I'm playing around with writing my first 6309 program.
I'm not in a hurry; I'm relearning things along the way at a slow pace.
Added conditional assembly for 6809 vs. 6309
Added joystick routine adapted from a code example by Richard Goedeken.
Now moving the joystick moves green lines around.
Okay, now all the dots bounce around randomly.
The joystick button now plays a laser sound.
Fixed joystick fire button debounce with advice from Steve Bjork.
Now there's an explosion when you hit the fire button.
Added spider and fireball animations.
Targeting reticule instead of green lines.
Added new sprite code that's slower but has collision detection
