Triang3l a06be03f1b [GPU] Cleanup definitions of some registers
VS/PS_NUM_REG is 6-bit on Adreno 200, and games aren't seen using the
bit 7 to indicate that no GPRs are used. It's not clear why Freedreno
configures it this way.

Some texture fetch fields were deprecated or moved during the development
of the Xenos, reflect that in the comments.

Add definitions of the registers configuring the conversion of vertex
positions to fixed-point. Although there isn't much that can be done with
it when emulating using PC GPU APIs, there are some places in Xenia that
wrongly (though sometimes deliberately, for results closer to the behavior
of the host GPU) assume that the conversion works like in Direct3D 10+,
however the Xenos supports only up to 4 subpixel bits rather than 8. The
effects of this difference are largely negligible, though.

Also add more detailed info about register references and differences from
other ATI/AMD GPUs for potential future contributors.

Xenia - Xbox 360 Emulator

Xenia is an experimental emulator for the Xbox 360. For more information, see the main Xenia wiki.

Interested in supporting the core contributors? Visit Xenia Project on Patreon.

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.

Quite a few real games run. Quite a few don't. 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.

Disclaimer

The goal of this project is to experiment, research, and educate on the topic of emulation of modern devices and operating systems. It is not for enabling illegal activity. All information is obtained via reverse engineering of legally purchased devices and games and information made public on the internet (you'd be surprised what's indexed on Google...).

Quickstart

See the Quickstart page.

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:

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.
