Just for fun, last night, I tried running CVGS under Fusion and it worked! I only tested it briefly with Final Fantasy VII, but I did manage to play for about 10 minutes before deciding to hit the sack.
To get it working, you must turn off "Accelerate 3D Graphics" and only use one core. To get it working in Windows XP, look for SaPu's patch. It allows CVGS to work in XP and with Pentium 4s among other things.
