FO 09:44 PM Bug #67: Pokey two tone timing problem

I found if I pokey 53775,11+128 on the Atari then it matches the Eclaire output. Unfortunately forcing the serious output on eclaire to 1 or 0 does not change anything. Still its something to go on! foft

So, errr identical then! Going to have to think about this one...
B is Atari, A is EclaireXL.

Nope, seems to be some interaction with the noise filtering. I wonder if the delay also needs applying to the pulse from the timer, that then hits the noise filter. foft

A 2 cycle delay on the reset fixes both the 4 cycle and the 9 cycle case.
Now to check this specific example! foft
