Disclaimer: While we deconstruct the Pokémon games, we do not endorse cheating which may be against Nintendo's terms of service, nor video game emulation of unauthorised video game copies, nor anything which violates technological protection measures (e.g. custom firmwares) which may be illegal. Hence readers are to make use of the information on this website at their own risk.

Welcome to the Glitch City Laboratories wiki! We are a Pokémon fansite dedicated to the various glitches and quirks of the game series.

We currently have 3,480+ pages, however we are still growing, and are in need of both new articles and further information on existing articles.

Want ideas for new content? Visit Glitch City Laboratories:Wiki tasks.


  • Major glitches — The most powerful glitches, such as those that allow you to obtain any Pokémon in the game.
  • Glitches by generation — A parent category of seven categories of Pokémon glitches by generation. Useful for looking up any particular glitch.
  • The Big HEX List — A reference table for index numbers and matching Pokémon, items, moves, characters and Game Boy ASM opcodes!
  • Reference documents — Pages not directly related to glitching, but containing info on topics such as other exploits, easter eggs, unused content, GameShark codes, in addition to how and why it all works.

More links can be found on the sidebar.


We appreciate all help for the wiki.

Before editing, we suggest that you should read our manual of style, learn what is expected of articles at GCL, and about our process for article validation.

If you are new to wiki editing, the MediaWiki help documents are a good place for information on how to edit wikis in general.


xx What do you think about organization here?

September 09, 2019, 01:08:34 pm by Sherkel
Thanks to sustained interest in the field from various parties over time, this wiki has never stopped growing. However, on a higher level, there's a consensus that the way the pages are organized is still on the wrong side of history, in addition to other site-wide elements. Is there too much of a mix of technical information, procedural outlines, and the cool results that all originally brought us here, without the three being clearly separated enough? Would new templates aid future edits? What about the current manual of style? Would a TVTropes-inspired system make the wealth of pages easier to navigate?

Collectively, we don't know, other than that we could do with something along those lines. Any visitor is free to suggest what that might be.

An excellent discussion was opened here on this subject. If you have anything to say or are curious what proposals have been made, come check it out!

xx Emulation of Crystal's Mobile Adapter

August 17, 2019, 04:37:31 pm by Sherkel
Of special interest to those interested in game preservation should be the REON Dev Team's successful trade conducted using an online protocol and a software implementation of the Mobile Adapter, most famous for its use in the Japan-only version of Crystal.

As their recent tweet (complete with video footage) reads:

"For the first time in 17 years and 8 months, a trade was done with Pocket Monsters Crystal using the GTS precursor at the PCC. A shiny Gyarados was traded for a Meganium."

Additionally, hardware that would allow for online trades to be conducted in this manner is in progress. On their Discord, you can find other material such as scans and screenshots, and even talk of "DLC content" that was distributed long ago for use with the phone adapter.

Worth reading too if you're interested in the details on what made this possible is Háčky's super in-depth research on how the adapter communicates with the GBC.

xx Speedrun routes on the wiki

March 25, 2019, 10:53:42 pm by Sherkel
As part of the recent restructuring we've been trying to give the site to keep it up-to-date, speedrun routes are now receiving articles. To get an idea of what advances in glitch research this series of efforts engendered, or of the depth that goes into routing, the two already completed already provide plenty of essential reading. Staying true to the site's purpose, the goal of these pages is to document in depth what's actually going on when you do those seemingly inexplicable series of inputs. Luckily, after I cluelessly dismissed the idea, our new contributor Bbbbbbbbba (with ties to pret!) went ahead and did it anyway. Speaking of which, many Generation I pages have been receiving long-overdue overhauls thanks to the aforementioned user and Luckytyphlosion.

In addition, there have been some recent updates to the German GlitchDex and Korean TMHMDex. Did you know that 기술머신49 can execute arbitrary code? Or that a counterpart to the household name 4 4 Hy exists in the German version of Yellow and learns Hyper Fang at level 205? Now you do.

xx Void Matrix

February 26, 2019, 03:38:03 pm by Sherkel
Anyone interested in voiding and Generation IV glitches in general has probably noticed RETIRE's YouTube channel by now, but in case you haven't, it is absolutely worth checking out! Advances in exploiting the fourth generation's maps and scripts have been happening as fast as when arbitrary code execution was discovered in the first generation, and similarly accessible arbitrary code execution in this generation is a possibility on the horizon, too. Within the past six months alone, "Never tweak again", "Shaymin in 5 minutes", "Credit warp", and "Catch Arceus infinitely" have appeared in video titles. Look for yourself if you don't believe it!

Interested, but prefer real-time updates and the directness of a chat? No problem there, as there is a Discord channel dedicated solely to these, already rivaling ours in amount of activity.
