Back in the day there was a strange post in the glitchcity forum, claiming that a unobtainable Shadow Loudred briefly appears during the purification demo.
It took us a year but we finally got in our hands. Other shadow entries (presumably from the same Purification Demo) has also been included.
In Pokémon Red & Blue, a strange glitch was discovered by the GlitchCity old forums. (Less loud and more readable version here)
According to the report, it appears that after performing a variant of having the Safari Step counter time out when the boy in Pewter City take the first steps to bring you the the museum, talking to the boy again afterwards will result in a "hooked" Dragonite appearing, before freezing your game.
Jojo12100 was able to dump its info and replicate it, much like the process done for the Gen 1 Ghost Marowak.
Do note that in the data, it's level is 0. (PKHeX views any species with 0 EXP as Lv 1)
Besides Dragonite, other possible "hooked" encounters includes Metapod and Missingno. Those encounter are triggered by different conditions.
This page has an explanation of how Hooked Pokémon glitches work.
In June 2019, a Japanese copy of a Debugging variant of Pokémon Diamond Version was found and subsequently dumped.
When pressing down Select on the start screen, a debug menu appears. If the player opts to proceed with the debug start, instead of the standard way to start a fresh game,
the player will end up having 3 Pokémon in their party, namely: Infernape, Piplup and Finneon, all at Level 99.
It appears that it may be possible to shiny hunt these entries.
Special thanks to the @TheShadyRelapse for the speedy retrieval of these Pokémon.
As usual, these files would be illegal and should not be transferred. Use at your own risk.
[We will not distribute the Debug ROM, and it is against our rules to ask for it]
Like Pokemon Red/Blue and Stadium 1/2/3, Pokemon Colosseum and XD have debug trainers used to test many things like New Forms of Deoxys in XD or Pokeballs in Colosseum.
Pokemon they used are well ... totally WTF but that's just for debug
These files are the 2 starters you got from XD Demo, the 3 shadow pokemon you snatch and a random Zubat from the first trainer.
Not that you can shinyhunt the starters (ID/SID/IV random but Nature fixed).
The demo can be found on the Multiboot Demo Disc of October 2005.
Like XD Colosseum had a demo which you can find in May 2004 demo disc, unlike it there is nothing really interesting to get, but hey that's always a demo we can get in hand ...
The files contain the 2 starters (Umbreon/Espeon) and 2 trainers Pokemon.
Thanks @BlackShark for dumping them.
Thanks to GlitchCity researches we discovered in Gold/Silver an unused map called DA00 in Kanto that generates wild Pokemon.
Chances of corrupting your save with it are very high and Pokemon are over lv100.
Apparently another like that exist also in Crystal but it was not documented.
Discovered in Gold/Silver ROM Entei had an unused Script meaning it was planned to have a static encounter probably in Burned Tower, this idea was scrapped but used in Pokemon Crystal with Suicune this time.
