Exploring the Mew Glitch

In this video we explore the long range trainer glitch, or, as it's more widely known, the Mew glitch! This glitch allows us to catch mew on the original Pokemon Generation 1 games for the Game Boy.

Fyi, this is not the quickest way to catch mew - the trainer to the west of the nugget bridge can be access much earlier in the game and is the easiest & quickest way! I used this specific trainer because it was (as far as I can tell) the "first" version of this glitch that was discovered :)

To clarify the engaged trainer class, as there were some comments about it: During the fight against Youngster, the byte "engaged trainer class" is used as the second byte of Slowpokes special stat. It's a 16 bit value, so at 7:55 you can see that it's 0x0015. As we go back to route 8, DisplayEnemyTrainerTextAndStartBattle however uses this value as "engaged trainer class". So the second byte of the special stat of Slowpoke sets what Pokemon/Trainer we will see when we go back to i.e. route 8. If it's over 200, it will engage a trainer, if it's under 200, it will engage a Pokemon. And the Pokemon we are encountering is the one with the ID in "Engaged Trainer Class" at that moment - Mew.
