## 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](https://github.com/J-D-K/JKSV/releases).
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.

## Usage
This paragraph refers to the Windows Form app. The Command Line app usage is similar and should be fairly intuitive.
* Ensure you have the required [.NET 8.0 Desktop Runtime](https://dotnet.microsoft.com/en-us/download/dotnet/8.0) correctly installed
* Dump your game's BCAT with [JKSV](https://github.com/J-D-K/JKSV/releases) and keep some copies somewhere safe
* Open the 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 duplicated WCs and click `Apply`
* Click the `Save as BCAT Package` button and browse to your dumped BCAT
* A folder called "Forged_BCAT_{Game}" should appear next to your dumped BCAT
* 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)

* Ensure you have the required [.NET 9.0 Desktop Runtime](https://dotnet.microsoft.com/it-it/download/dotnet/9.0) installed correctly.
* Dump your game's BCAT with [JKSV](https://github.com/J-D-K/JKSV/releases) and keep some copies in a safe place.
* Open the tool and select your game of choice.
* Import the wondercard files of your choice (by drag & drop or by clicking the `Open Files` button).
* Optionally, edit the wondercard ID (WCID) if you have duplicate WCs, then click `Apply`.
* Click the `Save as BCAT Package` button and browse to your dumped BCAT.
* A folder called "Forged_BCAT_{Game}" should appear next to your dumped BCAT.
* Restore the forged BCAT using JKSV.
* To redeem the old event gifts, 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). 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 my [bcat_updates](https://github.com/Manu098vm/bcat_updates) repo or from [citrusbolt](https://github.com/citrusbolt)'s [website](http://citrusbolt.net/bcat/) and add the missing files to your dumped BCAT, then restore it with JKSV.

* All the Switch Gift Data Manager projects require .NET 8.0.
* .WinForm is a Windows Form application and can only be built in Windows Operating Systems.
* .Core and .CommandLine can be built in any platform OS.
* Use the Debug build configuration when editing or developing code related to the .WinForm project. Build as Release only once the code is finished.
* To build the projects, open the .sln file in the root directory with an IDE such as Visual Studio 2022, click `Build` -> `Build Solution`.

The .CommandLine project is currently just a simple script that calls the .Core functionalities and can run on any popular OS. Feel free to improve it and/or submit a pull request if you'd like :-)
