The 3-bit field at +24bit in DWORD 1 of the XMA context was named subframe_skip_count but never actually used for skipping subframes. Testing across multiple titles (PGR4, Halo Reach) shows the field might control extra output buffer blocks that must be reserved per decoded frame. Renaming the field to output_buffer_padding to reflect this observed behavior and adding padding to the minimum output space threshold Pdding blocks are reserved from the output budget after each frame is fully consumed, preventing the decoder from overrunning the space that the game expects to remain free. This is still likely not entirely correct but reduces some of the observed noise in current implementation.
Xenia Canary - Xbox 360 Emulator

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.
