For now we will probably stick with the MAME OPL for low end devices 
though. I'm not really sure how much is still to be done on the DOSBox 
code, so starting to change parts of it could make problems later on 
when merging fixes from DOSBox. Of course for the long run we might 
really want to try speeding up the code for lowend devices, for example 
I think currently some sound generation parts are still relying on 
floating point maths (it's only one thing, namely operator generation, 
though AFAIK).
