An internal function in the code for wiping the save file known unofficially as "ClearWRAM" does not function correctly.<ref>[https://github.com/pret/pokecrystal/blob/master/docs/bugs_and_glitches.md#clearwram-only-clears-wram-bank-1 List of glitches relevant to the engine]</ref> It may be worth noting, there are more specific glitches in the game, such as "Hall of Fame SRAM glitch" (box 2+ data becomes invalid, and allows the player to ultimately obtain [[glitch Pokémon]] and [[?????]] without bad cloning, if the player clears the save file and enters the Hall of Fame without saving in between). This glitch is loosely similar to Generation I SRAM glitches related to impartial clearing, such as the "ghost Bicycle" phenomenon, "save abuse" and string names leftover from the previous save file with [[- (move)]]. Another SRAM glitch is the Japanese Poké Communications Center SRAM glitch (mentioned at [[:#Pokémon Communication Center|the header Pokémon Communication Center]], though that one is related to exhausted or broken save batteries).

====Shiny Ditto DV manipulation====
In Generation I, if a {{OBP|Pokémon|species}} uses the [[move]] {{m|Transform}} while already transformed, it will retain the {{IV|DV}}s of the Pokémon it transformed into after being {{pkmn2|caught}}. Due to {{Shiny|Shininess}} being determined by DVs in Generation II, this allows the player to make a {{pkmn2|wild}} Ditto Shiny by having it use Transform while already transformed; accomplishing this is possible by either having a Shiny Pokémon that knows Transform ({{p|Mew}}, certain [[glitch Pokémon]], or another Ditto) or by teaching a Shiny Pokémon the move {{m|Mimic}}, then having the wild Ditto use Mimic on the move Transform. The end result is that the Ditto will be Shiny in the Generation II game.

The [[Time Capsule exploit]] works around the programming checks put in place on the [[Time Capsule]] to prevent players from trading [[Generation II]] Pokémon to [[Generation I]] games.

====Shiny Ditto DV manipulation====
In Generations I and II, if a [[wild Pokémon]] uses the [[move]] {{m|Transform}} while already transformed, it will retain the {{IV|DV}}s of the penultimate Pokémon it transformed into. Due to {{Shiny|Shininess}} being determined by DVs in Generation II, if a non-Shiny wild Pokémon transforms into a Shiny Pokémon and then uses Transform again, it will become a Shiny Pokémon. Conversely, if a Shiny wild Pokémon transforms into a non-Shiny Pokémon and then uses Transform again, it will become a non-Shiny Pokémon. This way, a wild Pokémon can even switch between Shiny and non-Shiny versions multiple times in the same battle. This does not work on a Pokémon owned by {{pkmn|Trainer}} (either the [[player character|player]] or a [[non-player character]]).
This allows the player to make a {{pkmn2|wild}} Ditto Shiny by having it use Transform while already transformed; accomplishing this is possible by either having a Shiny Pokémon that knows Transform ({{p|Mew}}, certain [[glitch Pokémon]], or another Ditto) or by teaching a Shiny Pokémon the move {{m|Mimic}}, then having the wild Ditto use Mimic on the move Transform.
In Generation II games, after the wild Pokémon transformed twice in the current battle, it still appears with its original color palette at first. However, once the player opens the [[party|list of Pokémon]] or the [[Bag|Pack]] and then returns to battle, the color palette will be updated. At this point, a non-Shiny (purple) Ditto would appear with its Shiny (blue) color palette.
It's not possible to catch a Shiny version of any other Pokémon species using this method, due to the additional glitch which causes any transformed wild Pokémon to be a Ditto when caught.
Some Pokémon guides incorrectly state that this glitch requires catching the wild Ditto specifically in a Generation I game, and suggest trading a Shiny Pokémon from Generation II to Generation I to accomplish this. However, it actually can simply be done in a Generation II game, without any trades.
