Ok, i got most of this already, such as _getky saves a number to OP2 and
stuff, but then i can't make it if then else... I tried compiling the
following, but tells me the OP2's are unused data. The compiler tells me it
can't recognize OP2, but it recognizes _OP2, but its unused. I also tried ld
b,OP2 and ld b,_OP2, but it doesn't work for me. Help!

SpriteMove:
 call _getky
 ld a,24
 cp _OP2
 call z,Left
 ld a,25
 cp _OP2
 call z,Up
 ld a,26
 cp _OP2
 call z,Right
 ld a,34
 cp _OP2
 call z,Down
 push bc
 ret

This must be yet another of my stupid mistakes...
