I have my Sisters Wii, It's modded, but I can't remember what mod it has at the moment. I think it's one of the first original ones. (I did it with The legend of Zelda a while back). It can play A Backup Copy of Mario Kart Wii, But I lent her my Legit copy of Epic MIckey and she can't play it. (It can also play Brawl) So I want to update it and mod it(I don't know what version it is but it can't play things off the SDCARD) So My question is what do I need to do and how do I update it?
