/title/00000001/00000002/data/tmds.sys seems to store TMDs for deleted titles. Each entry has the following syntax: (in C-structs, because they're easy to handle)

 typedef struct {
      u64 titleId;
      u32 unknown; // Unknown, seen values: 0x0208 (index?)
      u8 padding[18];
      struct TMD tmd; // excluding cert chain
      u8 padding[24];
 } tmdsSysEntry;

This file is interesting because it contains factory TMDs.
