Pokésav or Pokesav is an unofficial series of popular save file editors and Action Replay code generators for all Generation IV core series games and Pokémon Black and White.It originated as a Japanese program hosted on the website pokesav.umimi(.com), but Pokésav programs have been translated/modified for other languages.

Location names problem
Both Japanese (apparently does not apply to later versions) and English versions of Pokésav for Pokémon HeartGold and SoulSilver do not have Kanto and Johto locations in their location drop down boxes, making it harder to produce 'legal' looking Pokémon with Pokésav.If the index number of the Kanto or Johto location is known, then the player can enter the decimal index number on Pokésav. Though Pokésav may call the location "----------", it will appear as the actual location on the HeartGold/SoulSilver game.
Anti-virus problem
Pokésav may be blocked by a computer's anti-virus software as malicious (e.g. as a 'trojan horse' by AVG). This means that you may have to add a Pokésav program as an exception that will not be blocked, or temporarily disable the anti-virus software.Additionally, the browser Google Chrome may flag Pokésav as malicious and prevent you from downloading it.
Legality and legitimacy of Pokesav generated Pokémon
It is possible to generate a Pokémon with qualities of a 'legal' Pokémon in Pokésav, but the player can also successfully produce a Pokémon that is clearly 'illegal', such as a Spiritomb with Wonder Guard.Additionally there are hidden hex values in a Pokémon's structure (named 41h-47h, 5Eh, 63h-67h and 85h-86h) that give information about a Pokémon's origin. People who hack in Pokémon with Pokésav are likely to ignore these values, meaning that the Pokémon is illegal, even if it looks legitimate in game.
