Does this make >sense to you? Not a bit! ;-) I have tried your experiment and can confirm your results, except that I get only two copies at Hit5. This might be the same incompatibility as with the trick18 program. What version of the VCS are you using? Can all of you please try out the enclosed 2or3.bin on a real VCS and tell us if you see 2 or 3 sprites and which VCS modell you are using? I also did the same experiment with a NUSIZ value of 6 (3 copies medium) and got 3 copies for the second hit at cycle 11 and 22. So in both experiments I got 3 copies when I hit RESPx 4 or 3 pixels before the next sprite of the first set would be displayed. One cycle later, which is 1 or 0 pixel before the next sprite of the first set, I got only 2 copies. Maybe I need to revise my 5 pixel delay theory again. ;-) Ciao, Eckhard Stolberg
