Related question: where can I learn about the various incantations of "armboot.bin", "ppcboot.elf", "boot.dol", "boot.elf", etc.? The reason I ask is because I have a ton of copies of those files from various ZIP files, and there are basically two sizes of "armboot.bin" (49K and 167K), and three sizes of ppcboot.elf (189K, 191K, and 309K). It seems that only the 49K armboot.bin works for me, and the 191K and 309K ppcboot.elf files work. But almost all the ZIP packs have the 167k/189k pairing, and those never work for me. By "not work" I mean powering on the Wii results in black screen and nothing else. By "works for me" I mean the BootMii page loads.
The other reason I ask is because I can't seem to load anything useful (e.g. MMM) via BootMii. I saw reference to bootmini -- I wondered if the tiny armboot.elf is actually a crippled mini form that doesn't allow MMM to load? Thanks for any pointers -- I Googled for way too long already today! :-)
