I haven't tried other games, I've heard that .10 isn't very good, and I tried both in-game saving and save states. The former didn't create a save file and the latter said there was an error.
I'm using Desmume 0.9.9. I just started playing the Miles Edgeworth 2 patched game, but my emulator does not make save files. When I try to save state, it says there is an error.
What is wrong with my emulator? How can I save?
