Individual Computers 4 player joystick adapter in a 3D printed shell

4 Player Adapter

Quite a few Commodore 64 games support 4 players playing simultaneously. The list includes:

  • Alone in the Green
  • Amazing Maze
  • Bombmania
  • Bomberland
  • Bugbomber
  • Garrison
  • Hockey Mania
  • IK+ Gold
  • Ivan ‘Ironman’ Stewart’s Super Off Road
  • Marble Madness
  • M.U.L.E.
  • Phong!
  • Quadris
  • Quadtron
  • Rampage Gold
  • Snacks 4 Snakes
  • Space Lords
  • Square Attack
  • Tanks 3000
  • Team Patrol
  • Tie Break
  • Tour de France 2005
  • Shotgun (link)

Individual Computers offers a solution that plugs into the User Port of the Commodore 64. However, the adapter looks like this when it comes from the German online shop:

It is therefore pretty hard (or near impossible!) to find a suitable case. A guy on MakerBot thingiverse.com came up with a solution and uploaded the 3D print files for a case for the 4 player adapter. The 3D print files are free to download. The files can then be sent to a 3D printing company like Shapeways. All I had to do to assemble the case was two small screws and I had a professional looking product. This is how the finished case looks like in black:

  1. Hi, this looks quite nice, although I have the opinion that the naming of Port 3 and 4 should be switched. I recently programmed a 4-player game (called “SHOTGUN” btw) and I’m quite sure that player 4 is controlled with the LEFT port, not with the right one (when seen from in front of the C64).
    Another question, how expensive was it to get this 3D printed?

  2. Hi ZeHa. You may be right about the ports being switched! I’m currently away from home but I’ll check it as soon as possible 🙂 I never even bothered evaluating the port numbers as I assumed the guy who did the 3D print model already did that – shame on me! Sounds great that you are doing a 4 player game for the commie! Any plans on uploading it to csdb.dk or something like that when finished?
    I payed like 19$ + shipping for the 3D printed case.

  3. Thanks for your reply! The game is already released on csdb 😉 check it out (link)
    I was (incorrectly) thinking that you are the creator of the 3D model, but in that case I will contact the original creator 🙂

  5. Thank you 🙂 Btw, I have talked to a guy who wants to print this for me, and now after researching a little further I think there are several versions in general. If you compare the Protovision version with the IComp version, you will see that the red board is a bit wider (the joy ports and the userport are farther away from each other) than the white board. I have the red version, and the 3D case was made for the white version – and of course, it could be, that the white version has swapped ports. So maybe I could be wrong about the port issue… (IComp-version and Protovision version)

  6. Shapeways is pretty expensive when it comes to 3D printing, so getting it printed elsewhere sounds like a good idea!
    I remember buying the adapter from IComp to make sure that the 3D print from Thingiverse would actually fit 😉 I’ll check which port is 3 and 4 this upcoming weekend and post my findings here 🙂

  7. I just tested it and you are absolutely right. Ports 3 and 4 have been swapped! Guess the guy on thingiverse didn’t double check everything before uploading – honest mistake 🙂
