I hacked my wii back in the day with the zelda exploit. Since then, I have not ran any of Nintendo's official updates. Im still on 3.x. I run my games from a HD using the USB loader GX (pretty typical stuff).
Anyhow, I was wondering, should I get the latest updates for the Wii (4.x)? If so, what are the advantages and would I have to re-hack the machine?
