- fire_r_same/up are now 10/12 instead of 8/15 cycles
some jmps can probably be replaced with appropriate branches instead

pt3: add support for scaling the frequencies from 1.77MHz to 1MHz
...
The ZX Spectrum (default for pt3 files) runs the AY-3-8910 at 1.77MHz.
We do this by multiplying by 9/16 (which is a pain, but could be worse)
