Title metadata: Difference between revisions

'''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.

'''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 {{Wikipedia|SHA-1}} hashes. The format between Wii and DSi Title metadata ''appears'' to be identical; this includes {{Wikipedia|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.

Example of a Nintendo DSi TMD : http://nus.cdn.t.shop.nintendowifi.net/ccs/download/0003000f484e4c4a/tmd ("HNLJ", or Japanese [[Version Data]].)

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.

The certificate chain at the end of the file seems to always/usually have a size in bytes of 1,792 and a {{Wikipedia|SHA-256}} of <code>03CE2468F00D1AAEA52D7193A2312B0FE87ECE72D43381C3B6BD4C57E700CDD7</code>.
