Euhm.. how can I say that? That's now how it works.. Sorry
You can't get a blank CD first of all.. and if your project is actually to use Nintendo's propriety (being Mario), they will never give you a blank CD.
Secondly, injecting Roms into the WiiU is not even done yet! I'm not even sure if someone already ripped the SM64 WiiU Channel.
Next, how are you gonna work with this? I never saw a multi-screen console before beside the DS and now you're talking about 8 screens? That's a little too much.
This is not a hate comment btw, I even like the idea.
But I think that's not really possible to do without a lot of work.
Thanks for understanding.
