Well, this is what you wrote that you saw when you ran unstable.bin. I
decided to take another look at it and today, including the unstable
sprite at position 9 (counting from 0) I see a total of 18 sprites.
This means that there is one other sprite that you're not seeing. So I
decided to put my cycle counting skills to the ultimate test and see
what's happening. Of course I'm not sure of anything :-) I often
confuse zero with one!
So unstable does RESPx and should produce nominal sprite positions
according to the following table:
Cycle Sprite1 Sprite2 Sprite3
resp0 21 0 16 32
resp1 24 9 25 41
resp0 27 18 34 50
resp1 30 27 43 59
resp0 39 54 70 86
resp1 42 63 79 95
resp0 51 90 106 122
resp1 54 99 115 131
resp0 64 129 145 161
resp1 67 138 154 170
I see sprites at the following positions, including the unstable Player
1 sprite at position 9. The Player 0 sprite predicted at position 161
shows up at position 1.
Player0 at 1, 18, 34, 50, 70, 86, 106, 122, 145
Player1 at 9, 27, 43, 59, 79, 95, 115, 131, 154
I was wondering where you (or anyone) saw sprites, and if you had a
chance to try the program on any of your other machines?
