PS4 Developing Homebrew Unity (Tested with 4.55 but you can build for other versions if you use the right SDK and Unity versions)
PS4 Developing HomeBrew with Unity is set of apps and info I've prepared for you, if you're interested on developing homebrew.
So this is all information you've got available from my repos.
1.- Unity PS4
2.- SDK
Optional: Visual Studio if you want to also build the native code for the unjail plugin. If not you can use unjail with the already built library inluded.
Easy proof of concept to test the Unjail Plugin for Unity PS4. I made this plugin for all Unity PS4 developers to allow an app escalate privileges and get root. ( This feature is part of libHB from cfwprophet ).

An emulator App. It is a GBoy emulator, with many features, and a browser for files integrated. Gamepad and trackpad management. And many features for GUI interaction. Unjail included for testing also. You should connect your USB disk to your PS4 with a folder named ROMS in the root of your USB disk containing all files .gb as roms in there.

A media player with file browser and many other features. Similar to the one before, but this time with more file browsing features, and using common dialogs for PS4, la IME ( Keyboard on screen ). You can use this feature by selecting a file from the list and doing click on the Rename button, which is located on the right side. When you move over to the text box containing the name of the file, the keyboard will be shown. Change whatever you want with the keyboard and then press R2 to confirm. The text will appear in the textbox. So you've got the full procedure complete.

If you want to add Syscall to the Unjail Plugin you will need the full source code. You will need Visual Studio 2015 to build this, and of course the SDK.
