I too have tried Gogo Ackman's latest FBAX-XXX, and I really like the new features: Autoload Uni Bios vers 1.3, Push righ thumb stick to fast forward in games, Overclock 12 to 18mhz in Neogeo games, Seperate menus for CPS1/2 and Neogeo, fixed CPS 1 to CPS 2 and back and Ghouls & Ghosts sound works!! Thats the one game I have that in the past vers of FBAX there was no sound. I run my Xbox through an Infocus X1 DLP projector from my Xbox's Progressive scan MS tHc Dashboard in 480P.. As for SNk vs Capcom:Chaos, it my be a wrogn p1 rom or wrong loaded Neogeo bios I'm using the SvC:Chaose Plus (Bootleg) version that has the vs menue with all the bosses opened up as selectable.
