→Step 5: Finishing the Mail Writer
Line 114:

Once this is done, you have completed the setup and have installed the Mail Writer. You can now simply use TM15 at any time to start up the Mail Writer, regardless of your location or the pokémon in your party.
===How the mail writer works====
Upon execution, the Mail writer will open the mail character entry screen where the player can write up to 32 different characters. After the player has confirmed the mail, the following actions take place:
* The Mail writer will take pairs of characters and convert them into a single combined value. These values are then sequentially written, converting the 32 letter mail into a 16 byte long line of code.
* Next, the Mail writer will display a checksum calculated from the combined value of all written bytes for the player to verify. Then the program enters a waiting state where they can either choose to write another mail, go back and correct previously written values or stop the mail writer and execute the newly written payload.
* If the player has chosen to write a new mail, the Mail writer will open a new mail entry screen. The new mail is then also converted into a 16 byte lond line of code and placed right after the code written by the previous mail(s), allowing the player to write arbitrarily long payloads.
==Step 6: Using the Mail writer==
The mail writer will open a screen that asks you to write the contents of a mail. This is where you'll need to enter mail codes. Once done, use the "END" option to finish the mail.
This will cause the mail writer to convert the newly written code into assembly. It will also '''print a checksum''' (sum of all written values) on the lower left corner of the screen. This can be used to verify if a code was entered correctly.
Assembly can easily be converted to mail codes using [https://scotteh.me/ace/mail/ Scotteh's mail writer tool]. 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. A list of ready-to-use codes will be provided at the end of the guide.

===Controls===
Between entering mail codes, the mail writer will ask for user input.
* '''Press A''' to open a new mail and continue writing data.
* '''Press B''' to immediately jump to and start executing the newly written program. '''Only use this when you've finished every mail.'''
* '''Press any other button''' to go back one byte at a time to correct errors. '''If the printed checksum doesn't match the expected checksum, press DOWN 16 times to retry the last mail.''' This will also overwrite the printed checksum with the value at the currently selected address, giving you a method to check how far back you're going.
'''Due to space limitations, it is not possible to exit the Mail Writer without executing the newly written code. If you accidentally start the Mail Writer, you can safely exit by writing a mail with the contents "セス" and execute it.'''
=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 editing pokémon, obtaining 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.
