ScummVM Raspberry Pi README
-------------------------------------------------------------------------------

NOTES ON NEEDED DEPENDENCIES

The Raspberry Pi version is linked against the following GNU/Linux libraries 
that may or may not be already installed on a Raspberry Pi GNU/Linux system
and hence needs them installed in your system before running ScummVM on it:
	-SDL2, version 2.0.4 recommended and included. See notes on this below.
	-libVorbis, for OGG music needed by some engines and the fantastic 
	 enhanced music packs by James Woodcock.
	-libJPEG, needed by some engines.
	-libPNG, needed by some engines.

So, if you are in Raspbian, for example, you can install these, except
SDL 2.0.4 by doing:

sudo apt-get install libvorbis0a libjpeg62-turbo libpng12-0

You can look at the other library dependencies by running ldd on the
scummvm executable. They are standard GNU Linux, C++ and Raspberry Pi
Video Core IV libraries that should come installed with your system. 

RUNNING SCUMMVM ON THE RASPBERRY PI SERIES OF MICROCOMPUTERS
------------------------------------------------------------

To launch Scummvm on the Raspberry Pi, run the scummvm.sh script.
It will run the scummvm binary using the SDL2 library in the lib
directory.
You can do so like this:
cd scummvm
./scummvm.sh

Notes on SDL2 version 2.0.4
----------------------------------------------

This version of ScummVM is built against SDL2, and stable version 2.0.4 is 
recommended. Previous versions could have mouse input bugs on the Pi.
Using SDL 1.x on the Pi is buggy, even if a hacky dispmanx (native 2D API)
backend exists, it's not recommended at all.

For this reason, a Pi-version-gnostic of libSDL2-2.0.so.0 (will work on a Pi1,
Pi2 or Pi3) is included until the Raspbian people finally include SDL 2.0.4 
with the system by default.
That's why you should run scummvm using the scummvm.sh script instead of
running the binary directly.
