-** Experimental and for linux pros only **
+** Compiling Proton and its examples on the Raspberry Pi with OpenGL 2**
-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.
+Test with the latest Raspberry Pi OS and RetroPi as of June 9th, 2023.
-Steps:
+These should run both in the desktop GUI, or directly from bash. (Fullscreen)  I guess it's all identical to running on Ubuntu Linux/etc these days, no special stuff is needed.
-  * Install linux tools for Windows, rsync and ssh should work from the command line
+First, install some tools/libs you'll need:
-  * Setup a ssh key pair so you don't have to type passwords
-  * Edit SetupVars.bat and edit the IP to the pi
-  * Give the video card more memory on the pi.  Run raspi-config and give it 128 or 256 (good for the pi3)
-  * Install cmake on the pi (sudo apt-get install cmake)
-  * 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
+<code bash>
+sudo apt-get install cmake zlib1g-dev
+sudo apt-get install libsdl2-2.0-0 libsdl2-dev
+</code>
-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.
+Don't forget git!
+<code bash>
+sudo apt-get install git
+</code>
+Next, install Proton.
+<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 to build and optimize resources.
+<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!  It got 300+ fps on my Pi 4. Starting it from an ssh session worked for me as well.
+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!
+=== Note from Dec 3rd, 2023 ===
+I updated things so pulseaudio is used by default instead of alsa when compiling on a pi, this fixes audio on the latest Raspberry Pi OS.  (in AudioManagerSDL.cpp)
+=== State of Proton on the Pi ===
+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**
