RPCS3 Support

It might be premature, but I've been working on getting RPCS3 working for PS3 support. Their project has come a long way and seems to be working a lot better now. I am working on a way to launch the emulator in headless mode and directly launch the game.

There are a few uncertainties... to include how RPCS3 inventories the games and where that is stored. If I get some answers to these questions, do you think adding support for PS3 would be possible?

The issue names no repository files, tests, or entry points. Start by confirming RPCS3's headless launch behavior and how it inventories and stores games, then inspect the repository's existing emulator-launch support. Done would mean a defined and working path for adding PS3 support, including direct game launching.
