GitHub Source Code Download Latest Release About This tool aims to make past Mystery Gift event contents back again in all the Pokémon games for Nintendo Switch. Since those games won't allow event injection in the SAV file, this tool creates a forged BCAT package, injectable with homebrews like JKSV. This allows wondercards to be redeemed through the In-Game Mystery Gift Menu. The use of this tool does not involve hacking the game ROM nor hacking the game SAV. Video example: Compatible files Let's Go Pikachu and Let's Go Eevee wondercard full files (.wb7full) Sword and Shield wondercard files (.wc8) Brilliant Diamond and Shining Pearl wondercard files (.wb8) Legends Arceus wondercard files (.wa8) Scarlet & Violet wondercard files (.wc9) BCAT wondercard files, either with mutiple or single wondercards (no file format extension) Compatible games Pokémon Let's Go Pikachu and Eevee Pokémon Sword and Shield Pokémon Brilliant Diamond and Shining Pearl Pokémon Legends Arceus Pokémon Scarlet and Violet Disclosure Neither I nor the Project Pokémon staff takes any responsibility for possible adverse outcomes or bans due to the use of this tool. Use at your own discretion. N.B: Some BCAT files contain sensible console-specific informations, which you should keep safe. Don't share your BCAT to others! Usage Tutorial The following tutorial refers to the GUI version of the program. The .CommandLine app is currently just a simple script that calls the .Core functions and can run on any popular OS. Its usage is similar to the Windows Form app and should be fairly intuitive. Ensure you have the required .NET Desktop Runtime 8.0.x correctly installed Download the latest tool release from GitHub Dump your game's BCAT with JKSV and keep some copies somewhere safe Open the Switch Gift Data Manager tool and select your game of choice Import wondercard files of your choice (by drag & drop or by clicking the `Open Files` button) Eventually edit the wondercard id (WCID) if you have invalid WCs and click `Apply` Click the `Save as BCAT Package` button and select your dumped BCAT folder in the "Source BCAT Path" section. The path must lead to the folder containing the files "directories.meta", "etag.bin", "list.msgpack", "na_required", "passphrase.bin" [N.B: if your dumped BCAT only has the "passphrase.bin" file, it means it was not initialized properly. Connect in-game and use any Mystery Gift feature at least once to initialize the BCAT. Downloading Wild Area News or Poké Portal News works too] Click the "Save" button A folder called "Forged_BCAT_{Game}" should appear next to your dumped BCAT (or in whatever path you selected in "Destination BCAT Path") Restore the forged BCAT with JKSV To redeem the old fashion events, open your game -> Menu -> Mystery Gift -> redeem via Internet When you're done, restore your original BCAT package with JKSV (not doing so may cause sync issues) N.B: BCAT Sync usually occurs between 12:00 AM (UTC) and 01:00 AM (UTC) if there is new BCAT content in the servers. I suggest to not follow this procedure during that timeframe to avoid a desync. If you experience a desync, follow one of these methods to resync: Open JKSV, select BCAT, hover over your game and press X to open the menu, then click `Reset Save Data`. Download the latest BCAT for your game from citrusbolt's website and add the missing files to your dumped BCAT, then restore it with JKSV.

Hey all, Been using PKHex for a minute, PokeGen before it, yada yada yada. However, I haven't used it since maybe gen 5 and I'm having a bit of trouble. I have my original Diamond save, extracted from the cart, loaded in PKHeX. With it, I can extract the specific handful of Pokemon I want to move over. It saves them as .pk4 files. When I use PKHeX to load up BDSP save, and then try to open to .pk4 files, it naturally gives me the error: "Attempted to load an unsupported file type/size. This could be caused by loading a different generation Pokemon file on an unsupported generation or your file is corrupt." Which is true. It is - I guess through the sheer power of technicality - a different generation. How can I bring my gen 4 Pokemon from the original Diamond into my current Brilliant Diamond save? P.S. I do have multiple hacked DSes and 3DSes and a single hacked Switch and a single unhackked one, so I understand my options are limitless unless there's simply no non-Nintendo-official way. As I understand it now, one option I have is trading them from Diamond to Black, from Black into Pokemon Bank, from Bank into Home, and from Home into Sword or Shield, export that save, export the Pokemon, then import them into BDSP. But I do not want to do all of that. I feel like there (hopefully) is an easier way. Thanks!
