Here is the quickest test I could come up with. This uses the players from Red vs. Blue.

lxa_test_1.bin uses...

lda animationFrame
and #$07
tax
lda LowPlayerTable,x

and lxa_test_2.bin uses the illegal op...

lda animationFrame
lxa #$07
lda LowPlayerTable,x

What you should see is the player in a running animation. When I run the illegal op version in Z26 I just see the player in animation frames
6 and 7.

Anyone able to try this out on their VCS? I can try it on my 7800 and 2 switch via the CC later this week.

Take care,
Dennis
