Notes
Personality value
The personality value controls many things, including gender, unown letter, Spinda's dots, 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.
Font
Determines which character set is used for the nickname (?). This is used to determine what colour should be used to write nicknames in a Pokemon status. They may appear in either blue (boy) or pink (girl).
OT name
The name of the original trainer of the Pokémon.
Mark
The marks you see in the storage box. bit 0: Circle bit 1: Square bit 2: Triangle bit 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
- FireRed: 0x02024284
- LeafGreen: 0x020241e4
Since there are 6 Pokémon per team, so the whole team continues for 600 bytes afterward.
