add split_map class for mapping keys to values in a way that optimizes for frequent searches and infrequent insertions/removals remove jump table implementation of GetColorRenderTargetFormatComponentCount, it was appearing relatively high in profiles. instead pack the component counts into a single 32 bit word, which is indexed by shifting Add cvar to align all basic blocks to a boundary Add mmio aware load paths liberally apply XE_RESTRICT in ringbuffer related code Removed the IS_TRUE and IS_FALSE opcodes, they were pointless duplicates of COMPARE_EQ/COMPARE_NE and i want to simplify our set of opcodes for future backends More work on LVSR/LVSL/STVR/STVL opcodes Optimized X64 translated code emission, now only compute instrkey once Add code for pre-computing integer division magic numbers Optimized GetHostViewportInfo a little Move args for GetHostViewportInfo into a class, cache the result and compare for future queries. moved GetHostViewportInfo far lower on the profile Add (currently not functional, and very racy) asynchronous memcpy code. will improve it and actually use it in future commits. Add non-temporal memcpy function for huge page-aligned allocations. Used for copying to shared memory/readback hoist are_accumulated_render_targets_valid_ check out of loop in render_target_cache already bound check. Add stosb/movsb code for small constant memcpys/memsets that arent worth the overhead of memcpy/memset
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.
