Another think I suggest are a customizable overlay keys. We should consider that there are already a few games that fully rely on the keyboard and not all Maemo/Meego devices will have one. I suggest a customizable keyboard that can show button on the screen on top of a running application.

Also I "found" my "original" cd and the game installs without DOSBox.
Also in case you have an image of your original CD you can just copy the content and install it from there, no need to mount or anything.

Just make sure to copy the XLDLIBS folder from the CD/image into your installation folder and empty the SETUP.INI file.
