tvOS port

[marekvi]

Hi,

I am working on a PPSSPP port for the Apple TV devices. You can check it here https://github.com/marekvi95/ppsspp in the tvos-fork branch. The only requirement is a game controller supported by Apple TV (MFi or iCade). Installation instructions are in the tvos subfolder README.md. However it's still under development so it might be broken sometimes.

It runs just fine now, even without the JIT on Apple TV 4k with the A10X SoC. Problem is with the more resource demanding games like God of War where FPS drops occasionally.

I've used GCDWebServer (HTTP server) implementation from Provenance project for uploading games to Apple TV.

Please note that this is my first attempt with the Xcode and Objective-C.
