Just install vanilla Raspberry Pi OS for your Pi 5, and install RetroPie using retropie-setup

install lr-retro8 using RetroPie-Setup (easy way to get a Pico-8 menu option we can modify to our own ends)

Download the Rasberry Pi distro of pico8 and copy the unzipped pico-8 dir to /opt/retropie/ports/

maybe sudo chmod -R 755 /opt/retropie/ports/pico-8/

touch ~/RetroPie/roms/pico8/Splore.p8, launching this dummy cart will launch splore. IDK what zzzsplore.p8 is but it doesn't work and looks ugly in the EmulationStation UI.

Hardware PWM on the Raspberry Pi 5 b

Since PWM is a little fraught with gotchas, this is mostly a message to future me-
