 ** Compiling Proton and its examples on the Raspberry Pi with GL ES **
-As a base, I started with RetroPi (the image from 7/28/2018) on a Raspberry 3 B.  I should try it with a vanilla Raspbian Stretch install and see if that works too.
+As a base, I started with a [[https://retropie.org.uk/download/|RetroPi image]] [[https://www.balena.io/etcher/|written]] to an SD card (tested with 4.4 on 1/28/2019) on a Raspberry 3B.  Why?  Because it comes with SDL2 pre-installed and pre configured so SDL will properly send mouse and keyboard input which saves a lot of hassle. (don't ask me why, but the version the standard stretch has on apt-get doesn't)
-Update on Jan 28th 2019:  I did try this with Raspbian Stretch 4.14, you need to run these commands first to get it working:
+If you REALLY want to use a standard Raspbian stretch install you can, just do these commands first to get ready:

-sudo apt-get install git
 sudo apt-get install cmake
 sudo apt-get install libsdl2-2.0-0 libsdl2-dev

 === State of Proton on the Pi ===
   - It runs fullscreen only both in or out of the desktop environment
-  - No mouse or keyboard input (SDL isn't doing its job, see below)
+  - If SDL isn't compiled a certain way, mouse and keyboard won't work right. (use the RetroPi dist!)
+  - Even though mouse and keyboard can work, there is no mouse cursor, you'd need to draw it yourself
   - Video acceleration works, audio works (see my [[https://www.youtube.com/watch?v=bk6jVk7t4i4|Atari PaperCart project]])
-SDL apparently can be tweaked to actually work with mouse and keyboard input but it requires some tricky stuff [[https://hg.libsdl.org/SDL/file/093b58f5de3c/docs/README-raspberrypi.md|last I checked]].  Might be easier for Proton to just do its own input handling via libudev/libusb or something, not sure.
