For 4xMSAA 32bpp, samples 2/3 add a +4 byte horizontal offset to the EDRAM address. The old typed buffer code (Buffer<uint4>) implicitly truncated this offset via integer division (>> 2), and the .yw swizzle compensated by selecting odd elements within the aligned uint4 load. After the ByteAddressBuffer conversion, Load4 uses the exact byte address including the +4 offset, shifting the load window by one dword. The .yw swizzle then picks samples from the wrong pixels, causing visual artifacts like vertical streaks in Resident Evil 5. Fix by aligning the load address down to 16 bytes and selecting the swizzle based on whether the address was offset.

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.
