I have bootmii .2 installed on my boot2. My question is can nintendo release a firmware that will somehow make backing up or restoring the NAND different, therefore needing a new version of bootmii? For example lets say I want to upgrade(sometime in the future) to firmware 5.0U, but one of the conflicts is that bootmii can longer be used as it should normally. Is this possible? I guess the big question is, can bootmii work no matter what nintendo does to the firmware? Thanks.
