It looks like lot of people are having problems with GTR-GTR2-FT Legends... By the way, it has nothing to doo with the wiimote, it's no related. I don't know what to suggest you for those games, I'm sorry.
About FSX and Silent Wings, what are your problems ?

EDIT : try with both version of TirAttack (check
