Each item has a number used to identify it in any game. The following list enumerates them according to the way they are stored in any Generation I Game Boy game.

The names of items are stored in the ROM of Red and Blue at offset 0x472B with one byte for every character. An additional byte (with value 0x50) is used to tell the game that the next item belongs to the next index number.

Invalid items (adjacent names)

The names of items end at offset 0x4A62. Following on directly from offset 0x4A63 are a list of floor names which are stored in the same format as items, meaning that they can be forced to appear as items, although they do not have valid effects and can freeze the game when used. These names are used by lifts and are retrieved from the same ROM location, meaning there is nothing in the game to suggest that these would once become real items.

# Hex Item
084 0x54 B2F
085 0x55 B1F
086 0x56 1F
087 0x57 2F
088 0x58 3F
089 0x59 4F
090 0x5A 5F
091 0x5B 6F
092 0x5C 7F
093 0x5D 8F
094 0x5E 9F
095 0x5F 10F
096 0x60 11F
097 0x61 B4F

Proceeding the list of floor names (0x4A92) are a series of unused names written in Japanese, ending at (0x4B08).[1] Although these names do exist in the English Red and Blue, the names are illegible because the character table for the localised Generation I games is incompatible with Red and Green. The names may have once been part of multiple lists. Like the list of floor names, they do not have valid effects when forced as items.

# Hex Item
098 0x62 かみなりバッヂ*
099 0x63 かいがらバッヂ*
100 0x64 おじぞうバッヂ*
101 0x65 はやぶさバッヂ*
102 0x66 ひんやりバッヂ*
103 0x67 なかよしバッヂ*
104 0x68 バラバッヂ*
105 0x69 ひのたまバッヂ*
106 0x6A ゴールドバッヂ*
107 0x6B たまご*
108 0x6C ひよこ*
109 0x6D ブロンズ*
109 0x6E シルバー*
109 0x6F ゴールド*
109 0x70 プチキャプテン*
109 0x6D キャプテン*
110 0x6E プチマスター*
111 0x6D マスター*

Other names appear onwards from (0x4A92) before the names of HMs and TMs, appearing as glitch items. Whereas some glitch items have invalid names, others appear with names such as the name of the player's rival.[2]
