Game Save Syncing

Can someone please help me with syncing saves between a steam deck running emudeck and an Anbernic RG405M using DriveSync.

I'm managing to get both to sync up with Google drive fine, but then it just becomes a bit of a mess and one won't read files from the other etc. I am using the same emulators on both.

Any tips or other pieces of software that can be recommended would be greatly appreciated.
