Brock through walls: Difference between revisions

'''Brock Through Walls''' (path manipulation walk through walls) is a [[walk through walls]] glitch in {{RGBY}}, popular in speedrunning.

The "walk through walls" [[GameShark]] code has always been fun and useful to people. Contrary to popular belief, a similar effect is possible without the use of a [[game-altering device]] via a glitch. It is possible to perform the "Brock Through Walls" glitch very early in the games (except in {{Y}} because the Youngster cannot be skipped in this version).

As it shouldn't be possible to talk to the Youngster from the right, the developers never programmed a path for the Youngster to follow when the player is right of the Youngster. When talking to him, the game looks for the player's coordinates but often never finds them, resulting in a softlock.

However, the player is able to write some pseudo-data in RAM representing the player's coordinates (which in this case should be $10 $24), which leads the game into using the next two bytes as a path pointer provided that the coordinates appear at an address at xxx2, xxx6, xxxA, or xxxE.

Particular paths may overwrite the 'disallowed buttons' variable, allowing the player to walk through walls, similar to what happens in the glitch [[walk through walls trick (museum guy method)]].

The player must have performed a method of the [[Pewter Gym skip glitch]], or have otherwise skipped Pewter Gym through another means such as a wrong warp by manipulating item 36's quantity (exit destination) in the [[expanded items pack]].

The latter is possible if an item quantity is manipulated to 255 (e.g. by using Missingno. to duplicate it by 128 first, reducing the quantity to 127 and duplicating it to 255). Two methods to do this without defeating Brock include the [[Cable Club escape glitch]] with [[Missingno.]] or after trading a Pokémon with [[- (move)|"-" as the first move]] from Red/Blue to Yellow (as CoolTrainer corruption can freeze the game outside of particular places such as Diglett's Cave in Red/Blue but not Yellow). With "-" corruption, it is possible to corrupt the enemy Pokémon into a Missingno. by opening the Pokémon menu before opening and closing the Fight menu/scrolling past "-".

* It must be level 8.

* It must be the '''last''' Pokémon in your party.

** The second attack's PP must be exactly 16.

** The third attack's PP must be exactly 36.

Once the player stands on tile right from the Youngster and performed to correct action (listed in the corresponding Requirement sub-section):
