Implements resolution scale selection, per surface, for both backends. Surfaces with pitches at or below the defined threshold render at 1x1 while everything else scales. This catches downscaled post-process chains that gain nothing from upscaling and often break from it. 0 leaves everything scaled. Class is a function of pitch and MSAA samples, baked into RenderTargetKey, and the caches create, clear, transfer, and dump per that class. Transfer shaders carry separate dest and source scales. Pixel shaders get a modification bit so 1x1 draws translate with 1x addressing for param_gen and memexport, and per-draw viewports, point sizes, and divisors pull from RT cache instead of draw_resolution_scale_x/y. 1x1 resolves copy unscaled data straight into shared memory and unmark the range from scaled resolve page tracking, so textures pick up the correct copy. Readback resolves skip downscaling when appropriate. ZPD normalizes per segment so mixed reports don't undercount. Host RT only. ROV/FSI EDRAM layout assumes a single global scale and, while implementing support for scale selection is probably doable, it's likely an enormous task.
Xenia Canary - Xbox 360 Emulator
Xenia Canary is an experimental fork of the Xenia emulator. For more information, see the Xenia Canary wiki.

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.
