The type chart in the Generation III Pokémon games are stored in a 336-byte data structure.

Format

The data structure consists of 112 3-byte entries, all of which use the following format. Data whose names are marked with an asterisk (*) have more information below the table.

Name Type Description
Attacking Type* byte The type of the move being used.
Defending Type* byte The type of the Pokémon being attacked.
Effectiveness* byte Used to determine the Damage multiplier.

Notes

Types

Types are enumerated like this:

Effectiveness

Hex Dec Description
0x00 0 Totally ineffective, such as Electric on Ground.
0x05 5 Not very effective, such as Water on Grass.
0x14 20 Supereffective, such as Ice on Dragon

Normally effective attacks, such as Bug on Normal, assume a default value of 0x0A (10), so they don't need to be listed in this table.

Foresight and Odor Sleuth

Near the end of the data structure, there are three bytes that signal the end of the normal part of the table - FE FE 00. There are only two entries after this, and they are Fighting and Normal on Ghost, respectively.

However, this area of the table is unique in that all entries in it are ignored after Foresight or Odor Sleuth is used, simply reverting to normal damage.

The end of the table is marked with FF FF 00.
