tldr; It is possible to use a CM4 Lite (no eMMC) with an adapter board on the Freeplay CM3. The process involves using a fresh Retropie image and manually installing the changes required from the Freeplay-Support repo on top of it. The CM4 will not fit inside the GBA so a few mods to the case are also needed. Finally, the adapter board I used does not connect the pins required for the "L2R2 Dual Analog (4 ADC) Add-On Board" so individual wires must be rerouted in order for the analog joysticks and L2 and R2 to work. A low profile heatsink fits if it's carefully sanded off.

The purpose of this post is to log my progress while I try to connect a CM4 Lite (no eMMC) to my Freeplay
So far I was able to make a fresh retropie image (buster) boot up on the Freeplay. There seems to be something missing that keeps sending current to the pi after holding the switch for 5 seconds.
I manually installed everything that's in the Full_Install.sh script that's in Freeplay-Support repo but it still won't stay on. And I found the script that does it when shutting it down but nothing similar for turning it on.
Any help would be greatly appreciated
