This board can be used to replace the interface board in your Mega Drive/Genesis Retro Joystick Kit or it could be used to build your own 3 button Megad Drive/Genesis compatible joystick.

I Purchased this adapter to replace a project where I was using a modified original controller. Unfortunately that original controller died on me. But this adapter was a easy no fuss solution, and freed up a lot of space inside my project box! I have been using this adapter for about a year and a half with no issues.
