I've been playing Pokemon Mystery Dungeon: Explorer's of Sky and using both save files and save states to load my game, usually using save states when I need to turn off my computer or load in at a different time, and save files for just saving the game as I forget to save for long stretches of time. So midway through a dungeon (Deep Brine Cave to be specific) I get knocked out, and returned to a halfway point. I close the emulator and go to reopen it, to reload my save file, but the ROM won't open. This has happened before, and last time, when I loaded a save STATE, it worked, but I couldn't reset to any point in order to load the save FILE. I have an idea as to how I could fix this, though. If the emulator loads an actual file, and doesn't override that file when loading a state, I could load a state, go to the main menu (without saving the game), and load the file, which should load the one I want. If that doesn't work, I honestly have no idea what to do.

I'm running desmume version 0.9.11, windows 32 bit version so I can use a controller, but I do also have the 64 bit version if that one will work better. I have all my roms has JAR files that can be loaded through WinRAR and in a separate folder from the one in the Emulator's folder, for organizational reasons. I'm presently running Windows 10 on a laptop, but I can switch to a different device if the laptop is the problem. Thanks in advance.
