DB9 joystick does not want to work. #12

Closed prcoder-1 closed 6 months ago

prcoder-1 commented 6 months ago

The DB9 joystick does not work. At least for me... Only HID joystick works. But it is not very playable due to the limitation on one key at a time. This happened after adding an HID joystick. I think this is because the port became inout instead of input.

I think it is my hardware problem. Sorry for the inconvenience.
