![]() ![]() Some games like Twinbee will treat player 1 and 2 in expansion port as player 3 and 4. Some games will treat the 2 extra controller as player 1 and 2, same as built in controllers. If another 7402 does not change, probably faulty capacitor?įor Famicom only: not all games will support extra controllers on expansion port. If there's no pulse or only 1 side, try a different 7402. If you have access to logic probe, check pin 2 and 12 to see if button C and D is getting through, then 1 and 13 to see if you got pulsed output when the button is pressed. Check for solder shorts, incomplete or cold solder, and for stray solder blob or bits of wire on the PCB.Ĭontroller works but rapid fire doesn't work? Make sure that 7402 is CMOS friendly version. test Neo Geo controller to ensure it is not defective. The board can then be screwed or snapped into the standoff.Ĭontroller doesn't work at all? Check that you wired the cable for NES or Famicom correctly, use an IC tester on 4021 if you can. I intended to use plastic standoff and glue one end to the bottom of the box after I make the necessary cutout for Neo Geo controller port on one side and small opening for the cable(s) on other side. It should fit most project boxes whose inside dimension is bigger. Make sure there's no stray strand of wire sticking out.īefore plugging the adapter board into NES or Famicom console, using meter check the resistance between VCC and GND to ensure there's no short.įinished 2P PCB is 3.40 x 3.20 inches (86.5 x 81.4mm) and 1P PCB is 3.40 x 1.85 inches (86.5 x 47.1mm). When you find all 7 wires you need, cut off the unused wires and tape it off or use heatshrink to seal it in. To make checking with a meter easier, I would use the 15 pin male connector before it's soldered on the PCB and use that to probe the pins to wires. Using the handy pinout guide, find which wire goes to which pins, be aware the female end pin numbering is reverse of male pin numbering. Solder wires according to the pinout, one cable to NES1 on top, and second cable to NES2 on bottom.įor Famicom consoles, I would use Neo Geo or Atari 5200 extension cable and cut off leaving enough at female end to work with. Cut off or tape off unneeded wires (make sure no stray strand of wire would touch anything) or use heatshrink over it. The top silkscreen in the middle of the PCB has handy pinout guide. Strip the exposed wires, use meter to find which pin goes to which wire. ![]() If you do not have the equipment or the soldering experience, I find a 6-pack of quality beer would be enough to get a friend to help with the project.Īssemble parts by matching the parts from bill of material (BOM) with the silkscreen and solder them on.įor NES cable, I'd use the NES extension cable and cut off one end, be sure the plug that goes into NES deck has enough length of wires that you can work with. I used all larger through hole components for easier soldering. Requirement: multi-meter (in OHMs setting), soldering iron, wire cutter, and wire strippers, and have some soldering experience. This adapter will not work with Neo Geo mini controller!! A and B may seems backward but this is how NES and Famicom controller is laid: B and A I've included pictures of 3 Neo Geo controllers and the button mapping. * 1x NES and/or 1x Neo Geo/Atari 5200 controller extension cableĬontroller button mapping are: Neo Geo A to NES B, Neo Geo B to NES A, Neo Geo C to NES turbo B, and Neo Geo D to NES turbo A. * IC3, IC4 74HCT02N DIP IC (some general TTL may not work correctly, needs to be a CMOS friendly version) * 2x NES and/or 1x Neo Geo/Atari 5200 controller extension cable If you do not wish to have rapid fire circuit, you can omit the "optional rapid fire circuit" listed below. BOM: (all parts are through hole for easier soldering)
