I am not totally sure how you would get this game to work on a modchiped wii, but that freeze could be due to 2 things........ It could be that your missing the ios needed to play the game but then again if that was the case, you never would have seen the motionplus screen. The other thing (most likely) is that you need to run that game using the same method used for softmodded consoles. That would be placing that dol file you mentioned in the neogamma folder on your sd card, running neogamma with alt dol turned on, watch the motionplus movie, restart the game using neogamma, turn alt dol off and play the game fine. If that is the case, then youl need to softmod the console to get it to work, but once again I am not positive.
