What you need:
A VC game purchased on your Wii
A VC game purchased from another Wii
A SD Card
A Hex editing program (I used XVI32)
This idea may seem simple, but the encryption Nintendo put on their Virtual Console games is complex.
Using XVI32, I opened “a shared” content.bin of the game “Super Mario 64.” And looked into it. Scrolling all the way down I came across this number
I think If you can replace this number with the number on your content.bin of ANY game, it will work.
