To be honest, unless someone give rationale why it should run smoother on incomplete (for N900) OS, I count it as placebo effect. I remember, that you were advocating aDosbox as "faster" few months ago - then, after requests for source code (due to adosbox violating GPL), it turned out to be worth of *none* speedup changes, compared to real dosbox. So, it worked exactly the same way as normal dosbox. If this time You're using regular dosbox on Android, it is also placebo, cause code is exactly same.
