Pomeg glitch
The Pomeg glitch is a glitch exclusive to Pokémon Emerald and Generation IV games.
Performing the glitch
The Pomeg glitch involves using a Pomeg Berry to lower a Pokémon's maximum HP by 2 or more on a Pokémon whose current HP is already very low; because the Pokémon's current HP will be reduced by the same amount as their maximum HP, this can result in the Pokemon's HP dropping to a negative value, which (due to the unsigned manner in which this data is stored) the game interprets as a very high number; for example, if a Pokémon's current HP drops to -1, it will be interpreted as 65,535 and displayed as "?35".
In Generation IV, the glitch still exists but must be performed on a Pokémon with greater than four current HP. (This is still possible if the Pokémon has over 100 EVs in HP, as the Berry will reduce their HP EV to 100; a Lv.50 Pokémon with 240 HP EVs would lose 120 EVs, or 15 HP).
Sub-glitches
Several other glitches derive from the Pomeg glitch, such as the ability to battle with an egg, battling with no Pokémon at all, or battling for an unlimited amount of times. These sub-glitches cannot be performed in Pokémon Ruby and Sapphire.
Battling with no Pokémon
In Generation III
If there is only one Pokémon in the player's party when affected by this glitch, and goes into faint status using a healing item, the player will not white out. This is because the game does not check for this on the field. If the player walks into tall grass and encounters a wild Pokémon or starts a battle in any other way, the Pokémon will be sent out with 0 HP, the Shiny animation will not play, and will faint at the beginning of the battle if it is commanded to attack the opponent, causing the normal whiteout scenario. If on the first turn an item is used to revive the Pokémon the battle will continue as normal.
In Generation IV
Attempting to battle with only a fainted Pokémon in Generation IV will result in a game freeze, unless a trainer in the Battleground or Elite Four is battled, in which case the player will send out a -----. Note that to faint a Pokémon from glitched HP requires the use of a Rare Candy in Generation IV.

Battling with an egg
If the player has only an egg in his or her party with the Pokémon affected, the egg (or rather, the Pokémon that would be inside) can be forced into battle by following the same steps, but putting the egg at the head of the party. The egg will have the same stats it would have upon hatching, as well as all of the moves. This allows it to battle as if it were a normal Pokémon. When battling with an Egg, the sprite of the Pokémon within the egg is displayed; however, there may be irregularity in the coloring of the Pokémon. This may be because the game is reading the backsprite of the Pokémon within the egg and the color palette of the egg itself.
An egg that battles can gain experience in this way, and with patience, level up, learn moves, and even evolve before hatching. However when it hatches the level is set to 5, EVs reset to zero and all EXP gained in the egg is removed. This allows level 5 versions of high-evolutionary Pokémon such as Tyranitar or Dragonite to be obtainable, it also allows otherwise illegal moveset/level combinations, such as a level 5 Staryu with Hydro Pump.
Infinite battle
If the Pokémon that has been affected is sent out with 65,535 HP against an opponent that uses an HP-stealing move like Absorb, the Pokémon's HP will be stolen until it reaches the normal maximum amount, nearly 65,000 HP lower than the glitched amount for a Pokémon with the absolute maximum HP. If a second HP-stealing move is used, the Pokémon will lose its full HP, go down to 0, and then repeat from the top again.

This sub-glitch changes a Pokémon's sprite depending on the moves the affected Pokémon performs or is attacked with.
After performing the Pomeg glitch, the player must enter a battle using a Pokémon under its effect against another that knows one of the correct moves. The second step is letting a turn pass either by use of the Oran Berry on the glitched Pokémon, moves with little or no damage to the foe, or wait for it to use the effective move twice, unless the player's Pokémon has been damaged before. Were this to happen, it is only required to be hit once by the effective move.
Certain moves affect the glitched Pokémon.
Move | Effect |
---|---|
Absorb | Drags sprite towards enemy |
Acid | Enemy sprite goes near Acid and moves with it. |
Air Cutter | Moves the Pokémon from the enemy to the original position of the glitched Pokémon |
String Shot | Moves along the string |
Odor Sleuth | Never ends, screen freezes with the words "Wild/Foe (Pokémon) used Odor Sleuth!" |
Sunny Day | User flies down with the sun's rays. |
Bite | Moves along the bottom Jaw/Teeth. |
Charge | User shrinks to very small size. |
Screech | A orange-white box appears on user and user goes narrower and after this user returns to normal width |
