-** Experimental and for linux pros only **
+** Compiling Proton and its examples on the Raspberry Pi with GL ES **
-These steps are what I use to compile stuff by copying things from my Windows computer.  A normal user would probably just grab the svn tree.
+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)
-Steps:
+If you REALLY want to use a standard Raspbian stretch install you can, just do these commands first to get ready:
-* Install linux tools for Windows, rsync and ssh should work from the command line
+<code bash>
-* Setup a ssh key pair so you don't have to type passwords
+sudo apt-get install cmake
-* Edit SetupVars.bat and edit the IP to the pi
+sudo apt-get install libsdl2-2.0-0 libsdl2-dev
-* Install development tools on the pi (sudo apt-get update && apt-get install build-essential)
+</code>
-* Run CopyStuffToPi.bat.  There should now be a ~/proton tree on the pi
-* RTBareBones/CopyStuffToPiAndCompileLoop.bat and it should update that example and compile it in a loop
+Also, I think the GL driver needs to be set to "Legacy" to work, which is the default, but worth mentioning if you've changed it using raspi-config.
-If you look at the RTBarebones/linux dir you'll see the CMakeLists.txt file autodetect the pi and sets up GLES 1.1 headers stuff for it.
+---- End Raspbian stretch part ----
+First, make sure you gave git installed. SSH into your PI and:
+<code bash>
+sudo apt-get install git
+</code>
+Next, install Proton and compile its RTPack utility:
+<code bash>
+cd ~
+git clone https://github.com/SethRobinson/proton.git
+</code>
+Now let's build Proton's RTPack utility, will come in handle later.
+<code bash>
+cd ~/proton/RTPack/linux
+sh linux_compile.sh
+</code>
+Now let's compile and run RTBareBones:
+<code bash>
+cd ~/proton/RTBareBones/linux
+sh linux_compile.sh
+cd ../bin
+./RTBareBones
+</code>
+If that worked, enjoy the spinning triangle and text stretching!
+Now let's do RTSimpleApp, same thing but it needs SDL2_mixer for its audio, so let's get that installed:
+<code bash>
+sudo apt-get install libsdl2-mixer-dev
+</code>
+Great.  Now we compile and run like before, but we're adding a step - compiling media with the RTPack utility.
+<code bash>
+cd ~/RTSimpleApp/linux
+sh linux_compile.sh
+cd ../media
+sh update_media.sh
+cd ../bin
+./RTSimpleApp
+</code>
+If that worked, enjoy the app.  If it didn't... off to the forums and yell at Seth!
+=== State of Proton on the Pi ===
+  - It runs fullscreen only both in or out of the desktop environment
+  - 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]])
+Hint: Using the RetroPi dist? You can edit the text file **/opt/retropie/configs/all/autostart.sh** and comment out where it runs emulationstation and change that to run your own app - or nothing at all, so it drops into the shell on boot.
