{{Guides header|Wrong pocket TMs and HMs}}
This page serves as a repository for a Wrong Pocket TM ACE setup for the French, German, Italian and Spanish versions of Pokémon Gold & Silver. It is part of the [[Guides:TimoVM's_gen_2_ACE_setups|TimoVM's Gen 2 ACE setups]] set of guides.
The preparation is best done during daytime in-game. If needed, you can change the in-game clock with the help of [https://bl4cksh4rk.github.io/Pokemon-GSC-Clock-Password-Generator/ this tool].
'''Please make sure to fully read every step of the guide before executing them.'''
If you encounter any issues when going through this guide or would like to provide feedback, please contact TimoVM on the [https://discord.gg/EA7jxJ6 Glitch City Research Institute Discord].
=Setting up initial ACE=
In the generation 2 games, items are stored in their own dedicated compartiments. All TMs and HMs are stored in their own pocket, all key items are kept in their own pocket, etc..
By glitching an item into a pocket that it's not supposed to be, we can use the item to
TM25, in particular, executes code starting from $FA6A, a
In practice, the initial ACE setup will be created using the following general process:
Line 20 ⟶ 27:
# Use the bad clone to obtain two additional bicycles. then use [[Duplicate key items glitch|duplicate key items glitch]] to place TM25 (an ACE item) in the ball pocket.
===A note on the side effects of the method described below===
The method described on this page requires fairly heavy abuse of glitches that will produce a small amount of side effects. All these side effects can be fixed with later applications of ACE and are never permanently harmful for the game:
Line 29 ⟶ 36:
Later parts of the guide will offer methods to fix these side effects.
===Requirements for this guide===
'''When playing on original cartridge or on emulator, it is absolutely required to have used the Clear Save Data feature (press SELECT + UP + B on the title screen) or have replaced the battery at least once since owning the game.'''
Line 35 ⟶ 42:
* We'll require a pokémon that has exclusively defeated a set of specific encounters within '''Union Cave and route 33'''.
* Completing the setup requires having reached Goldenrod City, to access the Day Care and the GoldenRod Dept. Store.
* Due to technical reasons, please ensure that the following is true for your trainer ID:
** Your trainer ID must not be equal or higher than 65280.
** The remainder after dividing your trainer ID by 256 must not be equal to 255.
* If your trainer ID does not fulfill both requirements, one of the methods described in the guide will not work correctly. When starting from a new save, it is recommended to reset your game until you get a compatible trainer ID. If you do not wish to reset your save, a workaround is provided that requires you to not have traded the Machop in Goldenrod City yet.
==Step 1:
# Either
# Have it fight the following pokémon and defeat them
#* Rattata - Union Cave, Route
#* Hoppip -
#* Hoppip -
# Have it fight the following pokémon with the help of exactly one other pokémon ('''the experience must be shared between exactly two party pokémon''')
#* Onix - Union Cave
# The "BOXCODES" nicknamed pokémon must never gain experience from any other battle from this point onward
==Step 2: Obtaining a bad clone through resetting while saving==
A bad clone is created when you reset the game at a very specific time frame where:
Line 69 ⟶ 66:
In combination with the Day Care, we can turn this bad clone into a glitch pokémon that we'll be using to perform a variety of glitches.
===Requirements===
* A box that has never been completely full at any point in the past.
* Fill this box with 15 pokémon. You can use [[Pokémon cloning (Generation II)|cloning glitch]] to obtain the required pokémon.
* An additional pokémon that you can deposit to the PC.
===Obtaining the bad clone===
# Deposit any party pokémon to the current active box.
# Go to "Move pokémon w/o mail", you will get a prompt to save the game.
# '''Reset the game''' shortly after the "saving...” text is fully printed
# If successful, upon restarting the game you will find a level 0 female version of the deposited pokémon with a glitched name. '''Make sure you only withdraw this pokémon to your party using "Move pokémon w/o mail" to keep it at lvl 0.'''
Line 89 ⟶ 86:
Use these guidelines and keep retrying until you've obtained a bad clone.
==Step 3: Obtaining additional bicycles and getting TM25 in the ball pocket==
This works in any language version on any generation 2 game, the method is based on a translation of a [[https://nakayoshibaddi.hatenadiary.jp/entry/2017/08/15/223932 blogpost from 任意コード]].
This method will only work if your trainer ID fulfills both of the following requirements:
* Your trainer ID must not be equal or higher than 65280.
* The remainder after dividing your trainer ID by 256 must not be equal to 255.
If your trainer ID does not fulfill both requirements and you do not wish to reset your save, please follow the following steps:
# On route 34, catch a Drowzee.
# On the 5th floor of the Goldenrod Dept. Store and trade Drowzee for a Machop.
# Buy a TM48 (Fire Punch) and teach it to Machop. Rearrange its moves so that Fire Punch is in the second move slot.
# Using the [[Pokémon cloning (Generation II)|cloning glitch]], get at least six copies of Machop (it is recommended to keep some spares just to be safe). We'll be using these Machop in the remainder of the setup.
===Requirements===
Have the following items in the ball pocket:
Line 106 ⟶ 111:
Have the following pokémon in the party:
{| class="wikitable" style="margin-left: auto; margin-right: auto; border: none;"
! Compatible trainer ID !! Incompatible trainer ID
|-
|
1. Bad clone
2. Drowzee with Fire Punch in second move slot
3. Drowzee with Fire Punch in second move slot
4. Unwanted pokémon
5. Unwanted pokémon
6. Unwanted pokémon
||
1. Bad clone
2. Traded Machop with Fire Punch in second move slot
3. Traded Machop with Fire Punch in second move slot
4. Traded Machop
5. Traded Machop
6. Traded Machop
|}
You can buy the TM for Fire Punch at the Goldenrod Dept. Store. To save on time and money, catch one Drowzee (50% encounter odds all day on route 34) and teach it Fire Punch, then clone it using [[Pokémon cloning (Generation II)|cloning glitch]].
Have the following pokémon in the box:
{| class="wikitable" style="margin-left: auto; margin-right: auto; border: none;"
! Compatible trainer ID !! Incompatible trainer ID
|-
|
- 1 unwanted pokémon
- 1 normal pokémon
||
- 1 Additional traded Machop
- 1 normal pokémon
|}
Keep in mind that we'll be corrupting both the Drowzees and the unwanted pokémon. Make sure to only use pokémon you do not wish to keep. The normal pokémon will not be corrupted at all during this process.
===Obtaining duplicate bicycles===
# Deposit the bad clone in the daycare and retrieve it. '''It will now have turned into a glitch pokémon'''. Arrange your party as follows:
## Glitch pokémon
## Drowzee/traded Machop with Fire Punch in second move slot
## Drowzee/traded Machop with Fire Punch in second move slot
## Unwanted pokémon/traded Machop
## Unwanted pokémon/traded Machop
## Unwanted pokémon/traded Machop
# Using "move pokémon w/o mail", add the stored unwanted pokémon/additional traded Machop to the top of your party. This will push the glitch pokémon down to the second slot.
# Switch the
# Select "Deposit pokémon" from the PC and deposit the top two pokémon in your
# Withdraw the normal pokémon from your box and add it to the party using "Withdraw pokémon".
The party will now contain two Drowzee/Machop that will both be holding a bicycle each. Take these held items to add them to the bottom of the Key Item list. '''It is now safe to save.'''
===Obtaining TM25===
# Go to the bottom of the key item list. The bottom of the list should consist of three separate bicycles.
Line 146 ⟶ 170:
Do not worry about the glitch pokémon that's still in your party or the key item list that lacks a cancel button, we'll fix both at a later point in time.
==Step 4: How to execute ACE using TM25==
Now that we have obtained TM25 outside of the TM/HM pocket, we'll need to set up everything needed to actually safely use it. TM25's effect is to execute code starting from party pokémon #2's stat experience data. What we'd like to do is to redirect it such that box names get executed instead:
Line 155 ⟶ 179:
===Finishing the setup===
# Arrange your party like the following:
## Any
## "BOXCODES" nicknamed Pokémon that has defeated a specific set of pokémon
## Any
## Any
## Any
## Glitch pokémon used in part 3<sup>1</sup>
# Finally, give the "BOXCODES" nicknamed pokémon a flower mail with the following language-specific content:
{| class="wikitable" style="margin-left: auto; margin-right: auto; border: none;"
! French !! German !! Italian !! Spanish
|-
|
[[File:Mail French GS.png]]
||
[[File:Mail German GS.png]]
||
[[File:Mail Italian GS.png]]
||
[[File:Mail Italian GS.png]]
|}
<sup>1</sup> This last pokémon is not strictly needed for the setup, but is placed here in order to remove it from the party with a later box name code. If you do not wish to remove it, simply replace it with an unwanted pokémon.
Line 181 ⟶ 218:
|}
==Step 5: Using Wrong Pocket TM25 ACE==
In order to use ACE, always perform the following steps:
Line 199 ⟶ 236:
'''Anytime you wish to execute wrong pocket TM25 ACE, make sure the "BOXCODES" nicknamed pokémon is in party slot #2 and the held mail was read before using TM25.'''
=
While we now have a way to execute box name codes using ACE, the current setup has a few drawbacks:
* Executing ACE requires reading a mail before every execution
* Box name codes have a limited characterset, effectively meaning that it's difficult to set up more complicated ACE effects.
To resolve this issue, we're going to install the Mail Writer. This is a 50 byte program, installed as a series of TM quantities, that will allow us to quickly and efficiently write and execute any arbitrary code we want.
To do that, we're going to use a box name code to obtain 255 copies of all TMs, then sell them in specific quantities to write out a program. Alongside that, the box name code will also alter a party pokémon's data. This will allow us to use the Mail Writer with TM25, as long as this pokémon is kept in the second party slot.
The mail writer itself will be installed in the TM/HM pocket through the following two step process:
# Execute a box code using Coin Case ACE that sets the quantities of all 50 TMs to x255, as well as placing a TM25 in the main item pocket. On top of that, it will modify the data of party pokémon #3 so that TM25's effect gets redirected to the start of the TM/HM pocket, as long as it is kept in the second party slot.
# Sell TMs in specific quantities so that the amount of TMs in the TM/HM pocket spell out a small mail writer program.
==Step 6: Setting all TM quantities to x255==
* Rename box names to form the following language dependent codes. '''Please mind the differences between uppercase X ([[File:Character UCX.png]]), lowercase x ([[File:Character lcx.png]]) and multiplication symbol ([[File:Character mul.png]])'''.
{| class="wikitable" style="margin-left: auto; margin-right: auto; border: none;"

[[File:Box Italian GS Setup.png]]
||
[[File:Box Spanish GS Setup.png]]
|}
* Catch any pokémon and nickname it "MAILWRITER". '''Put it in the third party slot'''. We'll alter this pokémon's stat experience to redirect TM25 execution to the TM/HM pocket
* Ensure that you have everything set up for Wrong Pocket TM25 ACE:
** "BOXCODES" nicknamed pokémon holding mail in party slot #2
** Read the correct mail beforehand
* Use TM25 once. If the code was executed successfully, switch to the TM/HM pocket. '''It should now contain every TM at a quantity of x255.'''
'''NOTE: due to limitations, the German version of this box code can only be used once'''. If you need to use it again, make sure to redo box 7's name.
==Step 7: Selling TMs to form a program in the TM/HM pocket==
Now that we have obtained x255 of every TM, we'll be selling specific amounts of these in order to form a program. This program differs slightly depending on the specific language you're using. The following table displays how many TMs of each kind you need to end up with, along with the amount of money you gain by selling them.

===Running the newly written program===
* It is recommended to save before continuing.
* Put the pokémon that was nicknamed "MAILWRITER" into the 2nd party slot.
* Use TM25. If everything went correctly, this will start the mail writer and open a screen asking you to input text for a mail.
* From now on, you can repeat this process at any time to start the mail writer.
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 the "MAILWRITER" pokémon. This can be done using the box codes included a bit further below.
A note on the nicknamed pokémon: when running the box name code, we altered "MAILWRITER"'s stat experience data to contain a redirect to the TM/HM pocket. You can safely deposit and withdraw it from the PC. '''Please note that this pokémon must never gain experience after this point, otherwise you'll need to reapply the setup.'''
==Step 8: Using the mail writer==
'''From now on, simply go through the necessary steps to use TM25 to start up the RAM 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 screen just to the right of the lower row. This can be used to verify if a code was entered correctly.
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.
===Controls===
Between entering mail codes, the mail writer will ask for user input.
* '''Press SELECT''' to open a new mail and continue writing data.
* '''Press START''' 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.
{| class="wikitable" style="margin-left: auto; margin-right: auto; border: none;"
| [[File:Mail writer write mode.png|288px]] || [[File:Mail writer input mode.png|288px]]
|-
| Enter your mail code, then press "END". || It prints the checksum and waits for input.
|}
==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.
=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
*# "BOXCODES" pokémon holding mail
*# "MAILWRITER" pokémon
*# 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]])'''.

* Read the mail held by the "BOXCODES" pokémon
* Use TM25 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, the "MAILWRITER" nicknamed pokémon has now been repaired.

==In-depth explanation of the setup==
===Effect of party pokémon #3===
Defeating the provided list of pokémon will result in the following values at the following addresses, assuming the pokémon is in party slot #2:
<pre>
DA65 00 nop
DA66 75 ld [hl], l
DA67 00 nop
DA68 94 sub a, h
DA69 00 nop
DA6A C3
DA6B 00
DA6C CF jp $CF00
DA6D 00 nop
DA6E 6E ld l, [hl]
</pre>
Using TM25 will cause execution to jump to $DA6A, after which execution will immediately jump to $CF00, which is in the middle of the last buffered mail.
===Effect of the mail===
The last read mail is buffered from $CEED onward. Converting the characters from the mail to assembly results in the following, ordered by language:
<pre>

===Effect of the setup box name code===
Converting the characters from box names to assembly results in the following code. Please note that the box name code overwrites part of itself, the translated assembly assumes the code was already used once.
The code overwrites part of itself to call the byteFill function. This will fill the area between $D57E and $D5AF with $FF values, setting all 50 TM quantities to 255. Separately, this code overwrites the latter half of party pokémon #5's stat experience data, allowing it to function as a TM25 bootstrap that redirects execution to the Mail Writer.
