I installed bootmii as boot2 and I maked a NAND back-up in case if somethings happens. But that NAND back-up was made a year ago. Between that time, I installed a lot things on my wii. So my questions was, should I need to make a new NAND back-up and yes, can I do that on same way how everyone make a NAND back-up? Or should I delete my back-up first? I hope you can help me. PS: sorry for mai bad "Engrish"
