RetriX is an emulator front end for UWP, on all the hardware platforms it supports: it serves the same purpose as RetroArch but is built from the ground up to integrate as well as possible with Windows. It can run on desktop, tablet, phone and Xbox One (in dev mode). Holographic, Mixed Reality and Continuum on phone should work too but haven't beed tested.
ReriX supports any LibRetriX conformant cores.
Full compliance with UWP sandboxing
Having cores render to SwapChain panels, allowing XAML and DirectX interop and front ends to use native UWP controls for the UI
Support Windows 10 on all platforms (Desktop, Mobile, Xbox, VR) and architectures (x86, x64, ARM)
Creating a UWP emulation front end for a better experience (proper DPI scaling, native look and feel, fullscreen as borderless window, integration with Windows's modern audio pipeline)
Increasing safety by having emulation code run sandboxed
Create a meaningful use case for UWP sideloading on Windows, since Microsoft has decided to ban emulators from the store
