Also, Ive just downloaded Showmiiwads..
Loaded one of the wads to try it.. now ive noticed that there is an option to "Create Common Key"
Do I just select that option, copy the "new" common-key.bin from the Showmiiwads folder
Replace the "common-key.bin" in the WADS2NAND folder?
Then presume to reinstall the wad from there again?
