Hi there,
I just published my first MEGA65 program. It demonstrates a small routine that reads sprites from DATA lines, and also lets the player move a sprite using the joystick in port 1. The joystick movement routine is surprisingly simple, as the JOY()-function's return value can simply be converted into an angle by multiplying with 45, and the angle can be used with the MOVSPR command.
Have fun tinkering around with it!
