Because the HackMii guys and many other people say that CIOSCorp is too risky, I've refrained to use it for a while. But I recently got Rock Band 2 and for some reason the DLC stacks up in my nand even if SD mode is enabled. I read that by loading Rock Band through the Disc Channel, this isn't a problem... but my Wii has a tendency to damage discs (I had to buy Zelda TP two times because a part of the game before the Mirror Chamber was damaged), so even for the games I legally own I use backups. For this reason, I have to install CIOSCorp to play RB2 through the disc channel. So my question is, is cIOSCorp really as dangerous as people say? Also, I read that cIOSCorp was not compatible with the HackMii installer. But if I already had BootMii before, I can still do NAND backups and restores, right?
