-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)
+Test with the latest Raspberry Pi OS and RetroPi as of June 9th, 2023.
-If you REALLY want to use a standard Raspbian stretch install you can, just do these commands first to get ready:
+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 cmake
+sudo apt-get install cmake zlib1g-dev
 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.

-=== State of Proton on the Pi ===
+=== Note from Dec 3rd, 2023 ===
-  - 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]])
+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**
