Project Pokémon Bot

This game was distributed to players of Pokémon Colosseum via the Japanese Bonus Disc.
The event itself was actually programmed into the Pokémon Colosseum game, as seen here with the English version of the unreleased event.

In Pokemon Omega Ruby & Alpha Sapphire, after the player clears the first Contest Spectacular,
the player can obtain a Cosplay Pikachu from a Pokemon Breeder in Slateport City Contest Hall.

While it can be traded via local or online trade,
it cannot be traded using Wonder Trade, Global Trade System, and cannot be deposited into Pokemon Bank.
(which means it cannot be transferred up to the later generations)

This gift was distributed via Serial Code to players who preordered the movie tickets to M22: Mewtwo's Counterattack Evolution in Japan.
This gift comes with 200 in every AV stat. Additionally 3 out of 6 IV stat are 31, and the rest have the value of 30.
The Trainer ID signifies the date of M01: Mewtwo Strikes Back's first release in Japan: July 18th, 1998.
* Interestingly, there are bitflags that indicates that 2 additional (unknown) games are eligible to receive this wonder card. Maybe they're testing it on Sword & Shield?
(Note: The event redemption period ends before Sword & Shield is released, though)
Thanks @wo0ts for his contribution!

For Pokémon Ruby and Sapphire, the paired games had an exclusive feature that allowed them to scan e-Reader Cards and obtain a special berry.
Pokémon holding these berries were not allowed to be traded to other main series games.
Pokémon holding these berries were also not allowed to be traded to Colosseum or XD, nor transferred to Pokémon Box: Ruby and Sapphire.
Once you scanned the e-reader card (or injected the berry card data), you can collect the berry from Norman in Petalburg City Gym.

Pokémon holding these berries were allowed to be Pal Parked into Generation IV, however their held item would become the Enigma Berry.
In Generation III, there is no legitimate way to acquire the Enigma Berry, as it is merely a placeholder in those games.

Additionally, the data for these e-Card Berries do not exist in the ROM data of the Gen III games;
the e-Card data is loaded into the save, and the game uses the placeholder Enigma Berry to display the stored data.
So in reality, the player is merely holding onto the Enigma Berry, but the player would not know, as the data shown belongs to the e-card Berry scanned.

These e-Card berries can be injected using @suloku's tool.

Description
This promo card was only available to Japan, and even then it was not easy to come across one.
There were a few different draws throughout the years in Japan, and it each time it was mailed to lucky winners,
who mailed-in proof that they purchased at least 6 e-reader booster packs during the promotional period.

This promo card does not store itself in some way on the save,
so it could not be extracted like e-Card Trainers and e-Card Berries (as .ect and .ecb respectively);
it basically ends up directly adding the doll to your save, not particularly different from the way this tool works.

Additionally, @HaxAras has a page that provides a bunch of saves, as well as detailing how to transfer the dolls onto an international system.

Usage
In order to use this .raw, users will need a VBA link with e-reader support.
Instructions on how to use the VBA link with e-reader support can be found here.

These e-Card trainers can be injected using @suloku's tool or @BlackShark's tool.

Out there in the wild, exists a German Language Debugger's/Developer's Edition of Pokemon Ruby Version,
which contains many debugging tools, including Mystery Event distribution subroutines.
Working on the data first documented by The Cutting Room Floor and GlitchCity Forums,
the E-card Trainer was finally extracted by @jojo12100 using @suloku's tool.

There are e-Reader cards that allow you to challenge trainers in the old man's house in Mossdeep City,
and the trainer can be swapped out by scanning a different card.

This card data contains a trainer that is a Pokemon Ranger, with his name being "Card E" (Japanese: カードいイー),
and rather peculiarly have the names of his Pokemon being in English ("TOURNAMENT").
Note: Japanese games are hard coded to only display up to 5 Characters for Trainer and Pokemon Names,
even if the Pokemon has a longer name, as seen in the comparison below.

It's possible that this e-Card was originally Japanese in a earlier revision of the debug rom,
which was likely based on a japanese debug rom, before it was adapted for localization.
The nicknames of the Pokemon was likely changed during localization.

[We will not distribute the Debug Ruby Rom, and it is against our rules to ask for it]

When the absolute difference between the player's Trainer ID and Secret ID is rather small (approximately less than 230)
and has a Pokemon with the Cute Charm ability (of a select gender) in the lead of the party (ie. a Cleffa),
shiny odds can be increased up to 21.34%, as long as the wild Pokemon species has a gender ratio that allows it to be male or female.
This particular abuse of the Cute Charm mechanic only works in Gen IV.
 
This page holds all the Shiny Pokemon I came across during my playthrough, that appear thanks to the Cute Charm abuse.
Each set that I upload will be unique (meaning a new set won't have stuff that I uploaded in a previous set)
Presently there's only three sets.
