-** Experimental ​and for linux pros only **+** Compiling Proton ​and its examples on the Raspberry Pi with GL ES **
  
-These steps are what use to compile stuff by copying things from my Windows computer.  ​A normal user would probably just grab the svn tree.+As a base, 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-libsdl2-dev 
-  * Install cmake on the pi (sudo apt-get install cmake) +</code>
-  * Install SDL2 on the pi (sudo apt-get install libsdl2-dev libsdl2-image-dev ​libsdl2-ttf-dev libsdl2-mixer-dev) +
-  * 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. 
 + 
 +An easy way to replace the boot splash is replacing **/​opt/​retropie/​supplementary/​splashscreen/​retropie-default.png**
