Ten question marks/Obtaining ??????????/Pre-starter method

Another method for obtaining ?????????? is to use an Action Replay code to teleport or walk through walls to an area where a wild Pokémon can be captured before getting a starter Pokémon from either Professor Birch in or Professor Oak in. If a wild Pokémon battle is initiated, the player will send out a ?????????? with 0/0 HP and with a hexadecimal identifier of 0. If the Pokémon gets hit, the player will white-out and be sent to a Pokémon Center where 65536 Poké Balls will begin to appear in seemingly random locations in a horizontal line across the screen (this is because the game will refer to the number 0 as one more than a full two bytes (65535)). A very similar effect occurs when one performs a variation of the Pomeg glitch; when the Pokémon's HP goes below 0 it will skip to the largest value. This system uses two bytes, so the Pokémon's HP will start to drop down from 65535.

After this Pokémon is captured, if one chooses to nickname ?????????? or looks at it in the party screen, its sprite may appear as a gold-colored. This is due to using icon palette 0 replacing an undefined palette. Another way to see this glitch is to use the "walk through walls" code, go to the Link Cable area, and battle. Since there is no connected opponent, this glitch appears instead (as value 000).
