nxdk - the new open source xdk

nxdk is a software development kit for the original Xbox. nxdk is a revitalization of OpenXDK.

Notable features:

  • No complicated cross-compiling or big library dependencies! Builds with make and just needs standard tools and llvm.
  • 3D graphics! nxdk includes and expands on pbkit, a library for interfacing with the Xbox GPU.

Status

nxdk is currently in early stages of development.

Getting Started

Prerequisites

You will need the following tools:

OS-specific instructions for installing these prerequisites can be found in the Wiki

Download nxdk

git clone https://github.com/xqemu/nxdk.git
cd nxdk
git submodule init
git submodule update --recursive

Build Samples

Samples are easily built by running the Makefile in one of the sample directories. Details can be found in the Wiki. nxdk also supports automatic creation of ISO files.

Next Steps

Copy one of the sample directories to get started. You can copy it anywhere you like, but make sure that the NXDK_DIR variable in the Makefile points to correct place. Then, in the directory, you can simply run make.

  • OpenXDK is the inspiration for nxdk, and large parts of it have been reused. (License: GPLv2)
  • Large parts of pbkit, by openxdkman, are included, with modifications. (License: LGPL)
  • A network stack is included based on lwIP (License: Modified BSD)
  • A libc is included based on PDCLib (License: CC0)
  • Large parts of the runtime library are derived from LLVM's compiler-rt library (License: MIT)
  • vp20compiler is based on nvvertparse.c from Mesa (License: MIT)
  • fp20compiler is based on nvparse from the NVIDIA SDK 9.52.
  • The NVIDIA Cg compiler is bundled.
  • extract-xiso developed by in et al. (License: BSD)

Code Overview

  • lib/hal - Barebones Hardware Abstraction Layer for the Xbox, from OpenXDK.
  • lib/net - Network stack for the Xbox based on lwIP.
  • lib/pdclib - Xbox port of PDCLib, a CC0-licensed C standard library.
  • lib/pbkit - A low level library for interfacing with the Xbox GPU.
  • lib/sdl - Xbox ports of SDL2 and SDL_ttf.
  • lib/usb - USB support from OpenXDK. Hacked together parts of an old Linux OHCI stack.
  • lib/winapi - Xbox specific implementations of common useful WinAPI-functions.
  • lib/xboxkrnl - Header and import library for interfacing with the Xbox kernel.
  • lib/xboxrt - Miscellaneous functionality for debugging etc.
  • lib/xlibc-rt - Implementations of supportive functions required at runtime.
  • tools/cxbe - Simple converter for PE executables to the Xbox executable format, from OpenXDK.
  • tools/fp20compiler - Translates register combiner descriptions to Xbox pushbuffer commands.
  • tools/vp20compiler - Translates vertex program assembly to Xbox microcode.
  • tools/extract-xiso - Generates and extracts ISO images compatible with the Xbox (and XQEMU).
  • samples/ - Sample applications to get started.
