The Nickname Writer allows you to easily write and execute arbitrary payloads. You can either make and execute your own codes, or head to the [[Guides:Nickname Writer Codes|Nickname Writer codes]] page. This page contains a collection of assembly for nickname codes that can be used for a variety of common purposes such as editing pokémon and items, editing player stats, resetting legendaries etc..
 
=Addendum: raw text transcripts of nickname codes=
 
These are provided as an alternative in case images fail to load.

=Addendum: technical explanation of the setup=
 
==Nickname Converter Item Code==
 
===Explanation===
 
The item code itself consists of two components. The first 10 items are used to write a program that takes text characters from the nicknames of characters currently within the active box, converts them, then writes the resulting values to unused memory starting from $D66A.
 
Pairs of text characters are converted to single values through a [(2a + b)%256] formula, where a is the value of the first character and b the value of the second. text terminators are skipped, the code will stop and execute the newly written code once it either reads a $00 value or if values are being read past $DEFF.
 
<pre>
11 6F D6 ld de, UNUSED_MEMORY ; Memory between $D66F and $D6F4 goes unused
D5 push de
21 0B DE ld hl, wBoxNicks
.loop
2A ldi a, (hl)
03 inc bc ; Filler, no effect on flags
87 add a
0B dec bc ; Filler, compensates previous inc bc, no effect on flags
30 04 jp nc, .notChar ; Aside from space (should not be used), "add a" will only give nc if value read is not a text char
86 add a, (hl)
12 ld (de), a
2C inc l ; Affects z flag
13 inc de
.notChar
20 F4 jp nz, .loop ; Loop unless l rolled over to $00 or value read was $00
C9 ret ; Due to previous push de, this ret will cause execution to resume from $D66A onward, immediately running the newly written code
</pre>
 
The last item, the Leaf Stone, simply form a pointer to $F32F. Due to echo RAM this address is equivalent to $D32F, which correspond to item #6's item ID, the start of the item code. By replacing the map script pointer with this item, we can redirect the map script routine to execute the item code instead. This routine is executed on every frame, as long as the start menu isn't open.

==Infinite Eevee Nickname==
 
===Explanation===
 
The Infinite Eevee mode nickname writes $00 to the lower byte of wMissableObjectList, causing a misalignment in how the game applies NPC disappearance, causing Eevee's pokéball to stay permanently visible until the game is reset or the player leaves the Celadon Mansion penthouse.
 
<pre>
AF xor a ; a = $00
EA D2 D5 ld (wMissableObjectList), a ; Misaligns which objects are made invisible
C9 ret
</pre>
 
===Raw Assembly===
 
<pre>
AF EA D2 D5 C9
</pre>
 
==4F Boostrap Nicknames==
 
This set of nicknames, when converted, will modify item #1's ID to be 4F and writes a bootstrap so that using it will lead to execution of the item code from $D328 onward. It requires the presence of the Infinite Eevee Mode Nickname (see previous section) to properly return.
 
<pre>
3E 59 ld a, $59 ; 4F's item ID
21 22 D3 ld hl, wBagItems ; item #1's ID
22 ldi (hl), a
AF xor a ; a = $00
22 ldi (hl), a
22 ldi (hl), a
22 ldi (hl), a
22 ldi (hl), a ; clears a bunch of $FF values placed by swapping party pokémon
21 64 DA ld hl, 4F_Execution_Pointer
3E 21 ld a, $21
22 ldi (hl), a
3E 2E ld a, $2E
22 ldi (hl), a
3E D3 ld a, $D3
22 ldi (hl), a
36 E9 ld hl, $E9
; The contents of the first nickname (see previous section) are written right after this, ensuring safe return.
</pre>

3E D3 22 36 E9
</pre>
 
==Using 4F==
 
===Explanation===
 
Using 4F, an invalid item, will cause the game to index the item effects table out of bounds, leading to an invalid execution pointer. For 4F, this causes the game to execute code from $FA65 onward. Due to echo RAM, this address is equivalent to $DA65. Thanks to the bootstrap that was applied earlier, this will then cause the game to jump to $D328, corresponding to the start of the item code.

==Nickname Writer==
 
===Explanation===
 
The Nickname Writer is a small program that, using nicknames as input, is able to write arbitrary amounts of custom code relatively quickly. It first request a nickname as input, then converts that data to custom code, then displays a checksum of the written data and finally asks the player to provide additional input.
 
The value of the checksum is calculated by [($80 + the sum of all written values)%256]. Custom code is buffered and executed within enemy party data. Due to how it calls DisplayNameRaterScreen, it will also nickname a party pokémon corresponding to the item slot that 4F currently occupies.

==Cleanup Code (new save)==
 
===Explanation===
 
This code cleans up every negative side effect brought on by the setup and allows the player to continue the story as intended, with the exception of 4F being added to the item bag, enabling use of the Nickname Writer.
 
The negative effects targeted are:
* By picking up Eevee, we have flagged its poké ball as "obtained"
* The current active box is filled with nicknamed Eevees
* The item pack currently has 255 items
* The item code is currently still required to run the Nickname Writer
* We currently have two badges set as obtained
* Our pokédex currently has 152 pokémon species caught, preventing the story from continuing
* Setting up SRAM glitch has given us a party of 255 pokémon
* We are currently located in the Celadon Pokémon center, while we need to return to Pallet Town to pick up the starter pokémon

==Cleanup Code (existing save)==
 
===Explanation===
 
This code cleans up every negative side effect brought on by the setup and allows the player to continue the story as intended, with the exception of 4F being added to the item bag, enabling use of the Nickname Writer.
 
The negative effects targeted are:
* By picking up Eevee, we have flagged its poké ball as "obtained"
* The current active box is filled with nicknamed Eevees
* The item pack currently has 255 items
* The item code is currently still required to run the Nickname Writer
 
Since existing saves do not have to set up SRAM glitch, there are a lot less side effects that need to be addressed by the cleanup code.
