Booto: /* Content info records */

'''Title metadata''' is a format used to store information about a title (a single standalone game, channel, etc.) and all its installed contents, including which contents they consist of and their SHA1 hashes.

[http://git.daifukkat.su/?p=3dshax.git Code is available] by trap15 to parse the available information from the 3DS format of TMDs.
