Hey, I have one of those too. Mine is a SNK Kural 25" cabinet. I usually have a one slot installed. But I also have the CPS2 kick harness for the ocassional game of SF2/SF2CE and a ST-V harness for the Titan games. Nice setup.
I used to have a J-PAC on there with my old AMD K6-600 to run MAME but I got tired of it. Maybe sometime in the future.
