16 Price 2 bytes
18 Hold effect 1 byte
19 Parameter 1 byte
20 Description pointer 4 bytes
24 Mystery value 2 bytes

27 Type 1 byte

Pocket

This determines which pocket of the Bag the item should be stored in. This does not prevent the item from being in another pocket, though. The game uses it to see where it should place the item upon collection.

For FireRed and LeafGreen

Number Pocket
1 Items pocket
2 Key items pocket
3 Poké Balls pocket
4 Berries pocket
5 TMs and HMs


For Emerald, Ruby and Sapphire

Number Pocket
1 Items pocket
2 Poké Balls pocket
3 TMs and HMs
4 Berries pocket
5 Key items pocket

Type

For items other than Poké Balls, the type determines how the item can be used. With Poké Balls, the type indicates the Poké Ball type, and is one less than the index number.

Type Description
0 Mail
1 Items which can be used out-of-battle.
2 Items which must be used in a certain location; key items of this type can be assigned to select.
3 Only the Pokéblock case is of this type.
4 Items which cannot be used out-of-battle.

Parameter

A parameter used by different kind of items. It is used to represent the number of steps repels and flute effects last. HP and PP recovering items have this value as their number of HP/PP recovered, but the actual number of HP/PP restored is stored in a different table.

Mystery values

Mystery value 1 is:

  • 0 for normal items.
  • 1 for HMs and most key items.
  • 2 for some plot-related key items: Blue Orb, Devon Goods, Letter, Oak's Parcel and Red Orb.

Mystery value 2 is:

  • 0 for most items.
  • 1 for many key items: Acro Bike, AuroraTicket, Berry Pouch, Bicycle, Fame Checker, Good Rod, Itemfinder, Mach Bike, Magma Emblem, MysticTicket, Old Rod, Old Sea Map, Pokéblock Case, Powder Jar, Rainbow Pass, Ruby, Sapphire, Super Rod, TM Case, Tea, Teachy TV, Town Map, Tri-Pass and VS Seeker.

Battle usage

Battle usage can be:

  • 0 if the item can't be used in battle at all.
  • 1 if the item's effect is seen during battle but on a subscreen, such as healing items.
  • 2 if the item's effect is seen in battle such as Poké Balls.

Extra parameter

Extra parameter is used to distinguish Poké Balls and Mails, as opposed to just using the item index.

Offsets

These are for US Versions:

  • Ruby: 0x083C5564
  • Sapphire: 0x083C55BC
  • Emerald: 0x085839A0
  • FireRed: 0x083DB028
  • LeafGreen: 0x083DAE64
