## Building

Needs Visual Studio 2022 (C11) and CMake 3.20+.

```bash
cmake -S doa3 -B doa3/build
cmake --build doa3/build --config Release --target doa3
```

The binary lands in `doa3/build/release/DOA3.exe`.

## Running

Download the latest release from the releases tab

Game files are **not** included. On first launch of DOA3.exe, select your legally obtained copy of Dead or Alive 3 (USA) in `.xiso` or
`.xiso` format. Asset files are automatically extracted, save data is created, and then the game will be ready to play once this completes.

Press the **Escape** key to open the overlay menu. This has online, controller mapping, and other settings.

## Credits

This project stands on the amazing work of **Ned Heller (sp00nz)**:

- [xboxrecomp](https://github.com/sp00nznet/xboxrecomp) — the static recompilation toolkit this is
  built with: the x86→C lifter, XBE parser, kernel layer, D3D8→D3D11 compat layer, and NV2A
  translator.
- [burnout3](https://github.com/sp00nznet/burnout3) — the first static recompilation of a retail
  original Xbox game, and the reference this port follows. The NV2A→D3D11 push-buffer translator
  comes from it directly.

Also relies on:

- [Cxbx-Reloaded](https://github.com/Cxbx-Reloaded/Cxbx-Reloaded) — used as a debugging oracle;
  Breakpointing the emulator and diffing its behaviour against ours found most of the bugs.
- [xemu](https://github.com/xemu-project/xemu) — NV2A documentation and the texture unswizzling
  algorithm.
- [Xbox Dev Wiki](https://xboxdevwiki.net) — XBE format, kernel exports, NV2A registers.
