I have a arcade cab setup, with multiple controls. Whenever I start Project Justice in DEmul for NAOMI, not Dreamcast, I get a PORT B VMU icon, and game plays as normal, except that when I get hit or otherwise, my player 1 XBOX 360 controller vibrates. I cant figure out why. I use my X360 controllers for Dreamcast, but not NAOMI. Also, why is this the only NAOMI game that opens a VMU? Thanks for any help you can provide.
