I have a Wasabi DX mod chip. I just updated my wasabi to 3.0, and now my NSMBW works (YES!!!), but only for like 15 minutes (NOOOOO!!!). How do I make it work longer? And i have a 4.0U wii. Do i need to upgrade higher? I just dont want my wii to brick. Would taking out the WASABI DX modchip, updating, then putting it back in work? I also want super mario galaxy 2 so tell me about that too. And can i play online? Please try to answer at least one of these questions. Thanks for those who were helpful!
