So i founded some kind of bug form disc channel. Wii propably save's something to its memory from disc aka bootloader or something. And when its starting game it checks the disc and reboots if its not right. So if we have example zeldas boot thing on dvd it could run? But im pretty sure that this isnt anything remarkable or usefull. VIDEO if anyone wants to try here's how to: 1) put wii to stand by mod 2)change disc 3)remove power cable right after that 4)power cable back and power up wii 5)if your first game was wii sport and you changed it to zelda disc channel now shows you that you have zelda inside.
