However, the sprite defintion seems wrong to me
1 - the form should be
data 1,0,0,0
2 - , line 7920 should be:
7920 POKE_L BlankPtrAdd+20,0:REMark Pointer to next definition
(there is none)
3 - Im' not sure whether the size should be 0
try ti set it to 0,2,0,2
Here is a null sprite definition (in asm) I *Know* works:
sp4_vide ; this is just an empty sprite
DC.W $0100,$0000
DC.W 2,2,0,0
DC.L sc4_vide-*
DC.L sc4_vide-*
DC.L 0
sc4_vide
DC.L $0000,$0000 ; just a transparent sprite
I hope this helps
Wolfgang
