I don't understand people's vents thing. Look at other types of carts, all 16 bit, n64, nes...no vents. AES uses the EXACT chips and has only aesthetic vents and no where near where the chips are. Solid state shit just doesn't run that hot. MVS carts have vents because they were designed to put in a wooden box mashed up against a bunch of other wooden boxes in an arcade. Even then the vents were pretty much there for the incredibly off chance that they were needed. Out of hundreds of mvs carts, I've only seen one KOF 2000 have a burned up chip and it probably had more to do with the mobo it was in than with ventilation. these shells are clearly for use outside of a cab and in a cmvs. Everyone stop worrying with the vents and just appreciate what shadowkn55 has made here. The guy clearly knows what he is doing with the Omega being proof enough.
