UntieUnite

Reverse Engineering of Pokémon UNITE

Usage:

• Obtain a built version of the UntieUnite.ConsoleApp project's executable.
  • This .sln can be built with .NET Core 3.1 by using dotnet build untieunite.sln via command prompt.
• Create a .bat file next to the executable:
  • untieunite.consoleapp {dump}\assets\DlcRoot\0.3.0\DLC_0 {out_dir}
  • Replace {dump} with the folder that contains your download data from the app (having the above path).
  • Replace {out_dir} with the directory you want the dumps to be placed in.
• Run your .bat file, and the contents will be dumped for further analysis.

When the Console project is run the program will decrypt, decompress, and export as much content as possible.

Notes:

• Pokémon UNITE is a Unity 5x game developed by TiMi Studios (Tencent), with various reverse engineering deterrents.
• Game code has some obfuscations, similar to those done to League of Legends: Wild Rift (details about that game's obfuscation here)
• Bundles have some XOR encryption on the metadata to break the usual asset viewing programs.
• LanguageMap contains most of the localization text.
• Lua scripts are compiled (version 5.3).

Other Useful Programs:

• Il2CppInspector -- useful if you want to reverse engineer the game code.
• AssetStudio -- can open the dumped .bundle files to view & export assets.
