I have homebrew installed. I need to download ios 249 or watever. I've been told from the readme that I need to put IOS36-64-v1042.wad into the SD root, but such a file does not exist in that download. I only have CIOS36_rev7-Installer.dol, which I have no idea how to use. I have tried putting that into the SD root, but nothing appears in SD channel / homebrew.
