Nice...
LDA #212
STA xdelay
LDA xpos
CLC
ADC #02
SEC
DivideBy3
DEC xdelay
SBC #$03
BCS DivideBy3
This version is MUCH slower and can eat up a whole extra scanline depending
on the value of xpos. Very handy if you need to burn up those pesky,
unwanted free cycles. If it weren't for the Atari's oceans of RAM and
blazing fast CPU, we wouldn't have to hack together workarounds like this.
Thankfully, today we can rely on Windows to quickly and efficiently consume
every free resource without writing a single line of assembly.
