// Common labels used in this file: // magicnum - control ints or shorts found in all tmds // zeros - bytes all filled with zeros // undef - non-zero data of unknown purpose // sign - zero-terminated string padded to 64 bytes // probably used in the signing process // hash - probably 20, 512 or 1024 byte hashes // // # in fornt of a comment signifies entires that are // the same in each tmd-files the author checked // // ! Remember the Wii has a LITTLE-ENDIAN processor. When ! // ! working with ints or shorts on none-LE machines  ! // ! (Intel PC and Mac) you need to swap the byteorder.  !
