General Save File Structure

A Pokémon Diamond and Pearl save file is divided into two pairs of blocks. Each pair consists of one general block, one storage box block, and one hall of fame block. The storage box block contains current information regarding Bebe's storage system, including stored Pokémon, box names, box wallpapers, and the current open box. The general block contains current information on every other aspect of the game's progress, such as the trainer's name, ID number, acquired badges, party Pokémon, items, and much more. The hall of fame block contains information about the Pokémon used to defeat the Elite 4. The other pair is a backup from the previous save.

The first general block in the file begins at 0x00000. The first storage block begins at 0x0C100. The first hall of fame block starts at 0x20000. The second general, storage, and hall of fame blocks are at the same address + 0x40000. The current blocks are not always stored in linear order in the save file (i.e. if the second general block is the more current, the first or second storage box block can possibly be the current as well).

Block Footers

The last 20 bytes of each general and storage box block is a footer. The last 24 bytes of each hall of fame block is a footer. The footer is used to determine:

  • The size of the block
  • Whether the block is current or a backup.
  • Which big & small blocks link together.

General/Storage Box Footer

Offset Purpose
0x00 - 0x03 Storage Block Save Count
0x04 - 0x07 General Block Save Count
0x08 - 0x0B Size of block
0x0C - 0x0F Run-time usage
0x10 - 0x11 Run-time usage
0x12 - 0x13 Checksum

Hall of Fame Footer

Offset Purpose
0x00 - 0x03 Save ID number
0x04 - 0x07 Save index number
0x08 - 0x0B Run-time usage
0x0C - 0x0F Run-time usage
0x10 - 0x13 Size of block
0x14 - 0x15 Run-time usage
0x16 - 0x17 Checksum

Loading/Saving A Save File

When one starts a new game for the very first time, every byte of the save file is set to 0xFF. The first time the game is saved, the "current" info is written to the second half of the save file. This is important to note when loading a save.

When the game loads a save file, it first compares the small block save count of both general blocks. If the general block with the highest save count has a correct checksum, then the game moves on to check the storage blocks. The storage block with the highest storage block save count is chosen first, and if its general block save count matches the currently chosen general block (and has a correct checksum), the file is successfully loaded. If both storage blocks have the same storage block save count, then the storage block with a higher general block save count is chosen instead, and the if the checksum is correct, the file is successfully loaded. If the checksum was incorrect for either block, the game falls on the other pair of general and storage blocks; if the checksums are correct in both, the game reports a save file corruption error, and that is the data loaded. If the checksum in either block is incorrect, the game reports a save file corruption error, and the save file is not loaded. A new game must be started at that point.

When the game saves data, the general block save count is incremented + 1. If nothing in the storage block has changed, then no changes are made to the storage block and no further changes are made to the general block. However, if changes have been made to the storage block, then the storage block save count is incremented by 1 in both the storage block and general block footers. At this point, the backup general block is overwritten with the new general block data, and (if changes were made to the storage block), the backup storage block is also overwritten. This is the reason why the game varies on how long it takes to save.

Thus, either general block can be linked with either storage block, and the current pair is identified using the footer information.
