-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.
+Test with the latest Raspberry Pi OS and RetroPi as of June 9th, 2023.
-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:
+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.
+First, install some tools/libs you'll need:
 <code bash>
-sudo apt-get install git
+sudo apt-get install cmake zlib1g-dev
-sudo apt-get install cmake
 sudo apt-get install libsdl2-2.0-0 libsdl2-dev

-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 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:

 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 ===
-  - 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)
+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.
-  - 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.
+An easy way to replace the boot splash is replacing **/opt/retropie/supplementary/splashscreen/retropie-default.png**
