Sylpheed RE agent ab3203f792 RE: log a CONTENT hash beside every sampled texture
A base address cannot distinguish 'the guest decoded a new frame' from 'the
guest rotated to the next buffer of a triple-buffered set' -- a rotating
buffer visits the same three addresses either way. Reading a clean
one-base-change-per-present as one decode per present is how
docs/re/guest-frame-rate-measured.md reached a conclusion it had to
withdraw.

h=<FNV-1a over 4096 sampled bytes>, omitted rather than faked when the
address does not translate, so a missing hash cannot read as a matching
one. Sampled rather than full: a 1280x720 plane is 900 KB and hashing all
of it per draw would change the thing being measured.

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! Please check the FAQ page before asking questions. We've got jobs/lives/etc, so don't expect instant answers.

Discussing illegal activities will get you banned.

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:
