ok i'm trying to make my wii able to play back up games. my wii is verison 3.3U i installed the hbc a while ago to be able to play brawl+ and it worked. but i tried to install dvdx and it did not work and i researched why, and i think my wii may be something called 3.3 v2 or something like that but i tried the 3.4 version and it said it worked. the hbc updated and i installed dvdx through that too and it worked and also installed the bootmii boot 2. everything seems to be working right at the moment but i haven't backed the nand yet because my sd card isn't big enough so i'm gonna buy a new one soon. so now i'm wondering what i should do next because i don't want to screw up what i have done so far or brick my wii and since i have bootmii boot 2, should i install preloader(what is it, whats different)?
