Reply To: Exiting Sega Master System Emulator (Osmose) from controller

if you edit your es_systems.cfg (nano /home/pi/.emulationstation/es_systems.cfg) and scroll down to the Megadrive section you will see the supported rom filetypes. Try adding .sms and .SMS to that line (roms need to be in the Megadrive folder) and Emulation Station should pick them up on reboot.

I’m assuming Picodrive is installed on your setup by the way, it should be the default emulator in es_systems, if not you can install it via the setup script.
