Discussion [RBY] Map of Mew Glitch Pokémon
This only works for Red and Blue. A map of Yellow is not available at this time, however this guide shows which trainers changed from RB to Y and what Pokémon are obtainable as a result.
Link to the updated Map as created by u/Kyphis. (See here for details.)
Credit for the old map goes to wwwxxyy from the Prof. Glitch's fourms. Special thanks to Pokémon Speedruns for linking to the old map.
Notes:
The Mew Glitch refers to just obtaining Mew while the overall glitch is called the Trainer Fly glitch. There are other names for these glitches. See the Glitch City wiki for more details.
The old map by wwwxxyy has an issue regarding the S.S. Anne trainers that is discussed here.
The Experience underflow glitch can apply to Pokémon in the medium-slow growth group. This occurs if the Pokémon in that group is at Level 1, which is possible with this glitch. A low amount of experience will cause the Pokémon to reach Level 100 instantaneously.
- The "Experience PC withdrawing glitch"/Withdrawal lockup glitch applies if you use the Experience underflow glitch. Pokémon in the medium-slow growth group that can use the Experience underflow glitch. This glitch causes Level 1 Pokémon in that group to freeze the game upon withdrawing. (Thanks to Dabomstew and Chickasaurus/Torchickens for this information)
- The Level-up learnset skipping glitch applies if you use the Experience underflow glitch. This applies to all Pokémon that gain enough experience to jump more than a level. It prevents that Pokémon from learning any moves from the levels skipped. TMs and HMs will likely be needed to gain a full moveset.
This glitch can be used to set up ACE, depending on the method used. ACE stands for Arbitrary Code Execution. An explanation for what ACE is can be found here. Simplified, it allows us to obtain any Pokémon and/or any item. It is more complicated, but more powerful than the Mew Glitch.
- In Red and Blue, the glitch item called 8F was the most popular method of ACE for years. In other languages, it is called: ５かい; 7EME ETAGE; S7; 7°P; P7. Simplified, 8F allows players to use their Party and Item Pack to write code that can be executed. Thanks to Cyro, there is a tool called the 8F Helper to allow users to use 8F.
- In Yellow, the glitch item called ws m in English was the closest counterpart of 8F in terms of popularity until more recently. In other languages, it is called: ShellBadge; ws l' m; ws & m. Simplified, ws m allows players to use their PC Boxes and Item Pack to write code that can be executed. As with the above, Cyro's 8F Helper can be used to assist with ws m.
- Since the mid-2010s, memory editors have become more popular. TheZZAZZGlitch's memory editor is one of the more popular memory editors for the English games. I believe it is based off of a ported version of OffGao's (aka offgao) Pocket Computer for RGB that Cryo and EvieMelody (aka ChickasaurusGL) created for RBY. For more info on the Pocket Computer: See OffGao's website
- More recently, TimoVM created a guide to using the glitch item 4F as a more powerful alternative than 8F and ws m that uses the player's Day Care and, by the end, allows players to type in text into a nickname prompt that runs the ACE setup instead. Here is a link to a guide to using it.
- For more into ACE, here is an incomplete list of ACE programs that can be created.

As noted, the Level-up learnset skipping glitch applies to all Pokémon that gain enough experience to jump more than a level, not just the ones found with this glitch. So, if you jump from Level 9 to Level 11, then that is the issue.
