Pmd2 item s p.bin

The "/BALANCE/item_s_p.bin" file in the Pokemon Mystery Dungeon: Explorers of Sky game is used to store data for the "exclusive items". Its wrapped in a SIR0 container.

File Structure

Overview

Offset	Length	Name	Description
0x00	16	SIR0 Header	A SIR0 header wrapping the item data.
0x10	(NbEntries * 4)	Item Data	A block containing entries for all exclusive items.
After Item Data	3	SIR0 Pointer Offset List	A list of encoded offsets to the pointers in the file. Since there are only the 2 pointers of the SIR0 header, those three bytes are always 0x04, 0x04, 0x00.
After SIR0 Pointer Offset List	13	Padding Bytes	Since all entries have a fixed size, and the SIR0 Pointer Offset List is 3 bytes long, 13 0xAA bytes are used as padding to align the end of the file on 16 bytes.

Offset	Length	Type	Name	Description

0x2	2	uint16	Item Parameter	A parameter that depends on the item type.

Item Type

A list of the possible type values an "exclusive item" can have. This list is based on data compiled by nhahtdh into the item_p_sky.xlsx excel document, and then verified/confirmed on our end.(See links in the Credits section. )

The type can determine these things:

• The star rating of the item. (rarity)
• Whether its Pokemon-specific, or type-specific.
• If its a 1 star item, which of the 2 possible 1-star items is it.
• Whether its an item that a Pokemon can randomly get when hatching.
• And possibly, an additional unknown trait.

Here are the possible item type values, and what they imply:

Value	Rarity	Item "Slot"	Exclusive To	Extra Trait
0x0	-	-	-	-
0x1	*	1	A Type	-
0x2	*	2	A Type	-
0x3	**	-	A Type	-
0x4	***	-	A Type	-
0x5	*	1	A Pokemon	-
0x6	*	2	A Pokemon	-
0x7	**	-	A Pokemon	-
0x8	***	-	A Pokemon	-
0x9	***	-	A Pokemon	The Pokemon may hatch holding the item.
0xA	***	-	A Pokemon	? (Only all the Eeveelutions, and the Tyrogue line have items with this type! )

Item Parameter

The parameter's value changes meaning depending on the exclusive item type.

Here are the two cases:

• If the item's type is set to "exclusive to a Pokemon", the parameter contains that Pokemon's National Pokedex number.
• If the item's type is set to "exclusive to a type", the parameter contains the ID of the type. (See monster.md's page for a list of values for each types.)
