There's no limit on the number of memory exports in a shader on the real Xenos, and exports can be done anywhere, including in loops. Now, instead of deferring the exports to the end of the shader, and assuming that export allocs are executed only once, Xenia flushes exports when it reaches an alloc (allocs terminate memory exports on Xenos, as well as individual ALU instructions with `serialize`, but not handling this case for simplicity, it's only truly mandatory to flush memory exports before starting a new one), the end of the shader, or a pixel with outstanding exports is killed. To know which eM# registers need to be flushed to the memory, traversing the successors of each exec potentially writing any eM#, and specifying that certain eM# registers might have potentially been written before each reached control flow instruction, until a flush point or the end of the shader is reached. Also, some games export to sub-32bpp formats. These are now supported via atomic AND clearing the bits of the dword to replace followed by an atomic OR inserting the new byte/short. |

Xenia - Xbox 360 Emulator
Xenia is an experimental emulator for the Xbox 360. For more information, see the main Xenia wiki.

Quite a few real games run. Quite a few don't. See the Game compatibility list for currently tracked games, and feel free to contribute your own updates, screenshots, and information there following the existing conventions.
Disclaimer
The goal of this project is to experiment, research, and educate on the topic of emulation of modern devices and operating systems. It is not for enabling illegal activity. All information is obtained via reverse engineering of legally purchased devices and games and information made public on the internet (you'd be surprised what's indexed on Google...).
Quickstart
See the Quickstart page.
Building
See building.md for setup and information about the
xb script. When writing code, check the style guide
and be sure to run clang-format!
Contributors Wanted!
Have some spare time, know advanced C++, and want to write an emulator? Contribute! There's a ton of work that needs to be done, a lot of which is wide open greenfield fun.
For general rules and guidelines please see CONTRIBUTING.md.
Fixes and optimizations are always welcome (please!), but in addition to that there are some major work areas still untouched:
- Help work through missing functionality/bugs in games
- Reduce the size of Xenia's huge log files
- Skilled with Linux? A strong contributor is needed to help with porting
See more projects good for contributors. It's a good idea to ask on Discord and check the issues page before beginning work on something.
