Check statusChecked Jul 30, 202664JPX JoyPad eXpanderby Nicholas Coplin / 64HDD

Safely translates Sega, NES, SNES, or legacy analog PC controllers for Commodore, Amiga, and Atari-style control ports.

The official page still displayed order instructions and prices from USD 14.95 for the chipless protection version through USD 36.95 for a combo interface with an adapter on 2026-07-30. However, its prominent post-COVID shipping notice and 2021 copyright are stale, and it says only that most items remain orderable. Contact 64HDD for exact version, stock, price, and postage before sending payment. SNES-to-JPX and PCanalog are companion adapters and remain in this product family.

Sold outChecked Jul 27, 2026ArcadeR Joystickby Commodore

Provides a microswitch joystick with a classic 9-pin plug and autofire for the Commodore 64 Ultimate.

The direct Commodore listing showed Beige, Black, Transparent Red, and Transparent Clear choices but was out of stock on 2026-07-27. The seller explicitly documents C64 Ultimate use but does not enumerate original C64 or other 9-pin systems, so no broader compatibility is inferred.

Build itChecked Jul 30, 2026C64 Joystick Switcherby tebl

Provides an open build for selecting either Commodore 64 control port from one Atari-style joystick, with optional second-fire and autofire circuits.

The repository supplies KiCad files, Gerbers, a schematic, bill of materials, and assembly guidance. Inspect the completed board for solder bridges and support it while pressing its buttons. Never move jumpers while powered or map two physical inputs to the same function. Do not connect a Sega Genesis or Mega Drive controller; the maker warns that it may damage the C64 and directs those controllers to the separate Mega Switcher.

Build itChecked Jul 30, 2026GenAssister V2by Evie Salomon / BackBit

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.

AvailableChecked Jul 30, 2026Nunchuk64by Robert Grasboeck (djtulan)

Converts two Wii Nunchuk or NES and SNES Classic Mini controllers into the two Commodore 64 control-port inputs.

Sordan exposed a current Buy route at EUR 30.99 excluding VAT on 2026-07-30. The maker also publishes KiCad files, Gerbers, firmware, assembly instructions, printable cases, and a GPL-3.0 license, and invites direct contact for DIY kits. Controllers and wireless receivers are separate. The guide's acrylic-case tile is an enclosure accessory and is folded into this hardware family.

AvailableChecked Jul 30, 2026Q36 Rapid Fire Modulatorby commodore4ever / Sven Petersen

Combines push-button Commodore 64 control-port selection with a dial-adjustable autofire rate.

The maker's store exposed an add-to-cart route at a USD 29.99 sale price, reduced from USD 39.99, on 2026-07-30. The public description identifies the C64 but does not publish broader host compatibility, complete signal handling, or an installation manual.

Build itChecked Jul 30, 2026SNES Controller to Atari/Commodore Adapterby raphnet

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.

Check statusChecked Jul 30, 2026TOM USB HID Adapter Familyby Electronica4u

Connects USB HID mice, keyboards, joysticks, and gamepads to Commodore, Amiga, and Atari ST-family control ports.

Sordan hosts current Rev3 and Micro Tom pages and a Rev3 manual, but neither product page exposed a price, stock value, or product-specific cart route on 2026-07-30. AMI64 listed TOM 2+ at GBP 40 but out of stock. TOM+ and TOM Rev2 are retained as older variants rather than presumed current products. USB peripherals may be hot-plugged, but the DB9 adapter must be connected only while the old computer is powered off. Device compatibility is not universal.

AvailableChecked Jul 30, 2026ZGCS Joystick Port Switcherby ZGCS

Adds push-button or controller-triggered port swapping plus four selectable autofire rates to a Commodore 64.

Tindie showed two units in stock at USD 34 on 2026-07-30. Remote swapping requires modifying a controller with two diodes and a button, or rewiring an existing button. Mouse operation is only an untested seller expectation; the documented analog support covers paddles, gamepads, and two-button joysticks.
