Adds audit_mem_watch_addr (comma-separated hex guest VAs) and audit_mem_watch_size (1/2/4/8 bytes) to watch arbitrary guest memory locations at runtime. Once per vblank, GraphicsSystem::MarkVblank() reads each VA big-endian via Memory::TranslateVirtual and emits an XELOGKERNEL "AUDIT-MEM-WATCH" line on every value change vs the prior frame (same greppable log stream as AUDIT-HLC / AUDIT-MEM-READ). Mechanism is poll / value-change: it captures WHEN a value changes (vblank index) but NOT the writer guest-PC; pair with audit_jit_prolog_pc on a suspected writer to recover the PC. Heap VAs vary per run/engine, so they are supplied at runtime via cvar/CLI. Default empty => disabled => zero overhead and no emulation-behavior change. Validated against the controller vsync "clock A" field (+0x58): the watch fires once per change, advancing monotonically in lockstep with vblanks. Game still boots and runs muted with the cvar unset.

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

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.
