Maybe this might not be considered as worthy as fixing up my home, but I repaired a Dual Joystick I bought used yesterday. It turns out the motherboard had gone bad, and I had to use the mobo and the serial&PS/2 cable patch from an kit I was going to use to upgrade my HanaHo HotRod joystick.
The controller now works BETTER than my HanaHo ever did, and now I have USB support.
Why do I think it’s worthwhile? My daughter still remembers that I set up arcade emulation to stop her from feeding tokens to the “Teenage Mutant Ninja Turtles 2: Turtles In Time” cab that used to be at our local Chuck E. Cheese’s. We played it all the way through today.
