Well, actually you need five bits (the 6th bit is changed too)
and therefore "waste" only three. :-)
But if you write AND #%10111111 (and make sure that the carry
is allways cleared before ADC), then you can still use the bits
0,1 and 7 for something else.

Your are right, that doesn't work. I forgot some ASLs which
would make the code longer than yours. My fault.

Here the expression is the address of the first table with the
data of player0, which start at $f308. So #<player0data equals
#$08, and #>player0data would be equal to #$f3.
Have fun!
