Comment (by jepael):
Hi, just a few things that might be good to note.
Even the same DOS game executable can use a different PIT divisor
depending on which sound driver is selected. IIRC it will differ whether
you use Monkey Island with Adlib, Speaker, GameBlaster or none. So please
make sure you know which sound device you used to find your divisors. I
may be able to figure out a couple of cases. It will also be trivial to
read back PIT divisor value written to it, or just debug it with DOSBOX to
see which value gets written to it.
And since you have used so many decimals in the calculations, if it
matters, the PIT clock rate is not really 1193182.0 Hz. If you are anyway
using 0.1 Hz units, it is closer to 1193181.8 Hz. The theoretical value is
a fraction that is exactly 105 / 88 in MHz.
