Xenia - Xbox 360 Emulator Research Project
==========================================
2013-01-10 23:20:45 +00:00
2013-01-10 23:22:20 +00:00
Xenia is an experimental emulator for the Xbox 360. It does not run games (yet),
and if you are unable to understand that please leave now.
Currently supported features:
* Nothing!
Coming soon (maybe):
* Everything!
## Quickstart
git clone https://github.com/benvanik/xenia.git
cd xenia && source xeniarc
xb setup
xb build
./bin/xenia-run some.xex

## Requirements
2013-01-10 23:22:20 +00:00
You must have a 64-bit machine for building and running the project. Always
run your system updater before building and make sure you have the latest
video drivers for your card.
#### Windows
Ensure you have the latest patched version of Visual Studio 2010, the
Windows SDK, the full DirectX SDK, and the Kinect SDK.
* Visual Studio 2010 (not sure Express will work)
* [Visual Studio 2010 SP1](http://msdn.microsoft.com/en-us/vstudio/aa718359)
* [Windows SDK](http://www.microsoft.com/download/en/details.aspx?id=8279)
* [DirectX SDK](http://msdn.microsoft.com/en-us/directx/)
* [Kinect SDK](http://www.kinectforwindows.org/download/)
* [Python 2.7](http://www.python.org/download/releases/2.7.3/)
Make sure that Python is on your PATH.
Use the Visual Studio 2010 x64 command prompt.
There's a bug in VC++ that breaks with an internal error when building LLVM.
Change line 87 of include/llvm/ADT/StringExtras.h:
```
-static inline std::string utostr(uint64_t X, bool isNeg = false) {
+static __declspec(noinline) std::string utostr(uint64_t X, bool isNeg = false) {
```

#### OS X
Only tested on OS X 10.8 (Mountain Lion).
* [Xcode 4](http://developer.apple.com/xcode/) + command line tools
* [Homebrew](http://mxcl.github.com/homebrew/)
## Building
A simple build script is included to manage basic tasks such as building
dependencies.
./xenia-build.py --help
The `xeniarc` bash file has some aliases that save some keypresses.
source xeniarc
xb -> python xenia-build.py
xbb -> python xenia-build.py build
xbc -> python xenia-build.py clean
### Commands
#### setup
Run this on initial checkout to pull down all dependencies and setup LLVM.
xb setup
#### pull
Does a `git pull` in addition to updating submodules and rebuilding dependencies
and gyp outputs. Use this, if possible, instead of git pull.
xb pull
#### gyp
Updates all of the supported gyp projects. If you're using Visual Studio or
Xcode to build or debug your projects you'll need to run this after you change
gyp/gypi files.
xb gyp

#### xethunk
Updates the checked-in `src/cpu/xethunk/xethunk.bc` and `xethunk.ll` files.
This is only required if changes are made to the xethunk files. The results
should be checked in.
#### build
Builds all xenia targets using ninja. Release is built by default; specify
`--debug` to build the debug configuration.
xb build
xb build --debug
#### clean
Cleans just xenia outputs from the build/ directory. A following build will just
have the rebuild xenia and not all of the dependencies.
xb clean
#### nuke
Cleans up xenia outputs as well as all dependencies. A full build will be
required after this - including LLVM - so only do this if you want to reclaim
your disk space or something is really wrong.
xb nuke
## Running
Use the wrapper shell scripts under `bin/` to run tools. They will ensure the
tools are built (but not that they are up to date) before running and allow
switching between the debug and release variants with `--debug`.
### xenia-info
Dumps information about a xex file.
./bin/xenia-info some.xex
### xenia-run
2013-01-10 23:22:20 +00:00
Runs a xex.
2013-01-10 23:22:20 +00:00
./bin/xenia-run some.xex
