Previously, for mips, the dimensions of the texture weren't rounded to powers of two before calculating the mip tail extent, resulting in the mip tail for a 260 blocks tall texture, that contains mips ending at Y of up to 36, having the Y extent calculated as 32. With rounding to powers of two, it would have been 64. However, with the GetTiledAddressUpperBound functions, none of this is necessary at all (and neither is rounding the extents in TextureGuestLayout::Level to 32x32x4 blocks) - using the same code for calculating the XYZ extents of tiled textures as for linear textures now, which, for the mip tail, calculates the actual maximum coordinates of the mips stored in it - and rounding to tiles is done internally by GetTiledAddressUpperBound.

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:
- 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.
