If you prefer using Python environment management tools and need to set up the Node.js dependencies for development, the recommended way to run Saka04Editor is by using uv and pnpm to manage the project dependencies:

uv venv --python python3.13
uv sync
pnpm install
pnpm run desktop:prod

Currently, the editor supports two modes:

• Open and modify memory card save files.
• Supports full in-game data editing (players, teams, etc.).

• Modify game data in real time while connected to a running PCSX2 emulator.
• Offers the same editing capabilities as save file mode — now live while the game is running.
