It seems, that the sync signal gets weaker, if the TIA has anything else to do than creating it. Some TVs, like mine, can't syncronize correctly to that and produce a rolling picture. Therefore a save syncronization routine would look like this: LDA #$02 LDX #$00 STA VBLANK STA WSYNC STA VSYNC STA WSYNC STA WSYNC STA WSYNC STX VSYNC Don't do anything between the two accesses to VSYNC, or the signal might get too weak.
