Glitch item

Glitch items are invalid items in the Pokémon games. Unavailable items such as Pokémon FireRed and LeafGreen key items in é may also be considered to be glitch items, as well as unused/unavailable items such as ????? (hex:07) and BoulderBadge (hex:15) — see unused items.

Glitch items may have special uses (in Generations I and II), different names (in Generation I and to an extent Generation II) and Poké Mart buy and sell price data.

Some glitch items such as "9F" (hex:5E) in Pokémon Red and Blue or Pokémon Yellow, or "RIVAL'S" (hex: A2) in Red and Blue, or "o" (hex:94) in Yellow always have the same use(s).

Other glitch items execute data in writable memory, with a select few glitch items such as such as "8F" in Pokémon Red and Blue (hex:5D) and "ws m" in Pokémon Yellow (hex:63) being ideal for arbitrary code execution.

In Pokémon Red, Green, Blue, and Yellow

Glitch items occupy index numbers hex:00, hex:54 through to hex:C3 and hex:FB through to hex:FF.

Many glitch items are available with the Celadon looping map trick, Item creation glitch (a Select glitch in Red/Green/Blue), Yami Shop glitch and other Poké Mart vendor glitches.

Examples of particularly useful glitch items include:

In Pokémon Gold, Silver and Crystal

Glitch items in Pokémon Gold, Silver and Crystal occupy a number of index numbers, as such:

Hex ID Dec ID Item 00 0 ? 06, 19, 2D, 32, 38, 46 (G/S only), 5A, 64, 73 (G/S only), 74 (G/S only), 78, 81 (G/S only), 87, 88, 89, 8D, 8E, 91, 93, 94, 95, 99, 9A, 9B, A2, AB, B0, B3, BE 5, 19, 45, 32, 38, 46 (G/S only), 90, 100, 115 (G/S only), 116 (G/S only), 120 (G/S only), 129 (G/S only), 135, 136, 137, 141, 142, 145, 147, 148, 149, 153, 154, 155, 162, 171, 176, 179, 190 Teru-Sama C3 195 TM04 (useless) DC 220 TM28 (useless) FA 250 HM08 (disambiguation) FB 251 HM09 (disambiguation) FC 252 HM10 (disambiguation) FD 253 HM11 (disambiguation) FE 254 HM12 (disambiguation) FF 255 HM13/CANCEL/Berry

Note that Teru-Sama items which are not Teru-Sama in Crystal are the key items "Clear Bell" (hex:46), "GS Ball" (hex:73), "Blue Card" (hex:74) and "Egg Ticket" (hex:81) respectively.

TM and HMs outside of the correct pocket

Additionally, all of the normal TMs and HMs will serve as glitch items when used outside of the TM/HM pack, due to having invalid execution pointers.

Below are a number of useful TMs and HMs to use outside of the relevant pocket.

(Sources: [1], [2], [3])

Hex ID Dec ID Item Version Use CE 206 TM15 Crystal (Japanese) Executes arbitrary code from FA10 (Echo RAM for DA10, which is somewhere in the expanded Balls pocket. If "(item) x195", "Star Piece x 252" (represents C3 84 FB - a jump to FB84, box 4 name character 2) are stored at DA0F, then this will serve as a bootstrap code to stored box Pokémon names. CE 206 TM15 Crystal (English) Executes arbitrary code from FA10 (Echo RAM for DA10, which is somewhere in the expanded Balls pocket. D0 208 TM17 Crystal (English) Executes arbitrary code from FA47 (Echo RAM for DA47, which is somewhere in the expanded Balls pocket. D4 212 TM21 Crystal (English) Executes arbitrary code from FA69 (Echo RAM for DA69, which is somewhere in the expanded Balls pocket; like TM21. D8 216 TM25 Crystal (English) Executes arbitrary code from FA69 (Echo RAM for DA69, which is somewhere in the expanded Balls pocket; like TM25. D8 216 TM25 Gold/Silver (English) Executes arbitrary code from FA6A (Echo RAM for DA6A, and DA6A is the least significant Defense EV byte of the second Pokémon in the party. The Speed EVs word follows, and the player can make a jump to somewhere more useful (via C3 yy xx). This may be possible without trading, but getting the exact EVs would be tedious and it would be hard to keep track of them without a memory viewer. Through arbitrary code execution in Pokémon Red, Blue, and Yellow, the second Pokémon may be manipulated to have Defense and Speed EV values that the player desires. E1 225 TM33 Crystal (English) Executes arbitrary code from F418 in Echo RAM (essentially D418); the third character of the fifth enemy Pokémon's nickname. Through arbitrary code execution in Pokémon Red, Blue, and Yellow, the player may rename this Pokémon to include a jump instruction (e.g. to C3 F2 D8 bytes which reads jp D8F2, i.e. jumps to the first item in the item storage system). EF 239 TM47 Gold/Silver (English) Allows the player to offset their position on the map, as documented here.

In Pokémon Ruby, Sapphire and Emerald, Pokémon FireRed and LeafGreen

There are many glitch items in these games named "????????" with no apparent use other than for arbitrary code execution setup. The hex:FFFF "????????" can be distinguished for having the 'return to menu' sprite as its sprite.

These items are available through a double corruption with the Pomeg corruption glitch to force a Pokémon holding one. It is also possible to obtain a ???????? with the Mail and Trick glitches in Japanese Pokémon Ruby and Sapphire.

One way of obtaining them with the Pomeg corruption glitch is through corrupting the in-game trade Pokémon DOTS the Seedot with Defense and Speed EVs spelling out the index number of the desired items with at least 1 HP EV (so it isn't corrupted into an empty space).

In Pokémon Diamond, Pearl and Platinum, Pokémon HeartGold and SoulSilver

These games feature a large number of glitch items which may be nameless.
