niilo/VITAplus ? reverse-engineered prompt

Build me an experimental PlayStation Vita emulator from this codebase that can launch on Windows, Linux, macOS, and Android.

I want a simple, usable app that can open Vita homebrew and as many commercial games as it reasonably can, with a basic game list, install and launch flow, graphics and audio working, and clear error messages when something fails. If there are missing pieces or outdated dependencies, please figure them out and get the project building cleanly, then make the app run well enough to test with a few sample titles.

Please keep the focus on getting a working emulator experience first, not polish. Make sure the build and run steps are straightforward, and update anything needed in the repo so I can compile it and try it locally. If you need current docs or setup details, look them up online and follow the latest guidance.
