VF1 worked fine just with minor stuttering in R5 but when i upgraded to R6, VF1 froze either at the Rom Check screen or 3+ secs into the intro, freezing at the Kage v. Sarah fight in the intro. Im running Xbox v1.1 with a Xecuter 2.2 Lite, UnleashX, and EvoX M8+ as my bios. I havent looked into any other game atm.
