I'm currently on 3.3v1 (without October fix) with an old version of HBC and I'd like to upgrade to 4.1 (to have SD menu). As I want to do the less modification possible on my Wii, I'd prefer using official update but since I'll patch IOS60 maybe I should use Waninkoko 4.1 updater. That's why I'd like to know what precisely are the differences between an official update and waninkoko update (except for IOS60 patching) ? I've read in some threads that Waninkoko prevents official patching of some stuff, but I'd like to know what is concerned ? Note: I've asked the question in an other thread, but as it was not the primary subject, I think it's more appropriate to start a new one.
