I don't know how you handle the output pins on your microcontroller, but if they're driven high / low (as opposed to high-z/low) don't connect it to a C64 - you run the risk of damaging it. (Pins on the joyport are shared with the keyboard matrix, so if the µC drives pins high, there's a risk of bus contention.)
