README
Pokémon Legends: Arceus Recomp


An independent amateur project focused on the recompilation of Pokémon Legends: Arceus.
This project is a personal learning experience, developed with the knowledge, time, and resources available to me. I'm doing my best to make it work, improve it, and share my progress with the community.
I'm not a professional developer, and this is not an official, finished, or commercial product. Bugs, limitations, compatibility issues, and incomplete features are to be expected.

Setting Up the Game Files
To recompile and run this project, you must provide the extracted files from your own legal copy of Pokémon Legends: Arceus.
Original game files are not included or distributed with this project.
1. Extract the Game Files
You will need the ExeFS and RomFS contents extracted from your own copy of the game.
2. Place the Files in the Correct Folders
Inside the main project directory, locate the extracted folder.
Place the extracted files in the following structure:
Pokemon Arceus Recompzada/
└── extracted/
├── exefs/
│ ├── main
│ ├── sdk
│ ├── subsdk0
│ ├── subsdk1
│ └── other required ExeFS files
│
└── romfs/
├── bin/
├── system_resource/
└── other extracted game files
Important: Place the contents of ExeFS and RomFS inside their respective folders. Do not place the compressed archives or the parent folder containing both directories there.
3. Recompile the Game
After setting up the files:
- Run
recompilar_arceus.batorlasrecomp.exe. - Wait for the code generation and compilation process to finish.
- Once compilation is complete, run
executar_arceus.bator openlasrecomp.exe.
The first compilation may take some time, depending on your computer's hardware.
