Proper handling of nans for VMX max/min on x64 (minps/maxps has special behavior depending on the operand order that vmx does not have for vminfp/vmaxfp) Add extremely unintrusive guest code profiler utilizing KUSER_SHARED systemtime. This profiler is disabled on platforms other than windows, and on windows is disabled by default by a cvar Repurpose GUEST_SCRATCH64 stack offset to instead be for storing guest function profile times, define GUEST_SCRATCH as 0 instead, since thats already meant to be a scratch area Fix xenia silently closing on config errors/other fatal errors by setting has_console_attached_'s default to false Add alternative code path for guest clock that uses kusershared systemtime instead of QueryPerformanceCounter. This is way faster and I have tested it and found it to be working, but i have disabled it because i do not know how well it works on wine or on processors other than mine Significantly reduce log spam by setting XELOGAPU and XELOGGPU to be LogLevel::Debug Changed some LOGI to LOGD in places to reduce log spam Mark VdSwap as kHighFrequency, it was spamming up logs Make logging calls less intrusive for the caller by forcing the test of log level inline and moving the format/AppendLogLine stuff to an outlined cold function Add swcache namespace for software cache operations like prefetches, streaming stores and streaming loads. Add XE_MSVC_REORDER_BARRIER for preventing msvc from propagating a value too close to its store or from its load Add xe_unlikely_mutex for locks we know have very little contention add XE_HOST_CACHE_LINE_SIZE and XE_RESTRICT to platform.h Microoptimization: Changed most uses of size_t to ring_size_t in RingBuffer, this reduces the size of the inlined ringbuffer operations slightly by eliminating rex prefixes, depending on register allocation Add BeginPrefetchedRead to ringbuffer, which prefetches the second range if there is one according to the provided PrefetchTag added inline_loadclock cvar, which will directly use the value of the guest clock from clock.cc in jitted guest code. off by default change uses of GUEST_SCRATCH64 to GUEST_SCRATCH Add fast vectorized xenos_half_to_float/xenos_float_to_half (currently resides in x64_seq_vector, move to gpu code maybe at some point) Add fast x64 codegen for PackFloat16_4/UnpackFloat16_4. Same code can be used for Float16_2 in future commit. This should speed up some games that use these functions heavily Remove cvar for toggling old float16 behavior Add VRSAVE register, support mfspr/mtspr vrsave Add cvar for toggling off codegen for trap instructions and set it to true by default. Add specialized methods to CommandProcessor: WriteRegistersFromMem, WriteRegisterRangeFromRing, and WriteOneRegisterFromRing. These reduce the overall cost of WriteRegister Use a fixed size vmem vector for upload ranges, realloc/memsetting on resize in the inner loop of requestranges was showing up on the profiler (the search in requestranges itself needs work) Rename fixed_vmem_vector to better fit xenia's naming convention Only log unknown register writes in WriteRegister if DEBUG :/. We're stuck on MSVC with c++17 so we have no way of influencing the branch ordering for that function without profile guided optimization Remove binding stride assert in shader_translator.cc, triangle told me its leftover ogl stuff Mark xe::FatalError as noreturn If a controller is not connected, delay by 1.1 seconds before checking if it has been reconnected. Asking Xinput about a controller slot that is unused is extremely slow, and XinputGetState/SetState were taking up an enormous amount of time in profiles. this may have caused a bit of input lag Protect accesses to input_system with a lock Add proper handling for user_index>= 4 in XamInputGetState/SetState, properly return zeroed state in GetState Add missing argument to NtQueryVirtualMemory_entry Fixed RtlCompareMemoryUlong_entry, it actually does not care if the source is misaligned, and for length it aligns down Fixed RtlUpperChar and RtlLowerChar, added a table that has their correct return values precomputed |

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.

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.
