Building the full RAM writer
We will be installing the full RAM writer using a series of mail codes. These mail codes will be assembled using Scotteh's mail code tool. Copy paste the entire code in the text box on the mail code tool's page, then press "Run".

After you press run, the tool will generate the mail codes that you need to enter in the mail writer.
After entering every code, a new number will appear to the right of the bottom mail row. This is a checksum and is used to verify that you've correctly entered every mail. If a checksum doesn't match the one given by the tool, that means that a code was incorrectly entered, meaning you will need to redo your mail by pressing DOWN enough times (16 times if you’ve entered a full mail code) to return to the starting byte of the last mail, then entering that same mail again.
After you're finished entering all mail codes, you can press B during the user input phase in order to start up the full RAM writer.
Using the full RAM writer
After you're finished and have verified that all checksums were valid, press B during the user input phase in order to start up the full RAM writer.
Running the RAM writer for the first time will activate the following single use effects:
- Save the RAM writer to the contents of box 14.
- Add TM33/TM17 to the key item pocket, along with restoring the cancel button.
- Install setup to make sure that using TM33/TM17 from the item pack will start the RAM writer.
- Automatically start the RAM writer.
For Gold & Silver, it will have the following additional single use effects:
- Remove the last pokémon from the party.
- Restore the CANCEL button of the key item pocket.
- Reorganize the ball pocket to only contain TM17.
Starting the RAM writer, either automatically or through using wrong pocket TM33, will activate the following effects:
- Copy the necessary data to memory to activate the RAM writer.
- Deploy setup that will enable the use of TM33/TM17 during battle.
- Start the RAM writer.
After the full RAM writer has successfully started, press START to quit the RAM writer and make sure to save your game.
After exiting the RAM writer, you can restart the RAM writer by using TM33 from the item pack. In battle, you can activate the RAM writer by using TM33 and selecting "QUIT". Please note that the setup to enable the use of TM33 during battle does not persist between resets, you can reenable this function by using the RAM writer outside of battle at least once.
As you can see in the screenshots below, the RAM writer will draw various values on the screen. The leftmost 4 columns describe the addresses that are currently in view. The rightmost two columns describe the values at each of these addresses. All values on screen are represented in hexadecimal format.
For example: DA01>05 means that the address $DA01 is currently holding the value of $05.
For a list of useful addresses and how to change them to achieve a desired effect, by visiting [Google Sheets document] and making a local copy, you can edit the values and determine what values you need to write at specific addresses to get that effect.
Let's go over the controls of the full RAM writer. By default, the RAM writer will open in Read mode.
Full Writer Controls
The RAM writer uses two modes of operation. In Read mode you are able to navigate memory and view the values at specific addresses. in Write mode you'll lock in a single address and manipulate the value at that address.
