Brock through walls: Difference between revisions

In order to execute Brock Through Walls, the invalid path needs to be long enough to overwrite at least the entire RAM region between $CCD3 and $CD3B. Most addresses in this region are temporary variables anyway; however, this region includes $CD2D (wEngagedTrainerClass) and $CD2E (wEngagedTrainerSet), which determines the species and level of the Pokémon encountered with the [[trainer escape glitch]] (normally the special stat and attack modifier of the last enemy Pokémon). Therefore, by doing a trainer escape, and performing this glitch before going back to the route, the player can set up a "special stat encounter" without needing to fight a Pokémon with the appropriate special stat and attack modifier. Notably, this allows encountering a Pokémon whose level is not in the 1~13 range (the valid range for the attack modifier byte).
