For quick and easy installation of longhorn engineer AV mod. Tested and it works great.

This is a revision of the Neo Geo controller to Atari 2600 adapter. This one is revised to use through hole ports. I added text to note that the board will also work with the Sega Mastersystem. 2 buttons will act as fire on Atari. On the SMS 2 buttons will act as Button 1 and the other 2 buttons will act as Button 2. As with the original design the console will have to be moded with an external jack to bring Reset and Select external to connect to the header of the board. External 5v and GND are probably not necessary and were added in the off chance that the Atari 2600 doesn’t output enough power to power a more advanced Neo Geo Joystick. Most Neo Geo controllers don’t require power at all. I have yet to test this board, however it is based on a hand wired version that works fine.

Neo Geo to Atari 2600 Controller adapter with Select and Start Header. With modification to your Atari console Select and Start on the controller can serve as Select and Reset. The Start and Select button on the Neo Geo controller are on the header, as well as external power and ground. External power and ground is not necessary for normal controllers and may only be needed if the Atari can’t power more advanced Neo Geo joysticks and controller adapters. A connector will have to be added to your Atari 2600 to bring Reset and Select external to the system to connect to the header on the board. This is intended for use with wires and panel mount ports. I have yet to test this board, however it is based on a hand wired version that works fine.
