+There are two options available for RetroArch, you can use CMake
+to build the core, or you can use the older Makefile based setup.
+The Makefile based setup is for the older RetroArch build system.

+##### CMake
+
+Same as above for _CMake_, the RetroArch specific target is
+in this case `mu_libretro`. This will output a file accordingly.
+Note that if you are using a system which uses static binaries,

+here <https://git.libretro.com/libretro/Mu/-/pipelines>.

  4. Run emu and press start button
 
 #### For RetroArch
- 1. Download "Palm OS(Mu)" from "Online Updater->Core Updater"
- 2. Go back, select "Load Core", select "Palm OS(Mu)"
- 3. Copy "palmos41-en-m515.rom" and "palmos52-en-t3.rom" to the RetroArch system directory

+        downloaded core from another source and place it within
+        RetroArch's `cores/` directory. If you do this, remember
+        to also install `mu_libretro.info` (which is located
+        in `libretroBuildSystem`) to the directory as well so
+        it knows which files are supported.
+ 2. Go back, select _Load Core_, select _Palm OS (Mu)_
+ 3. Copy `palmos41-en-m515.rom` to the RetroArch system directory
+    1. For experimental Palm OS 5 support: `palmos52-en-t3.rom`.
