Mod tool for Castlevania: Symphony of the Night

SotN Editor

SotN Editor is a mod tool for Castlevania: Symphony of the Night.

It is currently only capable of parsing and displaying data contained within map files (ST/*/*.BIN and BOSS/*/*.BIN), but it will eventually be able to modify map data (entities, tiles, rooms, etc.) and export those changes back into a working ROM file.

Platform	Status	Download
Windows		Windows 64-bit (x86)
Linux		Linux 64-bit (x86)
macOS		macOS

Usage

When loading for the first time, SotN Editor will ask for the locations of the PSX binary (SLUS000.67), the SotN binary (DRA.BIN), and the common graphics file (BIN/F_GAME.BIN).

To load a map file, click on File -> Open Map File, then select one of the map files in the ST/ or BOSS/ directory (e.g. ST/ARE/ARE.BIN).

Once the map is loaded, the map can be navigated by either clicking and dragging or by using the scroll wheel or touchpad to pan around the map. Clicking on an entity will display the entity's properties in the left-hand Properties window.

The + and - keys can be used to zoom in and out of the viewport.

Building

Linux

Install the necessary requirements by running the following command:

sudo apt install build-essential cmake libglfw3-dev libglew-dev libgtk-3-dev

Once the requirements are installed, the program can be built by running the following commands:

git clone --recursive https://github.com/KernelEquinox/SotN-Editor.git
cd SotN-Editor
cmake -B build
cmake --build build

This will create the program in the build/ directory.

macOS

Install the necessary requirements with brew by running the following command:

brew install glew glfw

Alternatively, the requirements can be installed via conda by running the following command:

conda install glew glfw

Once the requirements are installed, the program can be built by running the following commands:

git clone --recursive https://github.com/KernelEquinox/SotN-Editor.git
cd SotN-Editor
cmake -B build
cmake --build build

This will create the program in the build/ directory.

Windows

To build the program on Windows:

1. Install Visual Studio 2022 Community Edition and ensure that Desktop development with C++ is selected in the Workloads tab.

2. Install Git for Windows.

3. Run the following command:

   git clone --recursive https://github.com/KernelEquinox/SotN-Editor.git
   

4. Double-click on the build.bat file to build the project.

This will create the program in the build/Debug/ directory.
