Keep the updates going...
Follow MauiFrog's guide down to the teeth! His guide get your will on tip-top shape...I also recommend staying on system version 4.3 (as recommend in the guide)
I strongly recommend reading up on what D2X is and why it's so AWESOME!
MauiFrog's guide makes sure that you have D2X version 7 installed...later you can update to version 8 and get practice for subsequent updates, this way your wii can be updated in a snap without the need to start from scratch...!! :027: Other site's guides do not compare to the amount of knowledge available in this site.
