i plan on using it mainly to play mame with kaillera. i play alot of online mk2 and i figured it would be more nostalgic playing someone i didnt know using a cab . but i want the other emus there just because the cpu im buying will hold them and i wont feel justified not being able to play any game i dream of after paying 600 bucks for a cpu. so basically i want the cab ready for any game i want incase i get the urge to play sega snes psx ect..and i want a ps2 controller plugged in via usb at all times just incase im not wanting to stand there and use a joystick.
