'''Title metadata''', or '''TMD''' for short, is a format used to store information about a title (DSiWare, etc.) and all its installed contents, including which contents they consist of and their SHA1 hashes. The format between Wii and DSi Title metadata ''appears'' to be identical; this includes endianness, so byteswaps are often needed on the DSi.

Many operations are done in terms of 64-byte blocks, which means you will often see padding out to the nearest 64-byte boundary at the end of a field.

The certificate chain at the end of the file seems to always/usually have a size in bytes of 1792 and a SHA256 of 03CE2468F00D1AAEA52D7193A2312B0FE87ECE72D43381C3B6BD4C57E700CDD7.
