Because i lack the space for another cab (apart from my centipede) im building a small jamma rig to play some boards on my tv set. I have some ATX psu's lying around i wanted to use, however they all lack a white -5v line. Would most boards work without this -5v? I noticed some systems like Atomiswave not even requiring one anymore, would my arkanoid/turtles/final fight work without one or shouldnt i even bother trying
