Re: A85: FIND_PIXEL



I don't think that is correct.  I know in PutSprite, it has some lines
of code to the effect of:
ld a,63
sub c
ld c,a
This is to reverse the origin from the bottom left to the top left.  I
think the top left corner is most commonly used as the origin since
this is the way it is done on the PC (i think).
