QUITFOCUS
If enabled this will cause Retroarch to quit completely when it loses focus (eg. when the home button is pressed). This is useful when you are using an alternative launcher such as Kodi because it will make the home button function as an alternative quit key, return to the alternative launcher, and then allow for a different game to start instead of returning to the current session.
HIDEMOUSE
Normally it is not possible to hide the mouse cursor if you have attached an external mouse to your Android unit. This makes it difficult to implement mouse support in the Android version of Retroarch because you will end up having two mouse cursors on the screen. NVIDIA has implemented extensions on the SHIELD that allows for hiding the mouse cursor. If this parameter is provided when starting Retroarch it will check for these extensions and if available it will hide the mouse cursor.
(I am almost done with adding mouse support to the Android input driver and will be submitting a suggestion for this very soon)
Basically it saves the apk file (that is used ONCE) in the external SD but all the data files are created in the same location in the internal partition
Having it as preferExternal causes installation issues on some devices (have to remove the SD card to install the app..., then insert again)
Split up into separate modules to avoid the pain with cross-defines from
C and C++.
Move to c++_static STL. It's the recommended way since a while back and
fixes some build issues as well.
