Pokémon in the Pokémon Ruby and Sapphire, FireRed and LeafGreen, and Emerald Versions are all stored the same way in a 100-byte structure.

Personality value
The personality value controls many things, including gender, Unown's letter, Spinda's dots, any Pokémon's Nature, and others.
OT ID
The Original Trainer's ID Number. Part of the XOR encryption key for the data section, also used in Shiny determination and the lottery.
Nickname
The Pokémon's nickname, limited to 10 characters.
Language
Determines the language of the game the Pokémon comes from. Valid values are:
- 0201 = Japanese
- 0202 = English
- 0203 = French
- 0204 = Italian
- 0205 = German
- 0207 = Spanish
OT name
The name of the original Trainer of the Pokémon.
Mark
The marks seen in the storage Box. These marks serve only to aid in organizing large collections of Pokémon.
| Bit | Mark |
| 0 | Circle |
| 1 | Square |
| 2 | Triangle |
| 3 | Heart |
Checksum
The checksum is of the 48-byte data section in the structure. It is computed by simply adding all the unencrypted values one word at a time. If this value does not match the real checksum, the Pokémon is interpreted as a Bad Egg.
Padding
Any entry marked (Padding) is not used and usually set to either 0 or -1 of the respective data type.
Status ailment
The Pokémon's status ailments are stored as follows:
- 0-2: Sleep bits. Indicates turns of sleep, so 111b = 7 turns, 101b = 5 turns, etc.
- 3: Poison
- 4: Burned
- 5: Frozen
- 6: Paralysis
- 7: Bad poison
Location
A Trainer's team starts at the following addresses in the GBA's RAM (for US games?):
- Ruby: 0x03004360
- Sapphire: 0x03004360
- Emerald: 0x02024190, 0x020244EC for US games
- FireRed: 0x02024284
- LeafGreen: 0x020241e4
Additionally, a wild Pokémon or an opponent's Pokémon will begin at:
- Emerald: 0x02024744
- FireRed: 0x0202402C
There are 6 Pokémon per team, so the whole team continues for 600 bytes afterward.
This structure is used to save data on Pokémon stored in the player's team. The structure for Pokémon saved in the PC stops after the data field, making it only 80 bytes long.
This explains why Pokémon injured by status ailment will cure themselves when put in the PC. It also applies to stats and level, which are recalculated based on Experience.
Thus, there are also 33600 (14*30*80) bytes stored somewhere else in the GBA's RAM to save data on Pokémon in the PC.
When the GBA's saved state (including memory contents) are unzipped into a 740,000+ byte file and viewed, the 14 Boxes of 420 Pokémon are stored in the general region of $038000 $040000.
