Compiling a list of ROM folder names for every retro handheld devices that’s using RetroArch as the emulation program takes a lot of time. It isn’t really worth the effort to educate users on which system is going to work best for each device, so when I’m a newbie, I really appreciate the effort both Onion dev team and Miyoo Mini’s community make to describe the supported emulators and rom formats for the famous retro device.
So, based on my experience with numerous retro handheld emulators, perhaps I will try to create a list of ROM folder names for everyone to access. But first, I believe you should check these articles:

If your system is case sensitive and needs ROM folder names to be all capitalized, you can google for an online convert case website to change.
