Right -- I was able to do that and that's how I measured the huge
improvement in performance on the PSP. Normally the OPL2 processing
takes around 40% of the total processing time. This drops to 20% or
less with the Dosbox OPL. However, I won't make it the default so long
as the music is inaudible in Scumm.
