I will try!

im sorry but you cant

you can whith mods/cheats in to the inventory but it dosnt work

I don't if will work because maybe there no texture for the command block

there is a texture for it

I've seen it happen in game before the servers went down, so you could probably use it.

So its is possible? I take a world with command block then via file transfer i send to the wiiu to the correct data folder of minecraft, and will work?
