Nintendo Wii Title-Metadata (tmd) file structure
A "title" is a standalone entity -- a game, a channel, etc. Titles can be made up of multiple "contents". (Don't ask me I just work here.)
// 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 front of a comment signifies entires that are // the same in each tmd-files the author checked typedef unsigned char u8; typedef unsigned short u16; typedef unsigned int u32; typedef unsigned long u64;
