Re: A85: Another newbie question, about sprites
Does this work?:
ld bc, $2020
ld hl, (&A_shape) ; Should parens be around something here?
ld a,4
out (5),a
#fncall PSPR_NR
ld a,0
out (5),a
A_shape:
.db 8,8
.db %00000000
.db %11111110
.db %10000010
.db %10000010
.db %10000010
.db %10000010
.db %10000010
.db %11111110
