I have a SNES w a jamma adapter for sale.
Just connected it to my jamma cab and the video tested ok. Controls and start button were not working from the jamma cab adapter but worked when I connected a joystick to the snes. MOunted on thisck clear plexi. This can be rewired to correct this either from the adpater or hacking a snes controller board. The jamma board has adjustment pots for video which work and a 2 other adjustment pots that I dont know what they are for. Sound was not working when tested. Online they say that you might need a sound amp for this. Not sure. I dont have the time to deal with figuring this out but told by the operator that I got it from that it works fine. Has 16 dip switches that I have no idea what they do. Game registers coins and the reset/on/off switch tested ok. Giver your best offer, highest offer will get it. Includes buster bros cart
