Commodore 64 and therefore TAC-2 only has one fire button so in MAME you have to use the SNES controllers buttons or keyboard for more buttons.In MAME this causes no issues whatsoever, but in Commodore 64 emulators this seems to be bit more tricky as I haven’t found a way to assign a gamepad button to each movement direction. Because I had to use the X-Y-A-B buttons for directions instead the original D-pad, I have to configure the directions as buttons inside emulators.A strange beast indeed! Can’t wait to try out some MAME games with this alien hybrid. So now I have TAC-2 & SNES USB controller. If I go to calibration the corresponding buttons light up when I move the TAC-2 around and also the SNES controller still works perfect. PERFECT! When I plug the controller in, it detects a generic game controller. No I’m not going to show what a crappy soldering job I did 😉 3. This way the added wires did not interfere with the SNES controller button presses. I drilled small hole next to each of the touch connectors and soldered the wires in place. Notice the circuit board is turned over and upside down in this picture. Here is an image of the locations I ended up using. I’m sure there is a way to use the D-pad buttons too, I’m just not electronically-inclined to know how. I also noticed that the SNES D-pad was wired completely different way so I had to use the four buttons on the right (A-B-X-Y) for directions and one the START buttons for my TAC-2. I decided to use this for my conversion so I didn’t have to unsolder anything.
After some testing here is the colors explained:Īfter opening the 5 screws that kept the SNES USB controller together I noticed free ground spot on the circuit board.
I cut the TAC-2 cable and found 5 smaller colored wires inside. I also stumbled upon this site which gave instructions how to salvage your old USB controller and use it to build a ATARI to USB adapter yourself! How cool is that! I didn’t pay much for the SNES USB controller so I decided I could use that one as a organ donor for my TAC-2 USB conversion. After more googling I found some DE-9 connector (also known as 9-pin ATARI) to USB chips so one could build an adapter for it. I was thinking how cool controller TAC-2 was and how I enjoyed playing games with it and how cool would it be if you could plug one to your PC. I also noticed I had 3 controllers for it, one beaten up TAC-2 and two other joysticks. Few more weeks went and I found my old Commodore 64C in the storage. I did some googling and found this SNES controller copy which connected via USB port so I could play SNES games with real SNES feeling. Everything was working perfect but my Logitech Rumblepad 2 wasn’t really cut for that job. Here is the story: After playing around with M.A.M.E.
