currently working for me are the following systems CPS 1/2/3 outrun/afterburner system 16 (altered beast etc) neogeo taitoz (chase hq, SCI) know system that does not work is rtype games. some sytems also have control problems ie operation wolf power drift heavy barrel as for geting sf3 working you need the latest mame compatible version. I would also recomend overclocking otherwise it will have a bad framerate. At 1.15 it runs well.
It does support CPS3, I just got Street Fighter 3 Third Strike running! Overclocked to 805MHz it is still a little slow, but working.
