Now that we have the Coin Case, we'll need to set up everything needed to actually safely use it. Using a specific setup, we can force the Coin Case to execute code starting from the second character of the last read mail. From here, we need to ensure that we have the proper setup to execute box name codes. |

Due to the limited characterset, the box name code rewrites part of itself to be able to achieve its effect. This will cause the box names to appear glitched after executing Coin Case ACE once. |

From now on, you can repeat this process at any time to start the mail writer. Since we aren't planning on using the Coin Case anymore, the mail that was previously give to a pokémon can be removed. It is no longer relevant for the remainder of the setup. |
|||
If the game crashes, first recheck if all TM quantities are correct. If all quantities are correct, you may need to redo the setup for TM33. This can be done using the box codes included a bit further below. |
|||
'''The next section will elaborate on the usage of the Mail Writer. Please read these instructions carefully before proceeding.''' |
|||
===Troubleshooting & repairing TM33=== |
|||
If the game crashes, first recheck if all TM quantities are correct. If all quantities are correct, you may need to redo the setup for TM33. This can be done using the following box code: |
|||
'''Please mind the differences between uppercase X ([[File:Character UCX.png]]), lowercase x ([[File:Character lcx.png]]) and multiplication symbol ([[File:Character mul.png]])'''. |

|||
To execute this box name code, repeat the process for Coin Case ACE: |
|||
* Read the mail previously given to a party pokémon. |
|||
* Go to the Goldenrod Radio Tower and follow the correct steps to finish the setup. |
|||
* Use the Coin Case to execute the code. If the game crashes, doublecheck the box name code and ensure you've performed every step of the process correctly. |
|||
* If the code executes succesfully without crashing the game, TM33's functionality has now been repaired. |

Due to a lack of available memory in the TM/HM pocket, it is not possible to quit the RAM writer without executing the newly written code. '''If you ever accidentally activate the mail writer and would like to quit, simply write a mail containing "Rh", then confirm and exit the RAM writer.''' |

Assembly can easily be converted to mail codes using [https://timovm.github.io/MailConverter/ TimoVM's MailConverter]. Simply paste the assembly of the code you wish to enter here, press "run" and the converter will automatically generate mail codes requiring the least amount of button presses to write. |

Since the mail writer is written using TM quantities, using or gaining TMs will break the mail writer. Because of this, we'll use the mail writer to execute a small code that achieves the following: |
|||
* Copies the mail writer to unused memory |
* Copies the mail writer to unused memory |
||
* Overwrite the existing quantities in the TM/HM pocket to x1 for every TM |

After executing this code, attempt to start up the mail writer. If you are able to open it and are able to successfully execute the following blank mail, the copy has finished successfully and you can save the game. |
|||
==What to do with the Mail writer== |
|||
The Mail writer allows you to easily write and execute arbitrary payloads. Aside from writing your own codes, we recommend the following: |
|||
* [[User:TimoVM/Mail Writer Codes|Mail codes]]: this page contains a collection of assembly for mail codes that can be used for a variety of common purposes such as fixing the side effects of the ACE setup, editing pokémon and items, etc.. |
|||
* [[User:TimoVM/RAM Writer|RAM writer]]: (recommended for more experienced users) this page contains the assembly for a large one-size-fits all program that allows you to edit any value in RAM with a user-friendly GUI. It will also fix the side effects of the ACE setup when you first run it. WARNING: THE RAM WRITER SETUP FOR GOLD/SILVER IS CURRENTLY BEING REDESIGNED. PLEASE DO NOT INSTALL YET. |
|||
=Addendum: repairing the "MAILWRITER" pokémon= |
|||
In case something happens with the "MAILWRITER" nicknamed pokémon that causes it to no longer function, you can repair the pokémon without having to reset TM quantities using the following procedure: |
|||
* Arrange the party as follows: |
|||
*# Any |
|||
*# Any |
|||
*# "MAILWRITER" pokémon holding mail |
|||
*# Any |
|||
*# Any |
|||
*# Any |
|||
* Enter the following language-specific box name. '''Please mind the differences between uppercase X ([[File:Character UCX.png]]), lowercase x ([[File:Character lcx.png]]) and multiplication symbol ([[File:Character mul.png]])'''. |

Box name data starts from $D8BF onward. Converting the provided mail code to assembly results in the following: |

|||

|||
