Because Nintendont enters GC mode and Nintendont is not a full Wii emulator, I can be sure of that.If Wii games have a Home Menu why can't Nintendont?
Granted, it "emulates" some things like controller input and other stuff, but the game loader itself is an interpreter, not an emulator.
When it enters GC mode, you lose some of the permissions the Wii has, like the Home Menu and its options.
I might just be throwing random shit at the air, but @FIX94 might give a better explanation to this instead of noobish words like mine.
