Connects one six-button Sega Mega Drive or Genesis controller to both C64 or C128 control ports with port switching and extra button mappings.

BackBit says it no longer has capacity to build this former product and has released the design under GPL-3.0. The repository supplies KiCad board and schematic files, CUPL source, printable case files, and a bill of materials; a build also needs the listed ATF1502 CPLD and an ATDH1150USB programmer. The former store URL returned 404 twice, including after the required 60-second retry.

Replaces the circuit board in an original or reproduction NES controller so it works as a Commodore 64 gamepad.

AutumnHippo exposed an add-to-cart route with a USD 8 base price on 2026-07-30. The page offers a bare PCB, a kit with a reproduction case, and a fully assembled controller, but it does not expose every option price in extracted text. A bare-board build needs a case, a correctly traced cable, a switch or solder bridge, and basic soldering. The maker also states generic Amiga and Atari computer compatibility, but exact model relationships are not attached without model-specific evidence.

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.
