This is a collection of all possible Trades and Gifts of in-game NPC's credentials in every language possible.
All Generation I-IV Trades are obtained at the lowest level possible with thorough research.
Please refer to the Guide.txt included in the collection archive for details on what to edit to make any of them to your personal liking.
NOTE: If you're reading this in the future and a new game came out, please do not expect any updates with its trades immediately or anytime soon, unless users contribute them to me.
@Taargüs Taargüs - For providing the PK5s for all languages of B2W2 Yancy and Curtis trades, and also the Korean B2 Petilil!
@RobustRabbit - For providing CHT SM and USUM trades!
@ViolentDarkBrown - For providing all languages of trades in Let's Go, Pikachu/Eevee, Sword/Shield, and Brilliant Diamond/Shining Pearl!
Serebii and Bulbapedia - For providing the location whereabouts and details for the lowest levels possible of NPC's requested Pokemon. (Even though they contradict each other sometimes...)
And of course, anyone who reports errors!
If you would like to share this collection archive around other websites, you are free to do so, but please give credit to the mentioned users for their generosity to contributing. Thanks!
PSA: If PKHeX flags any Pokemon as invalid, please do collate the files that do so and report them in the PKHeX forum. And if you think a Gen 1-4 Pokemon can't be at a certain level, please do notify me about it (and provide sources).
