Remove the logger_ != nullptr check from shouldlog, it will nearly always be true except on initialization and gets checked later anyway, this shrinks the size of the generated code for some Select specialized vastcpy for current cpu, for now only have paths for MOVDIR64B and generic avx1 Add XE_UNLIKELY/LIKELY if, they map better to the c++ unlikely/likely attributes which we will need to use soon Finished reimplementing STVL/STVR/LVL/LVR as their own opcodes. we now generate far less code for these instructions. this also means optimization passes can be written to simplify/remove/replace these instructions in some cases. Found that a good deal of the X86 we were emitting for these instructions was dead code or redundant. the reduction in generated HIR/x86 should help a lot with compilation times and make function precompilation more feasible as a default Don't static assert in default prefetch impl, in c++20 the assertion will be triggered even without an instantiation Reorder some if/else to prod msvc into ordering the branches optimally. it somewhat worked... Added some notes about which opcodes should be removed/refactored Dispatch in WriteRegister via vector compares for the bounds. still not very optimal, we ought to be checking whether any register in a range may be special A lot of work on trying to optimize writeregister, moved wraparound path into a noinline function based on profiling info Hoist the IsUcodeAnalyzed check out of AnalyzeShader, instead check it before each call. Profiler recorded many hits in the stack frame setup of the function, but none in the actual body of it, so the check is often true but the stack frame setup is run unconditionally Pre-check whether we're about to write a single register from a ring Replace more jump tables from draw_util/texture_info with popcnt based sparse indexing/bit tables/shuffle lookups Place the GPU register file on its own VAD/virtual allocation, it is no longer a member of graphics system |

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.
