The current [[
The run also uses many [[luck manipulation]]s. Most of them are to encounter specific Pokémon in their intended habitat, either by [[Luck manipulation (Generation I)#DSum manipulation|DSum manipulation]] or by [[Luck manipulation (Generation I)#Hard-reset RNG manipulations|hard-reset manipulations]] (including a Pidgey at the beginning for [[Brock Through Walls]]). Two other manipulations are used near the beginning, to get a desired Trainer ID and to death-warp from a trainer twice for a x255 item stack.
Line 66:
** If the player died to the first MissingNo., repeat the Spearow manipulation above. If the player escaped, the leftmost trainer will not be usable, so [https://www.youtube.com/watch?v=HTG2Wu6euGU do a manipulation with another trainer] instead.
** Since the "13 ERROR." glitch text box points to the Route 11 trainer defeat flags, escaping from the first MissingNo. will set the first byte to 0x08 (TX_ASM), leading to a crash. '''Therefore, in this case the player should flash the Start menu instead of reading the Vermilion Harbor sign.''' (The guide states that reading the Harbor sign crashes even if the player died, but this is unconfirmed either way.)
** Don't bother running away this time. Since we want to be at the Pokémon Center anyway, selecting a weak attack and (hopefully)

* Although X = 39 is out of bounds, the player does not really go [[out of bounds]], because the map view pointer is not updated. Instead, the player has a "out-of-bound experience" where all NPCs and warps disappear (because they are shifted out of the screen), but the background tiles, including their collision properties, work as normal.

* Note: "Map music ID" is only used when starting the music (e.g. after getting off the bike); "valid map connections" and "north connection preview data source" are only used when first loading the map.
* Walk up one step.
** Because the player is now at Y = 0, stepping up triggers the north map connection, sending the player to the Power Plant. Since the tileset has changed, the game thinks the player has taken a warp, and places the player at the entrance of the Power Plant.
