This works as fine as my updated version of
Roger's patch (see my previous mail), and
IMHO should be included to next release, it's
such a significantly improvement for EmuTOS.

I don't think there's any significantly
CPU usage difference.


What about old AUE core, will you do similar
change there, or will we just decide it's too
inaccurate for DSP music playback anyway?

(And going to be removed in few releases.)
