properly byteswap r13 for spinlock Add PPCOpcodeBits stub out broken fpscr updating in ppc_hir_builder. it's just code that repeatedly does nothing right now. add note about 0 opcode bytes being executed to ppc_frontend Add assert to check that function end is greater than function start, can happen with malformed functions Disable prefetch and cachecontrol by default, automatic hardware prefetchers already do the job for the most part minor cleanup in simplification_pass, dont loop optimizations, let the pass manager do it for us Add experimental "delay_via_maybeyield" cvar, which uses MaybeYield to "emulate" the db16cyc instruction Add much faster/simpler way of directly calling guest functions, no longer have to do a byte by byte search through the generated code Generate label string ids on the fly Fix unused function warnings for prefetch on clang, fix many other clang warnings Eliminated majority of CallNativeSafes by replacing them with naive generic code paths. ^ Vector rotate left, vector shift left, vector shift right, vector shift arithmetic right, and vector average are included These naive paths are implemented small loops that stash the two inputs to the stack and load them in gprs from there, they are not particularly fast but should be an order of magnitude faster than callnativesafe to a host function, which would involve a call, stashing all volatile registers, an indirect call, potentially setting up a stack frame for the arrays that the inputs get stashed to, the actual operations, a return, loading all volatile registers, a return, etc Added the fast SHR_V128 path back in Implement signed vector average byte, signed vector average word. previously we were emitting no code for them. signed vector average byte appears in many games Fix bug with signed vector average 32, we were doing unsigned shift, turning negative values into big positive ones potentially |

Xenia - Xbox 360 Emulator
Xenia is an experimental emulator for the Xbox 360. For more information, see the main Xenia wiki.
Interested in supporting the core contributors? Visit Xenia Project on Patreon.
Come chat with us about emulator-related topics on Discord.
For developer chat join #dev but stay on topic. Lurking is not only fine, but encouraged!
Please check the FAQ page before asking questions.
We've got jobs/lives/etc, so don't expect instant answers.

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.
