Line 1: The current [[~~bp:~~Pokémon Red and Blue ~~Versions~~\|Pokémon Blue]] any% No Save Corruption speedrun route is based on [[glitch meta-map script activation]] after the "death-warp" variety of the [[trainer escape glitch]]. It warps to the credits by [[arbitrary code execution]], which has a chance to fail because the execution flow goes through the in-game timer. Since the arbitrary code execution begins at address $F8FF, this method is also known as "[[Viridian Forest 0xF8FF glitch]]". Two [[luck manipulation]]s are important for the glitched portion, one to get a specific value of the Trainer ID for the glitch setup, and another to get an encounter on the exact tile in front of a trainer to trigger the death-warp. A third luck manipulation is used to get a Spearow with specific DVs to win or lose the battles faster. Line 11: * If there is an existing save file, clear it by pressing Up + Select + B on the title screen. * [https://youtu.be/u5_hDQ7H98w '''Manipulate for a Trainer ID of 0xF1C8 (61896).'''] * '''Name the player character "m<{{MN>}}a.♀tF".''' * Choose the starter and name it to suit the needs of the Spearow manipulation later. (Charmander and Bulbasaur ~~has~~have different advantages for speedrunning.) * Finish the rival fight, deliver Oak's Parcel, and get Poké Balls. * Manipulate for a Spearow with low Special DV and high DVs in everything else.
