The PadSwitcher64 allows Super Nintendo (SNES) control pads to be plugged into a C64's joystick ports.
The adapter connects to both C64 joystick ports and allows the active port to be changed on the fly with a push of a button. The interface defaults to joy port two on power on.
The DB9 connectors are FEMALE and STRAIGHTHROUGH PCB mounted connectors. You can get them cheap from AliExpress. Same for the SNES degree angled connector. The best place to get the ATMEGA88A micro-controller is from Digikey or Mouser. They are, in fact, BETTER priced there and are 100% guaranteed (no fake stuff!) Also, the interface allows up to four custom mappings to be programmed using a C64-side application. The custom mappings allow any combination of joystick port two and port one control lines to be mapped to any of the Super Nintendo controller action buttons (A,B,X,Y,L,R). Any of the action buttons can also optional rapid-fire function applied, of which a normal and 'inverted' state is available. 'Inverted' rapid fire is simply that when active the output state of t effected button will be opposite to of a normal rapid fire button when pushed. For example, mapping a button to joystick left with rapid fire and another to joystick right with inverted rapid fire will simulate a rapid left/right joystick waggle when both buttons are pushed.
