I've verified this on a few games and it looks like the 'audiofix' code will cause any GameCube game to crash when the streaming audio is going to play. All the Naruto games have the streaming audio so I believe that is why they all crash as well. Maybe the Wii JAP games that are crashing are using streaming audio calls as well and this is why they are crashing? Just some theories based on other posts I've seen. Can anyone confirm GC streaming audio games FULLY WORKING on their WiiKey?
