And second - Wouldnt it be better to port
Bochs emu insted of Dosbox? IMO it's faster and much more compatible (Judging from WINmobile perspective)?
Bochs is actually, or at least historically (they might have optimized it a LOT over the last couple of years, but I doubt it), a LOT slower than Dosbox. Dosbox wants things to run well enough, and particular, wants games to. Bochs' goal was always (again, historically) to emulate accurately. Consequently, a turtle on opium is probably slightly faster than it on anything but a dual core monster desktop machine!
