- Generation III to Generation IV
- Unlike Generation II's Time Capsule, the transfer from Generation III to Generation IV via Pal Park is permanent; Pokemon sent over cannot be returned to any Generation III game.
- First, Pokemon must be migrated from the Generation III game.
- If a Generation III Game Pak is inserted in the GBA slot of the same Nintendo DS or Nintendo DS Lite system as the Generation IV game and the player has visited Pal Park, an option will appear on the main menu labelled "IMPORT FROM ".
- When selecting this option, the player is presenting with a stripped-down view of the Generation III's game's PC on the Nintendo DS's touch screen (the player cannot view the Pokemon's statuses, other than their minisprite, species, nickname, level, markings, and held item).
- Pokemon that know a move that is an HM in either the origin or the destination game (called "hidden moves" by the game) cannot be migrated.
- After selecting exactly 6 Pokemon, the game will confirm with the player that they want to send those 6 Pokemon.
- If the player has any migrated Pokemon that have not yet been caught, no additional Pokemon can be migrated.
- In Diamond, Pearl, and Platinum, it is only possible to migrate 6 Pokemon to that game from a specific Generation III game once per 24 hour period (excluding manipulations); in HeartGold and SoulSilver, this restriction was lifted, allowing an unlimited number of migrations from a single game in a 24 hour period.
- Pokemon can only be migrated if the Generation III game and Generation IV game are the same language, unless the Generation IV game is Korean, in which case any language Generation III game can be used (due to the Generation III games not being released in Korean).
- However, it is possible to trade between languages in Generation III, so it is possible to migrate, for example, a Pokemon originally met in a Japanese game from a Spanish Generation III game to a Spanish Generation IV game.
- It is worth noting that the games will permanently set a nickname flag if a Pokemon's name does not match the expected name for that language.
- As a result, using Pal Park in Korean will always trigger the aforementioned flag, since the GBA versions do not even have the expected charset in them.
- Despite the game having settings in place to restrict the amount of Pokemon migrated in a single day, these restrictions can be avoided and an unlimited number of Pokemon transferred into Generation IV.
- If, once a Catching Show has been completed, the player turns off the game system and changes the date on the Nintendo DS to show one day later, and inserts a second Generation III game, he or she will be instructed to reset the time on the DS.
- This will prevent migration from the second game, but allow the original game?that has already had six Pokemon transferred?to send Pokemon into the Generation IV game.
- Also, the Nintendo DS's clock can be set to the time displayed in the GBA cartridge before choosing Pal Park option to avoid the 24 hour period of waiting before transferring their Pokemon.
- Despite these workarounds, no further migrations can be made until all six Pokemon transferred have been caught, and changing the Nintendo DS clock or playing the game on another Nintendo DS system will delay Pal Park migration for 24 hours.
- In addition to transferring Pokemon from Generation III, Pal Park also has a score system that will offer rewards depending on the player's score.
- The score will be given at the end of the Catching Show by the Park Ranger.
- The score is worked out by how fast the captures are completed and what Pokemon are transferred over.
- If a rarer or a legendary Pokemon is migrated, such as Mewtwo, a higher score will be given, as opposed to more common Pokemon such as Rattata, which will be given a lower score.
- Timing will also alter the score: if it takes longer to complete the challenge the score will be decreased; however, if it takes a shorter amount of time to complete the challenge, the score will be increased.
- When Pal Park is first visited, a default high score of 2000 will be set by the player's rival (either Barry in the Sinnoh games or Silver in the Johto games).
- The Park Ranger always gives the player a Berry as a reward; the higher the score, the rarer the Berry.
Modifications to transported Pokemon
- Despite the player in the Generation IV game catching the Pokemon again, its OT, ID number, and Poke Ball remain the same.
- Its friendship is reset to 70.
- Many Pokemon obtained in Generation III gained an Ability in Generation IV.
- Due to Ability being dependent on personality value in the Generation III and IV games, this means that some migrated Pokemon have an Ability that does not match their personality value (since the Ability is not changed upon migration).
- However, because Abilities are recalculated upon evolution in Generation IV and V, if that Pokemon evolves in games of these generations its Ability will change to match its personality value.
- While non-English and non-Japanese characters cannot normally be used in the Generation III games, they do occur in some in-game trades and preset player names.
- If a Pokemon has a nickname or original Trainer that has one of these characters, it will be turned into a kana character in the Western Generation IV games due to encoding issues.
- Pal Park only reads the data of the game the Pokemon was originally generated in, rather than its in-game met location.
- This sets any Pokemon created in FireRed or LeafGreen to Kanto; Ruby, Sapphire, or Emerald to Hoenn (even if it was caught on Navel Rock or Birth Island, which are located in Kanto); and Colosseum or XD to "distant land".
- (Pokemon obtained from Wonder Cards are treated as being created in the game they were received in.) A Pokemon whose Egg is created in a game based in one region and traded to another region before it was hatched will display the name of the region it was generated in, rather than the one it was hatched in; this means that a Pokemon generated in Emerald but hatched in FireRed will have the OT and ID of the FireRed player but list that it was met in Hoenn.
- In addition, the level obtained at is changed to the level arrived at.
- Due to the lack of a met date in the Generation III games, the date obtained becomes the date it was caught in the Catching Show.
