter and video adapter from Ultimarc, and probably be a little simpler.
Thoughts or experience either way?
