I am working on a harmattan port (although I don't have an N9). These are the build errors from Qt Creator - http://pastebin.com/PeP34MSa . There should be an Arm Jit in the next version (0.6) however I don't think it will be smooth on Fremantle (n900) or most of the android phones (except for the very simple games)

EDIT: Ok, I am now here - https://github.com/hrydgard/ppsspp/issues/347
