A person named Blue has stated that he would attempt to use an external HDD to store RB2 DLC, from this thread From what I've read so far, one way to get this working is to load Rock Band 2 (a legit disc) through a NAND Emulator, so the 512 MB limit is eliminated. I haven't tried anything yet, as I wanted to know if it was possible before trying anything. My external HDD is a Seagate FreeAgent 500GB HDD, and I have a 32GB partition made in FAT32. (I'm not even sure if NAND Emulators work off of an HDD). So far, I don't believe it will work, as HBC does not recognize my FAT32 partition with the "apps" folder on it. My other partition is NTFS, and does not have an "apps" folder on it. Secondly, I backed up my NAND with BootMii. Some of the squares were black, which means they were bad blocks. What does this mean exactly, and how does it affect my Wii console? Will I still be able to use the NAND Emulator? What about Dolphin: Wii Emulator? In-depth answers would be appreciated. Before I take any steps, I want to know what each step does and why I'm doing it. Thank you.
