Compared with running raw DosBox:

We can see that Wine tries to do many crazy things, like mounting plenty or
drives or running in secure mode.

Also the code handling DosBox would benefit from being more modular, from
having the functions as short as possible.

Plus most of the auto-configuration is better implemented in DosBox itself.
