Simple PCB + ATTiny404 code for a 6-button mega drive controller.
This is a KiCad project for a board and accompanying ATTiny404 code to implement a replacement for the custom chip in the 6-button mega drive/genesis controller.
Note: the main HEAD is not necessarily tested! Tested revisions of the board+firmware will be tagged
Latest tested fab here: https://oshpark.com/shared_projects/aK2wBkfg
Currently there is a 14-pin dual row header used for the buttons because I was unaware of the brook 20 pin header at the time. I might add that pinout to future boards.
