Yes, I know that. I don't think you're getting my point. Rather than making a microcontroller to wire to the Jamma, since the NG AES controllers have designated pins per command you can just add a DB-15 male and take each comman and wire it to the Jamma board. Only thing is I need 2 more buttons because I will be using these on Capcom fighting games and I want to make a converter like some candy cabs have and let you plug in your psx controller. Thanx.
-See Ya!!!
