List of tools:

• Catalog -> Decrypts all the dbs from AppData\LocalRow
• MetadataDumper -> Dumps decrypted metadata from process memory
• Protobuf -> A tool to recover protobuf definitions from the game assemblies, together with their HTTP paths
• StaticData -> Fetches AND decrypts the latest StaticData.zip (game data) from live servers
• UnLuac -> Decompiles Lua bytecode back to original code, modified for Nikke lua

How to use them?

• Catalog | StaticData -> Just compile and run, works straight out of the box
• MetadataDumper -> Compile the project via Visual Studio 2022. Take theput the NikkeMetadataDumper.dll from Win64 generated folder, together with the files in Gadget folder, and put them all in game directory next to nikke.exe. Run the game, a decrypted global-metadata.dat will be generated in the game directory.
• Protobuf -> Compile the project via Visual Studio 2022. Use the generated global-metadata.dat to dump Il2Cpp via Il2CppDumper. Then either put the DummyDll folder next to the NikkeProtoDumper.exe, or drag the DummyDll folder into the NikkeProtoDumper.exe. Nikke.proto will be generated, in proto3 format.
• UnLuac -> Run compile.bat to compile the project. Then put all the .lua.bytes files you got from YarikStudio or AssetStudio into the Lua folder. Run the DecompileAll.py python script, and all the decompiled luas will be generated in Decompiled folder.
