So I know this discussion is a bit old, but if anyone is still following this...
I'm trying to use the Atari800 emulator on my Anbernic RG503.
It loads the game ok, but it won't make save states through Retroarch. I'm trying to make a save state in the emulator itself.
I can select a directory for a save state, but I can't figure out how to get it to actually save.
I'm also trying to figure out the disk system. I see where I can add disks. I need to swap in a blank disk to save my game, but I can seem to figure out how to do it.
Any tips would be most appreciated.
