As I don'thave easyptr, I can't really comment. 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 ----------------- www.wlenerz.com
