Elk Attack, on the other hand, does nothing. > Maze003, on the third hand or foot or something, works like a charm... Elk Attack is 8kb and should not work on the SC anyway, but the rest of your problem sounds like the problem I had with my TV and that has filled several threads on this list already. :-) The problem is that your vertical hold is off a little bit. The TV broadcast and most VCS games will work, but some games with time saving syncing routines won't. If you do: ldx #0 lda #2 sta WSYNC sta VSYNC sta WSYNC sta WSYNC sta WSYNC stx VSYNC everything should work fine even on a slightly detuned TV. But if you do something between the three WSYNCs, like setting up a timer, the picture will roll. I have no idea why this happens, but it should be possible to tune the vertical hold so that all VCS games and the TV broadcast will sync fine.
