This page is split up in a section with simple codes intended for common uses and a section with complex codes for specific uses. Codes are both language specific and version specific, please make sure you select the appropriate code for your language. Likewise, it is advised not to give yourself additional TMs, as to not break the mail writer.
 
'''When a code ends on one or more blank space(s), make sure to manually input these blank spaces one by one to prevent getting an incorrect result.'''

====Making the Mail Writer more convenient====
 
This mail code does the following to improve the use of the Mail Writer:
 
# It overwrites '''the first item in the main item pocket''' to be a TM02.
# It alters data so that using TM02 activates the Mail Writer.
 
After using this code, you can simply use TM02 at any time to start up the mail writer, without requiring any specific party pokémon.
 
Two versions of this code exist. If the MailWriter is currently installed in the TM/HM pocket, please use the leftmost code from the table below. If the MailWriter has already been moved to unused memory (see next section), please use the rightmost code from the table below.
 
Requirements: It is recommended to have an item you do not mind losing in the first slot of the main item pocket. After using this code, it will be overwritten to being a TM02.

====Move the Mail Writer to free up the TM/HM pocket====
 
Executing this code will copy the Mail Writer to an unused area in memory and adjust '''both the TM25 and TM02 bootstrap''' so that it can correctly call the new Mail Writer address. Afterwards, it will set all TM quantities equal to a specific number. '''Please ensure you verify that the newly copied Mail Writer works before saving'''
 
You should have the "MAILWRITER" nicknamed pokémon in the second party slot when using this code, to ensure that you'll also be able to properly activate the MailWriter using TM25.
 
Customization: You can adjust the number in bold to determine how many copies you would like of each TM after moving the Mail Writer. By default the code will set all TM quantities to x01.

====Set up more convenient ACE====
 
'''WARNING: this code is currently planned to undergo a rework due to suspected issues. Until the rework is complete, it is recommended to not use this code.'''
 
This mail code fixes the side effects of duplicate key item swap by removing the last pokémon in the party, along with giving TM33 and setting it up to redirect execution to the mail writer.
 
After using this code, you can simply use TM33 at any time to start up the mail writer, without requiring any specific party pokémon.
 
Note: '''The Korean version of this code will not give TM33. Instead, you can simply use TM15 to start up the RAM writer at will.'''
 
Requirements: Have the glitchmon obtained during duplicate key item swap at the bottom of your party. Have at least one more pokémon in your party.
 
Note: do not use this code if you have already installed the RAM writer.

====Move the Mail Writer to free up the TM/HM Pocket====
 
Executing this code will copy the Mail Writer to an unused area in memory and adjust the bootstrap so that it can correctly call the new Mail Writer address. Afterwards, it will set all TM quantities equal to a specific number. '''Please ensure you verify that the newly copied Mail Writer works before saving'''
 
This code is currently not available for the Japanese releases, since the Japanese version of the Mail Writer does not require specific TM quantities to set up.
 
Customization: You can adjust the number in bold to determine how many copies you would like of each TM after moving the Mail Writer. By default the code will set all TM quantities to x01.

==Changing party pokémon #6's attributes==
 
===Change held item===
 
Changes the held item of party pokémon #6 to the item defined by the mail code. Any item previously held will be overwritten. While any item can theoretically be given, be cautious when changing the held item to a Key Item.
 
Customizability: The value marked in bold determines the held item given to party pokémon. Use [[The Big HEX List|the Big HEX List]] to search what values correspond with specific items.

===Change moves===
 
Using this mail code will overwrite party pokémon #6's moveset using the values defined by the mail code. This will not overwrite the PP values from the previously existing moveset.
 
Customizability: The four value marked in bold correspond to the moves that will be given to the pokémon. First value corresponds with first move, and so on. Use [[The Big HEX List|the Big HEX List]] to search what values correspond with specific items.

===Maximize PP values for all moves===
 
Using this mail code will set the maximum PP of every move, as if a PP Up was used on every move three times. As a limitation of the code, the actual PP values are set to 0 after using this code.
 
Customizability: cannot be customised.
 
Note: Will not replenish current pp values to their new maxima.

===Change OT ID===
 
Using this mail code will alter the original trainer ID of party pokémon #6 to the value defined by the code. Pokémon with OT ID values different from the player will be treated as traded pokémon.
 
Customizability: The values in bold determine the OT ID that party pokémon #6 will recieve. Simply convert the desired OT ID (between 00000 and 65536) to hexadecimal and replace the values in bold. e.g. OT ID '''12345''' corresponds to '''30 39'''.

===Change level===
 
Using this mailcode sets the level of party pokémon #6 to the value defined by the code. It will also automatically update the total experience and battle stats of party pokémon #6 to the appropriate amounts. This code only works for levels 1 through 100. '''Please note that, due to limitations, the game will appear graphically glitchy when it's updating the level. This is temporary and goes away after the code has finished running.'''
 
Customizability: change the value marked in bold with the value corresponding to the desired level.

===Change stat experience===
 
Using this mail code sets the stat experience values of party pokémon #6 to the values defined by the code. The actual battle stats of party pokémon #6 aren't automatically updated after this code. To fix this, deposit to and withdraw the pokémon from the PC.
 
Customizability: the ten values marked in bold determine the stat experience that party pokémon #6 will be set to. These values are divided in groups of two bytes ordered as follows:
# '''FF FF''' - HP
# '''FF FF''' - Attack
# '''FF FF''' - Defense
# '''FF FF''' - Speed
# '''FF FF''' - Special (affects both Sp. Atk. and Sp. Def.)
These values are big endian (most significant byte first). Set them to '''FF FF''' to maximize the stat experience given.

Customizability: the two values marked in bold determine the DVs that party pokémon #6 will be set to. These values are divided and ordered as follows:
# '''FA''' - Attack | Defense
# '''AA''' - Speed | Special
Set to '''FF FF''' to maximize DVs, set to '''FA AA''' for a shiny male pokémon, set to '''2A AA''' for a shiny female (if possible) pokémon.

===Change level, stat experience and DVs in one code===
 
Using this mailcode sets the level, along with stat experience and DVs, of party pokémon #6 to the value defined by the code. It will also automatically update the total experience and battle stats of party pokémon #6 to the appropriate amounts. This code only works for levels 1 through 100. '''Please note that, due to limitations, the game will appear graphically glitchy when it's updating the level. This is temporary and goes away after the code has finished running.'''
 
Customizability: change the value marked in bold on the first line with the value corresponding to the desired level.
 
The first ten values marked in bold on the second & third lines determine the stat experience that party pokémon #6 will be set to. These values are divided in groups of two bytes ordered as follows:
# '''FF FF''' - HP
# '''FF FF''' - Attack
# '''FF FF''' - Defense
# '''FF FF''' - Speed
# '''FF FF''' - Special (affects both Sp. Atk. and Sp. Def.)
These values are big endian (most significant byte first). Set them to '''FF FF''' to maximize the stat experience given.
 
The last two values marked in bold on the last line determine the DVs that party pokémon #6 will be set to. These values are divided and ordered as follows:
# '''FA''' - Attack | Defense
# '''AA''' - Speed | Special
Set to '''FF FF''' to maximize DVs, set to '''FA AA''' for a shiny male pokémon, set to '''2A AA''' for a shiny female (if possible) pokémon.

===Change happiness/time to hatch===
 
Using this mail code sets the happiness value of party pokémon #6 to the value defined by the code. For eggs, this value is instead used to track the amount of egg cycles left before hatching. In order to hatch eggs quickly, make sure to use a value of 01. Due to the way the system is implemented, a value of 00 will instead cause the egg to take an absurdly long time to hatch.
 
Customizability: change the value marked in bold on the first line with the value corresponding to the desired happiness/egg cycles left before hatching.

===Change ID===
 
This mail code sets the player's trainer ID. This will cause the game to treat pokémon caught with the previous, different ID as traded pokémon.
 
Since this code also alters the trainer ID data within saved data, the effect of this code is retained even without saving.
 
Customizability: The values in bold determine the player's new ID. Simply convert the desired ID (between 00000 and 65535, inclusive) to hexadecimal and replace the values in bold. e.g. OT ID '''12345''' corresponds to '''30 39'''.

===Reset obtained status of the Odd Egg (Crystal, non-JP exclusive)===
 
This code resets the event status of the Odd Egg, allowing you to get it again if you've previously obtained it already. Simply execute the code and talk to the Day-Care Man to obtain another Odd Egg. This code can be used indefinitely.

===Give specific Odd Egg (Crystal, non-JP exclusive)===
 
This code instantly gives an Odd Egg, whose species and shininess depends on the value defined by the code. The Odd Egg will be given silently immediately after executing the code.
 
This works even if the Odd Egg was already picked up, using this code will not mark the Odd Egg (given by the Day Care Man) as obtained.
 
====Customizability====
 
By altering the value marked in bold to one of the values in the following table, you can change the contents of the odd egg:
 
{| class="wikitable"
! Species !! Shininess !! Value
|-
! rowspan="2" | Pichu
| Not shiny || 00
|-
| Shiny || 01
|-
! rowspan="2" | Cleffa

|-

|}
 
====Warnings====
 
* Do not use this code if you have a full party.
* You can alter the code to give Odd Eggs corresponding to invalid entries. Do this at your own risk.

==Constant effect codes==
 
By hijacking the OAM DMA routine, we can trick the game into executing a small bit of code on every frame. This allows for certain continuous effects to be applied. Before you can use constant effect codes, you'll first need to execute the following code.
 
===Updating the Mail Writer (compatibility with old setups)===
 
In the past, a code was made to move the Mail Writer from the TM/HM pocket to unused memory. Due to practical limitations, if you used the old moving code (prior to the 2nd of May 2024), installing the OAM DMA Hijack setup will break the Mail Writer.
 
If you fall under this group, you can use the following code to reinstall the Mail Writer in a different location in unused memory that is fully compatible with the OAM DMA Hijack setup. If you are unsure whether this applies to you or not, this code is safe to use under all circumstances. '''Please ensure you verify that the newly copied Mail Writer works before saving'''
 
This code is currently not available for the Japanese releases, since the Japanese version of the Mail Writer does not require specific TM quantities to set up.

===Setting up an OAM DMA hijack===
 
Every frame, the game will execute an OAM DMA routine. The instructions for this routine is kept in HRAM, in the area between $FF80 and $FF89. By inserting a custom jump instruction at the start of this routine, the game will execute custom code during the vblank interrupt.
 
Under normal circumstances, any modifications to the OAM DMA routine would need to be reapplied after every reset. As a workaround, the Special Call ACE exploit is used. Under certain conditions, the game will cue up a Special Call due to story events, for example when Elm calls after beating the 1st gym. As a part of this routine, the game needs to check whether it's allowed to perform the call, since certain calls are only permitted to occur outdoors. By manually setting up invalid call IDs, we can trick the game into executing ACE at the end of every step.
 
After reloading, simply taking a single step restores the OAM DMA hijack setup and reactivates any codes that were previously entered. Due to space constraints, the current setup is designed to have three different "slots", each capable of containing a single code.
 
This code takes care of the Special Call ACE and adds the proper framework for the OAM DMA hijack structure. It only enables the OAM DMA hijack and will not have any immediately visible effects on gameplay. After executing this code, another code needs to be used to insert a custom byte code so that it can be executed on every frame. Codes that do this can be found further on in this section.
 
Due to practical restrictions, the setup for the following versions must take special care of the following:
* French Crystal: the player is not allowed to refight Wilton or Kenji.
* German Crystal: the player is not allowed to refight Wilton or Kenji.
* Japanese Crystal: the setup requires that the pokémon left with the Day Care lady has a specific nickname. The setup automatically applies this nickname. When replacing this pokémon, either make sure the new pokémon uses the nickname "アてがれ" or use the "Reapply the bootstrap" code provided further on the guide.
 
A separate code is provided further on that reapplies the bootstrap, to be used in the case it accidentally gets overwritten.
 
'''Warning:''' if you installed the RAM writer before the 2nd of May 2024, you will need to update it to the latest version before you're able to use these codes.

===1st constant effect slot===
 
Only one of these codes can be active at the same time. Using a second code from this section safely overwrites all preexisting data in slot 1.
 
====Run Button & Walking Through Walls====
 
Executing this code, while an OAM DMA hijack was set up, will trigger the following effects:
* If B is held, the player will run at a faster speed. This speed is equal to Bicycle speed.
* If A is held, the player can ignore (nearly) all collision and walk through walls.
 
If you hold B + a direction on the dpad when transitioning to another map, it's possible that the player's sprite changes to riding a bicycle. This is not an issue, since the code tricks the game into believing the player is riding a bicycle without altering the player's sprite or changing the music. This can easily be fixed by opening and closing the start menu.
 
Due to how this code works, using the Bicycle will not have an effect outside of changing the music.
 
Do not save while surrounded by solid tiles. The OAM DMA Hijack setup will only be activated by taking at least one step after a reset, meaning that you'll be stuck. In case this happens, use the "Manually activate the setup" code down below to be able to escape.
 
'''Warning:''' leaving the boundaries of the current map and entering an undefined map will crash the game. Certain exits, especially indoors areas, rely on player collision to properly function. Make sure to hold B to re-enable collision before appreaching such exits.

====Catch a trainer's pokémon====
 
Executing this code, while an OAM DMA hijack was set up, will trigger the following effects:
* When in a trainer battle, press select. This will turn the trainer battle into a wild encounter battle, allowing you to catch the opponent's current active pokémon.
* Unlike previous versions of this code, the caught pokémon will have the exact same moveset as it did when it was used by the opposing trainer.
* After catching or defeating the current active pokémon, the battle will end. You won't receive prize money, but the trainer will be registered as beaten.

===2nd constant effect slot===
 
Only one of these codes can be active at the same time. Using a second code from this section safely overwrites all preexisting data in slot 2.
 
====Make every wild pokémon shiny or set their DVs====
 
Executing this code, while an OAM DMA hijack was set up, will trigger the following effects:
* Make every encountered wild pokémon shiny. Trainer pokémon are not affected.
 
Customizability: the two values marked in bold determine the DVs that all encountered pokémon will receive. These values are divided and ordered as follows:
# '''FA''' - Attack | Defense
# '''AA''' - Speed | Special
Set to '''FF FF''' to maximize DVs, set to '''FA AA''' for a shiny male pokémon, set to '''2A AA''' for a shiny female (if possible) pokémon.

====Force encounters with a specific pokémon at a specific level====
 
Executing this code, while an OAM DMA hijack was set up, will trigger the following effects:
* All opponent pokémon will be altered to the selected species and the selected level.
* This does not affect any trainer pokémon
* The DVs of this wild pokémon is still randomized like usual, making it possible to shiny hunt it.
 
Customizability: the two values marked in bold determine the species and level that all encountered pokémon will be set to. These values are divided and ordered as follows:
# '''96''' - Pokédex number
# '''46''' - Level
By converting the pokédex number/level of the desired encounter to their hexadecimal equivalents, you can force specific encounters. For example, selecting a pokédex number of $96 (150) and level of $64 (70) will force encounters with a lvl 70 Mewtwo.
 
'''Warning''': this code is not compatible with the "catch trainer pokémon" constant effect. While it will won't cause any harm, the newly caught pokémon's species and level will be overwritten by the previous code.

===3nd constant effect slot===
 
====Enable use of RAM Writer in battle====
 
Executing this code, while an OAM DMA hijack was set up, will trigger the following effects:
* In battle, you select the wrong pocket TM that is used to activate the RAM Writer, the index of the cursor so that pressing A will activate the RAM Writer.
* This counts as using an item, meaning that the opponent's turn starts immediately after closing the RAM Writer.

===Fixing issues===
 
====Reactivate constant effects====
 
When the game sets up a normal Special Call, it will overwrite the invalid call ID that we've set up. Use this code to restore the functionality of the setup.

====Deactivate constant effects====
 
If you no longer wish to use the OAM DMA Hijack setup, you can use this code to simply remove the invalid call ID, deactivating the setup. The remainder of the setup is left intact and can, if needed, easily be reactivated using the previous code.
 
Note that this will not disable any active OAM DMA Hijacks. It is recommended to save and reset after using this code to disable any hijacks that are still active.

===Empty entire party and give a new pokémon===
 
This mail code empties the current party and gives one desired pokémon, as to not leave the player with an empty party. Use this if you get a white screen when opening the party screen. The script to give the new pokémon will only run after you've exited the start screen.
 
Customizability: the values marked in bold correspond to the species and level of the pokémon given, respectively.

==Miscellaneous codes==
 
===Write any value to any address===
 
This mail code allows you to target any address and write any value to it. Note that it can't be used to modify sram (address region $A000 - $BFFF).
 
The first two bytes marked in bold determine the address written to, in low-endian format. E.g. if you wish to target address $DA00, adjust the first two values in bold to '''00 DA'''.
 
The last byte marked in bold determine the value written. Adjust as needed.
