The UI draw log recorded blend state, textures and geometry, which is
enough to say WHICH sprite a draw is and how it composites, and not
enough to answer whether a screen has more than one PASS. A second draw
into an off-screen target, or a resolve of the EDRAM into a texture that
a later full-screen quad samples, both look like just another quad in
the old format.
Three additions, all read straight out of the register file:
mode= RB_MODECONTROL.edram_mode. kCopy (6) is how this GPU issues
a RESOLVE, and it arrives through the same DRAW_INDX packet
as a sprite -- so without this field a resolve was
indistinguishable from a draw.
rt0=/pitch RB_COLOR_INFO's EDRAM tile and format, RB_SURFACE_INFO's
pitch and MSAA. A second target shows up as a different
tile; a half-resolution post-process shows up as a pitch
that is not the screen's.
RESOLVE on a kCopy draw, RB_COPY_CONTROL and RB_COPY_DEST_BASE.
That destination reappearing as a later tex[base=...] is
what 'resolve-and-resample' means stated in addresses,
rather than inferred from the picture.
ps_c[...] the pixel shader's float constants, taken off its OWN
float_bitmap -- the same one the backend uploads from -- so
this is the shader's declared dependency set rather than a
fixed window that could miss the one that matters. Pixel
constants live at SHADER_CONSTANT_256_X and the c# printed
is the index the shader's disassembly uses.
Without the constants, an alpha ramp driven by a shader constant and one
driven by per-vertex colour are the same picture.
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!

Game Compatibility
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.
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.
