Helps a bit but write operations lock up the system most of the time. This is the only emu with this problem. Edit: redownloaded the binary and it seems a bit more reliable.No you're misunderstanding. "Exit without saving" doesn't copy the sram. "Save & Exit" copies the sram. "Suspend" copies the sram and makes a save state.
I'd highly recommend autosaving for the games it works well with.
