Developing an emulator is not a simple task, in fact it should be the most complicated and complex programs to develop. I'm sorry to be a troll to some users, I just tried to be clear and open my eyes on the complexity of some projects. Emulators that cover a lot do not tighten. Honestly the best thing you can do is try to port projects to UWP like Retroarch, although I personally prefer emulators that are dedicated exclusively to emulate a system. The fact that the plugins of other free emulators work is very suspicious

Those of ePSXe are a mystery, too many secrets, surely have something to hide from your code as I said before. In fact Henrik, developer of the PSP emulator PPSSPP, ported a version to UWP after many users bothered him to do so.

APPX applications from outside the official store is more tedious than traditional Win32 programs that are easier to install and people are more accustomed to them. No current project like Retroarch, Dolphin or ePSXe will be porting its emulator to UWP because Microsoft has recently changed its policies and is eliminating all emulators from its official store (Windows Store).
