They must have messed up the cycle count then. I really don't believe that processing during VSYNC could mess up the pulse, since it is essentially a digital signal. But we all know what happens if you wait 78 cycles before STA WSYNC, or if you think you've waited 76 to get 2 lines when you only have 74. Of course someone with an oscilloscope, a VCS, and a cart could probably clear this right up. --Roger Williams ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
