Description

SNES controller adapter for Atari 2600 (DB9)

I designed this adapter primarily for my game - Berta and Butterflies. I wanted to make controlling experience more similiar to the "Game & Watch" consoles and be able to move the character to any corner using only one button.

However, the adapter has also a different mode. You can switch the mode by pressing Start+Select at the same time. In this mode it will work as a normal adapter. It means that the arrow keys will work as joystick directions and "Y" button as fire.

Parts list:

IC1 - Atmega8, Atmega48 or Atmega88 microprocessor

R1 - 10kOhm

C1 - 100nF

X1 - female DB9 connector

U1 - SNES controller socket
