Tag: controller adapter

Safely connects a Sega Mega Drive or Genesis controller to a Commodore 64, Commodore 128, or Amiga with configurable fire and jump mappings.

The open CERN OHL 1.2 project supplies design and fabrication files plus a bare-PCB ordering route. On 2026-07-30, Gotek Retro listed its assembled C64/128 and Amiga adapter at EUR 15 and AMI64 listed its assembled C64 and Amiga adapter at GBP 20. Turn the computer off before changing selectors, choose the correct computer mode, and assign each function only once. The open and AMI64 versions may need a joystick extension cable at an Amiga 600.

Converts a Super Nintendo controller into Atari-style direction and fire signals for tested Commodore, Amiga, and Atari computers.

This is a build project rather than a current assembled product. Use the published Atari/Commodore wiring, ground PB1 to select that mode, and program the ATmega8A with the documented firmware and fuse bytes. The maker reports successful tests on a C64, Amiga 500, Amiga 600, and Atari 130XE; the 130XE relationship is banked because that exact target is not yet in the catalog. Minimig and Amiga CD32 are explicitly unsupported.
