…and why Puerto Rico is included.

Did you try increasing the cache size?

Yep this is the way.

Keep all your saves in one folder then you can switch devices freely anf pick up where you left off. Like one playing on the TV, using the PC for GPU/streaming, and phone for mobile play.

I already had Syncthing set up on my PC, server, and phone, so adding another folder for game saves was a simple addition.

Definitely worth it to take an hour to set up and test everything so you never need to think about it again

Syncthing has all these features for free and works on mobile too. Just instruct your emulator to save to a Syncthing folder or create a new one. Has the added benefit of being able to sync any other type of file too, not just saves
