This is a modified version of [the original tutorial about adding new Pokémon species available in Pokeemerald's wiki](https://github.com/pret/pokeemerald/wiki/How-to-add-a-new-Pokémon-species).

Despite the persistent rumors about an incredibly strong third form of Mew hiding somewhere, it actually wasn't possible to catch it... OR WAS IT?
In this tutorial, we will add a new Pokémon species to the game.

## IMPORTANT: This tutorial applies to Version 1.6.2 and lower.
- [Version 1.7.x onwards](how_to_new_pokemon.md)

# Changes compared to vanilla
The main things that the Expansion changes are listed here.
* Still Front Pics *(`gMonStillFrontPic_YourPokemon`)* and by extension `src/anim_mon_front_pics.c` have been removed.
* `src/data/pokemon/cry_ids.h` doesn't exist anymore.

# The Graphics
We will start by copying the folder containing the sprites for Mewtwo and rename it to `mewthree` (pretty meta huh?):
```sh
cp -r graphics/pokemon/mewtwo graphics/pokemon/mewthree
```
## 1. Edit the sprites
Let's edit the sprites. Start your favourite image editor (I have used GIMP) and change `anim_front.png`, `front.png` and `back.png` to meet your expectations.
__Make sure that you are using the indexed mode and you have limited yourself to 15 colors!__
Put the RGB values of your colors into `normal.pal` between the first and the last color and the RGB values for the shiny version into `shiny.pal`.
Edit `footprint.png` using two colors in indexed mode, black and white.
Finally, edit `icon.png`. Notice, that the icon will use one of three predefined palettes instead of `normal.pal`.

## 2. Register the sprites
Sadly, just putting the image files into the graphics folder is not enough. To use the sprites we have to register them, which is kind of tedious.
First, create constants for the file paths. You'll want to add the constants for your species after the constants for the last valid species.
Edit [include/graphics.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/include/graphics.h):

```diff
 extern const u32 gMonFrontPic_Calyrex[];
+extern const u32 gMonFrontPic_Mewthree[];
```

```diff
 extern const u32 gMonBackPic_Calyrex[];
+extern const u32 gMonBackPic_Mewthree[];
```

```diff
 extern const u32 gMonPalette_Calyrex[];
+extern const u32 gMonPalette_Mewthree[];
```

```diff
 extern const u32 gMonShinyPalette_Calyrex[];
+extern const u32 gMonShinyPalette_Mewthree[];
```

```diff
 //extern const u8 gMonIcon_Calyrex[];
+extern const u8 gMonIcon_Mewthree[];
```

```diff
 extern const u8 gMonFootprint_Calyrex[];
+extern const u8 gMonFootprint_Mewthree[];
```

Now link the graphic files.

Edit [src/data/graphics/pokemon.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/graphics/pokemon.h):

```diff
 const u32 gMonFrontPic_Calyrex[] = INCBIN_U32("graphics/pokemon/calyrex/front.4bpp.lz");
+const u32 gMonFrontPic_Mewthree[] = INCBIN_U32("graphics/pokemon/mewthree/front.4bpp.lz");
```

```diff
 const u32 gMonBackPic_Calyrex[] = INCBIN_U32("graphics/pokemon/calyrex/back.4bpp.lz");
+const u32 gMonBackPic_Mewthree[] = INCBIN_U32("graphics/pokemon/mewthree/back.4bpp.lz");
```

```diff
 const u32 gMonPalette_Calyrex[] = INCBIN_U32("graphics/pokemon/calyrex/normal.gbapal.lz");
+const u32 gMonPalette_Mewthree[] = INCBIN_U32("graphics/pokemon/mewthree/normal.gbapal.lz");
```

```diff
 const u32 gMonShinyPalette_Calyrex[] = INCBIN_U32("graphics/pokemon/calyrex/shiny.gbapal.lz");
+const u32 gMonShinyPalette_Mewthree[] = INCBIN_U32("graphics/pokemon/mewthree/shiny.gbapal.lz");
```

```diff
 //const u8 gMonIcon_Calyrex[] = INCBIN_U8("graphics/pokemon/calyrex/icon.4bpp");
+const u8 gMonIcon_Mewthree[] = INCBIN_U8("graphics/pokemon/mewthree/icon.4bpp");
```

```diff
 const u8 gMonFootprint_Calyrex[] = INCBIN_U8("graphics/pokemon/calyrex/footprint.1bpp");
+const u8 gMonFootprint_Mewthree[] = INCBIN_U8("graphics/pokemon/mewthree/footprint.1bpp");
```

Please note that Calyrex, the Pokémon that should be above your insertion for the time being, reads a "front.png" sprite instead of an "anim_front.png" sprite. This is because currently, Calyrex lacks a 2nd frame. If the front sprite sheet of your species uses 2 frames, you should use "anim_front".

It is also worth to mention that Calyrex's icon sprite is commented out simply because it's currently missing. If you do have an icon sprite sheet present inside your species' folder at `graphics/pokemon`, by all means do not comment entries involving the `gMonIcon` constants.

## 3. Animate the sprites

You can define the animation order, in which the sprites will be shown. The first number is the sprite index (so 0 or 1) and the second number is the number of frames the sprite will be visible.

Edit [src/data/pokemon_graphics/front_pic_anims.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon_graphics/front_pic_anims.h):

```diff
static const union AnimCmd sAnim_Enamorus_1[] =
{
    ANIMCMD_FRAME(0, 1),
    ANIMCMD_END,
};

+static const union AnimCmd sAnim_Mewthree_1[] =
+{
+    ANIMCMD_FRAME(1, 30),
+    ANIMCMD_FRAME(0, 20),
+    ANIMCMD_END,
+};
#endif
```

```diff
SINGLE_ANIMATION(Enamorus);
+SINGLE_ANIMATION(Mewthree);
#endif
```

```diff
 const union AnimCmd *const *const gMonFrontAnimsPtrTable[] =
 {
    [SPECIES_NONE]        = sAnims_None,
    [SPECIES_BULBASAUR]   = sAnims_Bulbasaur,
     ...
    [SPECIES_ENAMORUS] = sAnims_Enamorus,
+   [SPECIES_MEWTHREE] = sAnims_Mewthree,
#endif
     ...
 };
```

Because you are limited to two frames, there are already [predefined front sprite animations](#available-front-animations), describing translations, rotations, scalings or color changes.

Edit [src/pokemon.c](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/pokemon.c):
```diff
 static const u8 sMonFrontAnimIdsTable[] =
 {
     [SPECIES_BULBASAUR - 1]     = ANIM_V_JUMPS_H_JUMPS,
     ...
     [SPECIES_DEOXYS_SPEED - 1]           = ANIM_GROW_VIBRATE,
+    [SPECIES_MEWTHREE - 1]               = ANIM_GROW_VIBRATE,
 };
```

There are also [predefined back sprite animations](#available-back-animations) for the back sprites as well.

Edit [src/pokemon_animation.c](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/pokemon_animation.c):

```diff
 static const u8 sSpeciesToBackAnimSet[] =
 {
     [SPECIES_BULBASAUR]                    = BACK_ANIM_DIP_RIGHT_SIDE,
     ...
     [SPECIES_CHIMECHO]                     = BACK_ANIM_CONVEX_DOUBLE_ARC,
+    [SPECIES_MEWTHREE]                     = BACK_ANIM_GROW_STUTTER,
 };
```

If you want to delay the time between when the Pokémon appears and when the animation starts, you can add an entry to `sMonAnimationDelayTable`

Edit [src/pokemon.c](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/pokemon.c):

```diff
 static const u8 sMonAnimationDelayTable[NUM_SPECIES - 1] =
 {
     [SPECIES_BLASTOISE - 1]  = 50,
     ...
    [SPECIES_KYOGRE - 1]     = 60,
    [SPECIES_RAYQUAZA - 1]   = 60,
+   [SPECIES_MEWTHREE - 1]   = 15,
 };
```

If you want your Pokémon to fly above the ground, you can add an entry to `gEnemyMonElevation`.

Edit [src/data/pokemon_graphics/enemy_mon_elevation.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon_graphics/enemy_mon_elevation.h):

```diff
 const u8 gEnemyMonElevation[NUM_SPECIES] =
 {
     [SPECIES_BUTTERFREE] = 10,
     ...
     [SPECIES_REGIDRAGO] = 5,
+    [SPECIES_MEWTHREE] = 6,
 };
```

## 4. Update the tables

     ...

+    SPECIES_SPRITE(MEWTHREE, gMonFrontPic_Mewthree),
#endif
     ...
};
```

 };
```

    [SPECIES_ENAMORUS]                     = { .size = MON_COORDS_SIZE(64, 64), .y_offset =  0 },
+   [SPECIES_MEWTHREE]                     = { .size = MON_COORDS_SIZE(56, 64), .y_offset = 1  },
#endif
     ...

#endif
     [SPECIES_EGG] = gMonFootprint_Bulbasaur,
 };
```

    SPECIES_PAL(ENAMORUS, gMonPalette_Enamorus),
+   SPECIES_PAL(MEWTHREE, gMonPalette_Mewthree),
#endif
    ...
};
```

Edit [src/data/pokemon_graphics/shiny_palette_table.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon_graphics/shiny_palette_table.h):

```diff

     SPECIES_SHINY_PAL(BULBASAUR, gMonShinyPalette_Bulbasaur),
     ...
    SPECIES_SHINY_PAL(ENAMORUS, gMonShinyPalette_Enamorus),
+   SPECIES_SHINY_PAL(MEWTHREE, gMonShinyPalette_Mewthree),
#endif
     ...
};
```

Edit [src/pokemon_icon.c](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/pokemon_icon.c):

```diff
 const u8 *const gMonIconTable[] =

     ...
    [SPECIES_ENAMORUS] = gMonIcon_Enamorus,
+   [SPECIES_MEWTHREE] = gMonIcon_Mewthree,
#endif
     ...
 };
```

```diff
 const u8 gMonIconPaletteIndices[] =
 {
     [SPECIES_NONE] = 0,
     ...
    [SPECIES_ENAMORUS] = 1,
+   [SPECIES_MEWTHREE] = 2,
    [SPECIES_VENUSAUR_MEGA] = 1,
     ...
 };
```

Here, you can choose between the six icon palettes; 0, 1, 2, 3, 4 and 5. All of them located in `graphics/pokemon/icon_palettes`.

Open an icon sprite and load one of the palettes to find out which palette suits your icon sprite best.

# The Data

Our plan is as simple as it is brilliant: clone Mewtwo... and make it even stronger!

## 1. Declare a species constant

Our first step towards creating a new digital lifeform is to define its own species constant.

Edit [include/constants/species.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/include/constants/species.h):

```diff
 #define SPECIES_NONE 0
 #define SPECIES_BULBASAUR 1
 ...
 #define SPECIES_ENAMORUS 905
+#define SPECIES_MEWTHREE 906

-#define FORMS_START SPECIES_ENAMORUS
+#define FORMS_START SPECIES_MEWTHREE
```

## 2. Devise a name


This name will be displayed in the game. It may be different than the identifier of the species constant, especially when there are special characters involved.

Edit [src/data/text/species_names.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/text/species_names.h):

```diff
 const u8 gSpeciesNames[][POKEMON_NAME_LENGTH + 1] = {
     [SPECIES_NONE] = _("??????????"),
     [SPECIES_BULBASAUR] = _("Bulbasaur"),
     ...
     [SPECIES_ENAMORUS] = _("Enamorus"),
+    [SPECIES_MEWTHREE] = _("Mewthree"),
 };
```

The `_()` underscore function doesn't really exist - it's a convention borrowed from GNU gettext to let `preproc` know this is text to be converted to the custom encoding used by the Gen 3 Pokemon games.

## 3. Define its Pokédex entry

First, we will need to add new index constants for its Pokédex entry. The index constants are divided into the Hoenn Pokédex, which contains all Pokémon native to the Hoenn region, and the National Pokédex containing all known Pokémon, which can be received after entering the hall of fame for the first time.

Edit [include/constants/pokedex.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/include/constants/pokedex.h):

```diff
// National Pokedex order
enum {
    NATIONAL_DEX_NONE,
    // Kanto
    NATIONAL_DEX_BULBASAUR,
...
    NATIONAL_DEX_ENAMORUS,
+   NATIONAL_DEX_MEWTHREE,
};
```

```diff
 #define KANTO_DEX_COUNT     NATIONAL_DEX_MEW
 #define JOHTO_DEX_COUNT     NATIONAL_DEX_CELEBI
#if P_GEN_8_POKEMON == TRUE
-   #define NATIONAL_DEX_COUNT  NATIONAL_DEX_ENAMORUS
+   #define NATIONAL_DEX_COUNT  NATIONAL_DEX_MEWTHREE
```

Do keep in mind that if you intend to add your new species to the Hoenn Dex, you'll also want to add a `HOENN_DEX` constant for it, like this:

```diff
// Hoenn Pokedex order
enum {
    HOENN_DEX_NONE,
    HOENN_DEX_TREECKO,
...
    HOENN_DEX_DEOXYS,
+   HOENN_DEX_MEWTHREE,
...
};
```

```diff
- #define HOENN_DEX_COUNT (HOENN_DEX_DEOXYS + 1)
+ #define HOENN_DEX_COUNT (HOENN_DEX_MEWTHREE + 1)
```

Edit [src/pokemon.c](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/pokemon.c):


```diff
 // Assigns all species to the National Dex Index (Summary No. for National Dex)
 static const u16 sSpeciesToNationalPokedexNum[NUM_SPECIES - 1] =
 {
     SPECIES_TO_NATIONAL(ENAMORUS),
+    SPECIES_TO_NATIONAL(MEWTHREE),
 };
```

Just like before, if we want to insert our new species in the Hoenn Dex, we'll have to do a few extra steps:

```diff
 // Assigns all species to the Hoenn Dex Index (Summary No. for Hoenn Dex)
 static const u16 sSpeciesToHoennPokedexNum[NUM_SPECIES - 1] =
 {
     SPECIES_TO_HOENN(TREECKO),
     ...
     SPECIES_TO_HOENN(DEOXYS),
+    SPECIES_TO_HOENN(MEWTHREE),
 };
```

```diff
 const u16 gHoennToNationalOrder[NUM_SPECIES] = // Assigns Hoenn Dex Pokémon (Using National Dex Index)
 {
     HOENN_TO_NATIONAL(TREECKO),
     ...
     HOENN_TO_NATIONAL(DEOXYS),
+    HOENN_TO_NATIONAL(MEWTHREE),
 };
```

Now we can define the actual text of the Pokédex entry.

Append to [src/data/pokemon/pokedex_text.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/pokedex_text.h):

```diff
 const u8 gEnamorusPokedexText[] = _(
     "Its arrival brings an end to the\n"
     "winter. According to legend, this\n"
     "Pokémon's love gives rise to the\n"
     "budding of fresh life across the land.");

+const u8 gMewthreePokedexText[] = _(
+    "The rumors became true.\n"
+    "This is Mews final form.\n"
+    "Its power level is over 9000.\n"
+    "Has science gone too far?");
```

Finally, we will add the Pokédex entry for Mewthree and link the text to it.

Edit [src/data/pokemon/pokedex_entries.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/pokedex_entries.h):

```diff
 const struct PokedexEntry gPokedexEntries[] =
 {
     ...
     [NATIONAL_DEX_ENAMORUS] =
     {
         .categoryName = _("Love-Hate"),
         .height = 16,
         .weight = 480,
         .description = gEnamorusPokedexText,
         .pokemonScale = 259,
         .pokemonOffset = 1,
         .trainerScale = 296,
         .trainerOffset = 1,
     },

+    [NATIONAL_DEX_MEWTHREE] =
+    {
+        .categoryName = _("NEW SPECIES"),
+        .height = 15,
+        .weight = 330,
+        .description = gMewthreePokedexText,
+        .pokemonScale = 256,
+        .pokemonOffset = 0,
+        .trainerScale = 290,
+        .trainerOffset = 2,
+    },
 #endif
 };
```

The values `pokemonScale`, `pokemonOffset`, `trainerScale` and `trainerOffset` are used for the height comparison figure in the Pokédex. Height and weight are specified in meters and kilograms respectively, while the last digit is the first decimal place.

In Pokémon Emerald, you can sort the Pokédex by name, height or weight. Apparently, the Pokémon order is hardcoded in the game files and not calculated from their data. Therefore we have to include our new Pokémon species at the right places. While the correct position for the alphabetical order is easy to find, it can become quite tedious for height and weight. To find the right position for your Pokémon, you may look at the tables sorted by [height](#pokémon-ordered-by-height) and [weight](#pokémon-ordered-by-weight) respectively in the appendix.

Edit [src/data/pokemon/pokedex_orders.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/pokedex_orders.h):

```diff
 const u16 gPokedexOrder_Alphabetical[] =
 {
     ...
     NATIONAL_DEX_MEW,
+    NATIONAL_DEX_MEWTHREE,
     NATIONAL_DEX_MEWTWO,
     ...
 };

 const u16 gPokedexOrder_Weight[] =
 {
     ...
     NATIONAL_DEX_ESCAVALIER,
     NATIONAL_DEX_FRILLISH,
     NATIONAL_DEX_DURANT,
     NATIONAL_DEX_CINDERACE,
+    NATIONAL_DEX_MEWTHREE,
     //NATIONAL_DEX_PERSIAN, // Alolan Form
     NATIONAL_DEX_DUGTRIO,
     ...
 };

 const u16 gPokedexOrder_Height[] =
 {
     ...
     NATIONAL_DEX_ZERAORA,
     NATIONAL_DEX_GRIMMSNARL,
     NATIONAL_DEX_MR_RIME,
+    NATIONAL_DEX_MEWTHREE,
     // 5'03" / 1.6m
     ...
 };
```

## 4. Define its species information

+        .friendship = 0,
+        .growthRate = GROWTH_SLOW,
+        .eggGroups = { EGG_GROUP_UNDISCOVERED, EGG_GROUP_UNDISCOVERED},
+        .abilities = {ABILITY_INSOMNIA, ABILITY_NONE},
+        .safariZoneFleeRate = 0,
+        .bodyColor = BODY_COLOR_PURPLE,
+        .noFlip = FALSE,
+     },
#endif
 };
```

The `.` is the structure reference operator in C to refer to the member object of the structure SpeciesInfo.

Notice how I also set the ability to `ABILITY_INSOMNIA`, so our little monster doesn't even need to sleep anymore. You can find the abilities for example here [include/constants/abilities.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/include/constants/abilities.h) and here [src/data/text/abilities.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/text/abilities.h).

You can also incorporate a 3rd ability to your species, which is intended to be a [Hidden Ability](https://bulbapedia.bulbagarden.net/wiki/Ability#Hidden_Abilities)!

## 5. Delimit the moveset

Let's begin with the moves that can be learned by leveling up.

Append to [src/data/pokemon/level_up_learnsets.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/level_up_learnsets.h):

```diff
static const struct LevelUpMove sEnamorusLevelUpLearnset[] = {
    LEVEL_UP_MOVE( 1, MOVE_TACKLE),
    LEVEL_UP_MOVE( 7, MOVE_BITE),
    LEVEL_UP_MOVE(11, MOVE_TWISTER),
    LEVEL_UP_MOVE(14, MOVE_DRAINING_KISS),
    LEVEL_UP_MOVE(22, MOVE_IRON_DEFENSE),
    LEVEL_UP_MOVE(31, MOVE_EXTRASENSORY),
    LEVEL_UP_MOVE(41, MOVE_CRUNCH),
    LEVEL_UP_MOVE(47, MOVE_MOONBLAST),
    LEVEL_UP_MOVE( 1, MOVE_SPRINGTIDE_STORM),
    LEVEL_UP_END
};

+static const struct LevelUpMove sMewthreeLevelUpLearnset[] = {
+   LEVEL_UP_MOVE( 1, MOVE_CONFUSION),
+   LEVEL_UP_MOVE( 1, MOVE_DISABLE),
+   LEVEL_UP_MOVE(11, MOVE_BARRIER),
+   LEVEL_UP_MOVE(22, MOVE_SWIFT),
+   LEVEL_UP_MOVE(33, MOVE_PSYCH_UP),
+   LEVEL_UP_MOVE(44, MOVE_FUTURE_SIGHT),
+   LEVEL_UP_MOVE(55, MOVE_MIST),
+   LEVEL_UP_MOVE(66, MOVE_PSYCHIC),
+   LEVEL_UP_MOVE(77, MOVE_AMNESIA),
+   LEVEL_UP_MOVE(88, MOVE_RECOVER),
+   LEVEL_UP_MOVE(99, MOVE_SAFEGUARD),
+   LEVEL_UP_END
+};
#endif
```

Again, we need to register the learnset.

Edit [src/data/pokemon/level_up_learnset_pointers.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/level_up_learnset_pointers.h):

```diff
 const struct LevelUpMove *const gLevelUpLearnsets[NUM_SPECIES] =
 {
     [SPECIES_NONE] = sBulbasaurLevelUpLearnset,
     [SPECIES_BULBASAUR] = sBulbasaurLevelUpLearnset,
     ...
     [SPECIES_ENAMORUS] = sEnamorusLevelUpLearnset,
+    [SPECIES_MEWTHREE] = sMewthreeLevelUpLearnset,
 };
```

Next we need to specify which moves can be taught via TM, HM, or Move Tutor.

Append to [src/data/pokemon/teachable_learnsets.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/teachable_learnsets.h):

```diff
static const u16 sEnamorusTeachableLearnset[] = {
    MOVE_UNAVAILABLE,
};

+static const u16 sMewthreeTeachableLearnset[] = {
+   MOVE_FOCUS_PUNCH,
+   MOVE_WATER_PULSE,
+   MOVE_CALM_MIND,
+   MOVE_TOXIC,
+   MOVE_HAIL,
+   MOVE_BULK_UP,
+   MOVE_HIDDEN_POWER,
+   MOVE_SUNNY_DAY,
+   MOVE_TAUNT,
+   MOVE_ICE_BEAM,
+   MOVE_BLIZZARD,
+   MOVE_HYPER_BEAM,
+   MOVE_LIGHT_SCREEN,
+   MOVE_PROTECT,
+   MOVE_RAIN_DANCE,
+   MOVE_SAFEGUARD,
+   MOVE_FRUSTRATION,
+   MOVE_SOLAR_BEAM,
+   MOVE_IRON_TAIL,
+   MOVE_THUNDERBOLT,
+   MOVE_THUNDER,
+   MOVE_EARTHQUAKE,
+   MOVE_RETURN,
+   MOVE_PSYCHIC,
+   MOVE_SHADOW_BALL,
+   MOVE_BRICK_BREAK,
+   MOVE_DOUBLE_TEAM,
+   MOVE_REFLECT,
+   MOVE_SHOCK_WAVE,
+   MOVE_FLAMETHROWER,
+   MOVE_SANDSTORM,
+   MOVE_FIRE_BLAST,

+   MOVE_TORMENT,
+   MOVE_FACADE,
+   MOVE_SECRET_POWER,
+   MOVE_REST,
+   MOVE_SKILL_SWAP,
+   MOVE_SNATCH,
+   MOVE_STRENGTH,
+   MOVE_FLASH,
+   MOVE_ROCK_SMASH,
+   MOVE_MEGA_PUNCH,
+   MOVE_MEGA_KICK,
+   MOVE_BODY_SLAM,
+   MOVE_DOUBLE_EDGE,
+   MOVE_COUNTER,
+   MOVE_SEISMIC_TOSS,
+   MOVE_MIMIC,

+   MOVE_ENDURE,
+   MOVE_MUD_SLAP,
+   MOVE_ICE_PUNCH,
+   MOVE_SWAGGER,
+   MOVE_SLEEP_TALK,
+   MOVE_SWIFT,
+   MOVE_THUNDER_PUNCH,
+   MOVE_FIRE_PUNCH,
+   MOVE_UNAVAILABLE,
+};
#endif
```

Once more, we need to register the learnset.

Edit [src/data/pokemon/teachable_learnset_pointers.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/teachable_learnset_pointers.h):

```diff
const u16 *const gTeachableLearnsets[NUM_SPECIES] =
 {
     [SPECIES_NONE] = sBulbasaurTeachableLearnset,
     [SPECIES_BULBASAUR] = sBulbasaurTeachableLearnset,
     ...
     [SPECIES_ENAMORUS] = sEnamorusTeachableLearnset,
+    [SPECIES_MEWTHREE] = sMewthreeTeachableLearnset,
 };
```

If you want to create a Pokémon which can breed, you will need to edit [src/data/pokemon/egg_moves.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/egg_moves.h).

## 6. Define its cry
First run these command to copy the Mewtwo sound files:
```sh
cp -r sound/direct_sound_samples/cries/mewtwo.bin sound/direct_sound_samples/cries/mewthree.bin
cp -r sound/direct_sound_samples/cries/mewtwo.aif sound/direct_sound_samples/cries/mewthree.aif
```

In [sound/direct_sound_data.inc](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/sound/direct_sound_data.inc).

```diff
    .align 2
Cry_Enamorus::
    .incbin "sound/direct_sound_samples/cries/enamorus.bin"

+   .align 2
+Cry_Mewthree::
+   .incbin "sound/direct_sound_samples/cries/mewthree.bin"

.endif
```

And linking it in [sound/cry_tables.inc](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/sound/cry_tables.inc). `cry_reverse` in particular is for reversed cries used by moves such as Growl.

```diff
...
    cry Cry_Enamorus
+   cry Cry_Mewthree
.else
```

```diff
    cry_reverse Cry_Overqwil
+   cry_reverse Cry_Mewthree
.else
```

Mon cries are 10512Hz. Make sure to put the aif file in the directory [sound/direct_sound_samples/cries](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/sound/direct_sound_samples/cries)

Higher frequencies may be ruined by compression. To have the cries uncompressed, follow [this](https://github.com/ShinyDragonHunter/pokefirereddx/commit/71ba1c193082817afbed9a8a0ba1d123fffb6f36#diff-e1823f56db7c2344fb9ee843e3c42797f72fa1e108e13a7080018e1db545322eR116) , then clear out the old sound bins

## 7. Define the Evolutions

We want Mewthree to evolve from Mewtwo by reaching level 100.

Edit [src/data/pokemon/evolution.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/pokemon/evolution.h):

```diff
    [SPECIES_SNEASEL_HISUIAN]       = {{EVO_ITEM_DAY, ITEM_RAZOR_CLAW, SPECIES_SNEASLER},
                                       {EVO_ITEM_HOLD_DAY, ITEM_RAZOR_CLAW, SPECIES_SNEASLER}},
+   [SPECIES_MEWTWO]                = {{EVO_LEVEL, 100, SPECIES_MEWTHREE}},
#endif
```

## 8. Easy Chat about your Pokémon


Edit [src/data/easy_chat/easy_chat_words_by_letter.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/easy_chat/easy_chat_words_by_letter.h):

```diff
 const u16 gEasyChatWordsByLetter_M[] = {
     EC_MOVE2(MACH_PUNCH),
     ...
     EC_POKEMON_NATIONAL(MEW),
+    EC_POKEMON_NATIONAL(MEWTHREE),
     EC_POKEMON_NATIONAL(MEWTWO),
     ...
     EC_WORD_MYSTERY,
 };
```

## 9. Make it appear!


Now Mewthree really does slumber in the games code - but we won't know until we make him appear somewhere! The legend tells that Mewthree is hiding somewhere in Petalburg Woods...

Edit [src/data/wild_encounters.json](https://github.com/rh-hideout/pokeemerald-expansion/blob/master/src/data/wild_encounters.json):

```diff
         {
           "map": "MAP_PETALBURG_WOODS",
           "base_label": "gPetalburgWoods",
           "land_mons": {
             "encounter_rate": 20,
             "mons": [
               {
                 "min_level": 5,
                 "max_level": 5,
                 "species": "SPECIES_POOCHYENA"
               },
               {
                 "min_level": 5,
                 "max_level": 5,
                 "species": "SPECIES_WURMPLE"
               },
               {
                 "min_level": 5,
                 "max_level": 5,
                 "species": "SPECIES_SHROOMISH"
               },
               {
-                "min_level": 6,
-                "max_level": 6,
-                "species": "SPECIES_POOCHYENA"
+                "min_level": 5,
+                "max_level": 5,
+                "species": "SPECIES_MEWTHREE"
               },
               ...
        }
```

Congratulations, you have created your own personal pocket monster! You may call yourself a mad scientist now.
