New Super Mario Bros. Wii problem

[Micx]

First, Where is "Unlimited JIT Cache supposed to be? I can't find it in "Config - General"

Second, When I open the game it gives me 2 errors "Unknown cmd *number*" something like that... after I pick how many people will play I just see a moving background and after sometime it gives me an error about the WiiMot I think stopped sync
