IIRC, int21h is based upon DOS3CALL except for some few parts which are
only implemented in int 21h.

I mentionned this in the post and I also think it's the best solution since
only pure dos apps may need a lot of base memory.

Could you be more precise?
What the problem(s) that may make things not work?
Or what do the apps do we cannot handle?

Hum... Since the code already exists in WINE, I prefer understand it and
enhanced it. I think, It will take much less time. ;-)
