Installing the wrong region system menu WAD would brick a Wii (region changing is a whole process that requires more than just a system menu WAD) but that's about it. Channels are perfectly safe. On vWii specifically, the things to avoid are system titles like system IOS and system menu because they're different than on Wii.How so? I heard that the original Wii had problems with that at least. The WAD from the wrong region would certainly brick it.
Some people tried to region change but didn't do it correctly and ended up with a brick, and some people tried to manually update their Wii by installing the latest system menu WAD, but forgot to install the corresponding IOS that goes with it and is required for SM to work. And a lot of people installed cIOSCORP/DARKCORP, which normally doesn't cause bricks, but if something went wrong during installation it's possible. All of these things would be a very bad idea on vWii since system menu WADs don't work on vWii unless they're encrypted with a special key and cIOSCORP/DARKCORP would brick it guaranteed.Why would people install system menu and IOS WADs?
That goes only for Wii Shop Channel WADs then, right? I take it Wii U eShop titles can be launched regardless of the region.
So how good is launching them from USB Loader GX compared to just installing it to the vWii's NAND? Are saves easy to access, as in, visible from the Wii Menu like any other standard title? Because if so, I may as well just copy and launch every WAD from there. Do you know of any updated tutorial on how to do that?
