I got a MV-1B the most compact of all 1 slots, u just need to install a unbios to get rid of the track ball bios, Ill let it go cheap too. under $100 bucks. $75 shipped and everything, the only thing is it has been used and it has scuffs and scratches where the carts go, obviously because of alot of use. I can show pics of it working and everything. It will only gost $55 to get the unibios installed from JMKurtz, add $10 for a pause button. Let me know if not SNK FOREVER.
