Pomeg data corruption glitch: Difference between revisions

'''Glitzer Popping''' or '''Pomeg corruption glitch''' is a [[glitch technique]] of the "sending out a ??????????" ("Decamark") sub-glitch of the [[Pomeg glitch]] for {{Emerald}}, {{FRLG}} in which the player sends out the [[??????????|Decamark]], views the summary of a Pokémon in the party and scrolls up to access Pokémon in the party beyond slot 6.

The name Glitzer Popping is assumed to have no meaning in itself. It was chosen by the speedrunner werster who was one of the early researchers of the glitch, because he did not want the glitch to have a name which in his opinion would be 'too generic'.

The initial steps for Glitzer Popping in Pokémon FireRed/LeafGreen are the same as in Pokémon Emerald, except that a Pokémon with negative HP must be traded over from Emerald to faint the party since the Pomeg Berry does not reduce HP EVs in these versions.

In {{Emerald}}, the data which the player is able to corrupt with Glitzer Popping is as such:

Glitzer Popping may be used to corrupt the attributes of Pokémon in the Pokémon Storage System. Below are some of the possible techniques for this.

Decaswitch allows a player to perform both Pomeg Glitch and Glitzer Popping without needing Pomeg Berries.

This is a popular exploit of Glitzer Popping that allows the player to hatch any Pokémon in the game, as well as [[glitch Pokémon]] which do not freeze the game after hatching.

In order to know whether the Pokémon is applicable for the glitch and if so; which attribute needs to be converted into a species ID, the player must know the Pokémon's personality value and data substructure (determined by the Pokémon's personality value modulo 24). It is difficult to know a Pokémon's personality value (unless theoretically the Pokémon is a Spinda) without using an external device. For an illustration on how this works, see the [[Glitzer Popping#Pokémon Storage System corruption|section about the mechanics of Pokémon Storage System corruption]] below.

Double corruption is a method of obtaining a Pokémon in the Pokémon Storage System without hatching it. In order to exploit a double corruption, the player should attempt the steps to [[Glitzer Popping#hatch any Pokémon|hatch any Pokémon]] with SEASOR <!--or DOTS?--> until the Pokémon turns into a regular Egg that is either a different Pokémon to the original or remains as Horsea. Afterwards, the player should save the game and continue to make corruptions to the Pokémon in the Pokémon Storage System (resetting if unsuccessful) until SEASOR converts into an unhatched Pokémon.

Pokémon News Reporter corruption is a derivative of using the [[Glitzer Popping#Hatch any Pokémon|hatch any Pokémon]] to obtain a Decamark with an exceedingly long name. When the player speaks with the news reporter in the Pokémon Fan Club of Slateport City's Pokémon Fan Club with a specific Decamark in the first position of the party, it is possible to corrupt data after she mentions the Decamark's name.

Instant Pomeg glitch is a useful trick which allows the player to perform Glitzer Popping from the Pokémon menu without having to enter a battle, by forcing the first Pokémon in the party to be empty.

The new line arrow glitch occurs when a Pokémon has a 'new line' (hex:FB) character in its nickname. This Pokémon may be obtained rarely by performing Glitzer Popping when a Pokémon has the letter "A" as the fourth or eighth character in its nickname.

A method of [[Pokémon cloning]] with the access Pokémon beyond slot six glitch was discovered by Luckytyphlosion in 2014 before it was known that scrolling past those Pokémon will corrupt data. Sometimes in the expanded party there will be a Pokémon that the player can send out. If the player sends this Pokémon into battle and whites out, it is possible for the player to clone the last Pokémon in their party.

Glitzer Popping may be used to sometimes corrupt NPCs on the map if the player escapes from battle using a Fluffy Tail instead of through whiting out.

If the player performs Glitzer Popping on a route with Trainers it can cause corruption of the player's challenge music, and/or corruption of their text (often long instances of "qÁF" in their text) or cause a full red screen. Sometimes after closing the text box (it may take a very long time for to finish printing it) it can cause a battle with a [[glitch Trainer]] to begin.

Glitzer Popping may be used in Emerald and FireRed/LeafGreen to change the coordinates of NPCs on the map. This is useful for accessing behind the Day Care on Route 117 and Four Island in both versions, by encountering a Pokémon in the grass in Route 117 or fishing for a Pokémon in Four Island before scrolling up past Pokémon 255.

Glitzer Popping may corrupt the data of Pokémon in the Day Care in Emerald if the player scrolls beyond stored box data (Pokémon 255-215) while scrolling up.{{clarify}}

Glitzer Popping can be used to corrupt in-game flags either directly through scrolling up past Pokémon 255 or with a derivative trick which involves a glitch Pokémon obtained with the [[Glitzer Popping#hatch any Pokémon|hatch any Pokémon trick]].

Glitzer Popping may rarely set the Fly flag that allows the player to Fly to Evergrande City (where the entrance to Victory Road is and not outside of the Pokémon League) if the player hasn't unlocked it already.

Glitzer Popping may rarely set the flag for an NPC to appear on the second floor of the Pokémon Center and give the player an Eon Ticket. This allows the player to access Southern Island and capture Latios or Latias.

In non-English versions of Pokémon Emerald including the French, German, Spanish and Italian versions of Emerald, it is possible for the player to use Pokémon News Reporter corruption with a specific glitch Pokémon (obtained with Glitzer Popping) to change an address telling the game which Pokémon to send out in battle and activate the flag for access to Faraway Island or Birth Island. More information (in French) may be found [http://pastebin.com/8N9sGwpb here].

Glitzer Popping may rarely affect the player's overworld position and place them in the wrong location (such as in the middle of trees) after escaping with a Fluffy Tail.

Rarely after [[Glitzer Popping#instant Pomeg glitch|instant Pomeg glitch]] is set up, it is possible for the player to Surf on Seaside Cycling Road of Route 110 if they perform the scrolling from one step out of Mauville City's Pokémon Center and walk up.

Glitzer Popping may rarely affect the Secret Base decorations they have in their PC. For example, TheZZAZZGlitch changed Thunder Mat (0x3C) into a 'ÛË ▼ÛË ÀÀÚËÔÀ ÀÀCAN' (0x7C) glitch decoration which acts like a portable two-square hole.

Glitzer Popping ultimately allows for [[arbitrary code execution]] if the player has favourable DMA.

Since the data for Pokémon beyond slot 6 corresponds with unrelated variables, it is possible (listed in the aforementioned [[Glitzer Popping#Exploits|exploits]] section) to corrupt data in a limited number of ways which include:

The variables which are corrupted during scrolling are random due to a mechanism known as [[DMA]]. DMA shifts the location of a memory address to one of 64 locations each time the player performs an action such as opening the Pokémon menu outside of battle, or entering battle. This is the reason why it can take many attempts for a successful Glitzer Popping corruption.

When Glitzer Popping touches a Pokémon's data, it will become a Bad Egg if its calculated checksum and stored checksum do not match.

However, sometimes{{clarify}} it is possible for Glitzer Popping to alter a Pokémon's personality value without the Pokémon becoming a Bad Egg.

After filling the Pokémon Storage System with Eggs and Bad Eggs, any unwanted Eggs and Bad Eggs created from Glitzer Popping can easily be removed with the [[Battle Tower inverse cloning glitch (Emerald)|Battle Tower inverse cloning glitch]] or [[Decamark specific glitches#fast inverse cloning glitch|fast inverse cloning]].

On April 9, 2014 Luckytyphlosion discovered that the glitch could be used to create both Bad Eggs and hatchable Eggs.
