Reverse-engineering aid for decoding game mesh formats against GPU ground
truth. When the `log_draws` cvar is set, each distinct draw's primitive
type, index buffer (guest base / count / format / endianness), and full
per-stream vertex declaration (fetch-constant base + stride, and every
element's format + offset) is written to xenia_re_draws.log.
- command_processor.{h,cc}: CommandProcessor::LogDrawForRE(), no-op unless
the cvar is set. De-dups by the vertex-declaration fingerprint (shader +
primitive + element formats/offsets), so animated UI that redraws the
same format into fresh buffers every frame collapses to one record --
keeping it near-free (an earlier address-keyed de-dup flooded the log and
stalled the GPU thread). Capped at 4096 distinct formats.
- pm4_command_processor_implement.h: call it from ExecutePacketType3Draw
after IssueDraw (so the vertex shader has been analyzed). Backend-agnostic
base path -- works for the Vulkan build.
Used to confirm Project Sylpheed's XBG7 mesh layout (triangle list, pos
f32x3 / normal f16x4 / uv f16x2, variable stride).

Xenia Canary - Xbox 360 Emulator
Xenia Canary is an experimental fork of the Xenia emulator. For more information, see the Xenia Canary wiki.
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!

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.
