hi all, i done some digging myself and found out that to make SSBB (PAL version not sure about US) work through the disc channel you need to update your wii using the update available on the SSBB disc.
two things i am not sure about,
first, is the update on SSBB safe? i have read that it does not effect HBC and twilight hack but does it stop and remove WAD installations and wii trucha signed discs?
secondly would installing the SSBB update make Mario kart work?
off topic, is there an latest shop channel update available? its just that ever since the 3.4~4.0 update been going around i have not updated my wii system (still on 3.2) and i kinda miss the Nintendo channel and shopping on the shop channel for wiiware etc.
the new update also has support for 32GB SDHC and the running Wiiware VC of off the SDHC, it would be cool if this new update was hacked
will just have to wait.

but do let me know if there is a shop update and system update avlable that keeps the old stuff plus adds the safe/good part of the new update.
