What is qemu-uwp-host-builds?

This repository holds prebuilt packages, dependencies, and instructions for Qemu UWP host, a version of the QEMU emulator packaged to run as a Universal Windows Platform app, likely intended for devices such as Xbox where UWP apps can run. The README is sparse and mostly consists of download links and control mappings rather than a full explanation of the project. The main file offered is a msixbundle package, the installer format used for UWP apps on Windows. It depends on a specific Microsoft Visual C++ runtime package that also needs to be installed alongside it. The repository also links out to related projects: one containing modified QEMU 11.0.2 files, one containing the actual UWP host source code, and one for a related Libretro based UWP project, all maintained by the same author. A large part of the README documents how a game controller can be used to interact with the emulated guest system. The left analog stick moves the guest mouse pointer, the directional pad sends arrow key presses, the A button sends Enter, and pressing both triggers together shows or hides an on screen virtual keyboard. Once the keyboard is open, the directional pad moves the selection, the X button presses the selected key, and the Y button closes the keyboard. Pressing both bumpers together toggles whether the controller's mouse and keyboard input is captured by the emulator, similar to a Ctrl+Alt+M shortcut on a desktop. The README does not describe what QEMU itself is or explain any build steps in the main file, pointing instead to separate text files and linked repositories for that detail. No license is stated.
