Pokémon DP Save File Structure

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	Save ID number
0x04 - 0x07	Save index number
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 the game loads the save file, it first compares the save index number of each small block. If the small block with the highest save index number has a correct checksum, then the game checks to see which big block has a matching ID number. If both big blocks have the same ID number as the small block, then the big block with the highest save index number is chosen. If the big block chosen by the save file has a correct checksum, then the game loads successfully. If the checksum is incorrect in either the small or big block, the game reverts to the other block pair. If either of their checksums are incorrect, then no data is loaded, and a new game must be started.

When the game saves data, the save index number is incremented + 1 from the current save index number, and the backup small block is overwritten with the new data.

If nothing in the big block has changed, then the save ID number in both blocks is retained. However, if changes have been made to the big block, then the backup big block is overwritten with the new data, and a new save ID number is generated, which is then written to the new small block. This is the reason why the game varies on how long it takes to save.

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