It basically took me 6 hours of porting over code and resizing assets to make the game work on the Zune HD. Obviously PC/Xbox designed code does not convert that easily to the Zune. But I am happy to say that it was not met with alot of hair pulling (there was some, but that was solved quickly). I am hoping to port my other games to Zune HD compatible code in the months to come before Windows Mobile 7 comes out. If anyone is interested in what I am doing feel free to contact me.
