Of course, I have already googled about the subject, and I have already read through the many posts about Dosbox on the Maemo site. But I still did not find the answer to my question.

I hope that someone with experience using Dosbox on the N900 might answer, especially about the main point --- using the keyboard mapper provided, I think, by Javispedro, do all the keys work now? Or can they be made to work for any particular application, by rewriting the mapper?
