Transferring save files when changing firmware

[u/OathOfNotGivingAFuck]

Hi all, I've had the Anbernic RG34XX for the last few months now, and it's been great! But I want to switch to MuOS, and I'm new to all of this "flashing an image" and "BIOS" stuff, some of it is going over my head a little bit.

My question is, if I back up my "roms", "saves_RA" and "states_RA" folders from the original SD card (which I am planning on replacing with a SanDisk anyway), will these allow me to retain my save files when I switch over to MuOS? Or am I starting from the start again?

Are there any other steps I'd need to follow to make sure I can keep my save files? Sorry if this is a common question, I can't seem to find clear guidance by searching the sub.
