# NocturneRecomp

Static recompilation of **Castlevania: Symphony of the Night** (Xbox Live Arcade) for Windows
and Linux, built on the [ReXGlue SDK](https://github.com/birabittoh/rexglue-sdk).

This project converts the Xbox 360 PowerPC `default.xex` into native x86_64
code at build time, then wraps it with a small host runtime (logging,
overlays, hooks) so the game runs natively and can be modded like a PC port.

**You must own the game.** This project does **not** ship any copyrighted code, data, or assets. You provide your own legally dumped game.

Feel free to visit NocturneRecomp's [official Discord server](https://discord.gg/DJe2pXMH7S) if you need any help.

# Get the game on [Goopie](https://goopie.xyz/#/library/nocturnerecomp)!

## Using a prebuilt release

Get the latest stable build from the [Releases](../../releases/latest) page.

Nightly builds are available from [CI artifacts](https://nightly.link/birabittoh/NocturneRecomp/workflows/ci/main?preview).

Just extract the archive, run the executable and it will prompt you to extract the game.

## Building from scratch

### 0. Install dependencies

#### Linux (Arch/CachyOS)
```bash
paru -S clang20 cmake ninja vulkan-headers
```

#### Windows
```powershell
scoop install llvm cmake ninja
```

### 1. Clone

```bash
git clone https://github.com/birabittoh/NocturneRecomp
cd NocturneRecomp
```

### 2. Download the ReXGlue SDK

```bash
python scripts/download-sdk.py --pinned
```

### 3. Provide your game

Place your legally dumped XBLA package (the `LIVE`/STFS file) into `game/`, then extract it into `assets/`:

```bash
python scripts/extract_game.py
```

`assets/default.xex` must exist before running codegen.

### 4. Build

python scripts/build.py --tu /path/to/TU_*
```
