Laurent, is there really a bug that used a x4 factor instead of x2, or
am I missing sthg inth way dsp emulation runs ? And why 42 cycles are
used instead of 48 ?

Forget it ... One x2 is to simulate a 32 MHz freq (twice the cpu) and the other might be because the dsp can run 2 instructions per cycles ?

But even so, there might be a bug when dsp runs for 42 cycles instead of the expected 48 ?
