another joystick test, bitwise, looped, with comments too (c64)
; minimal joystick test #3, 21 bytes loop version; @ = not set, A = set
* = $1000
INIT LDY #8 ; init loop for checking all joystick port bits
LDA $DC00 ; load joystick port byte
LOOP PHA ; make a copy and put it on the stack
AND #1 ; least significant bit set?
