Do not get used to save states when using emulators. First of all, it kinda takes away the point of actual in-game save points. Second, if you forget whether to load the in-game save or the save state, and then fuck your entire progress up because you loaded a save state that has less progress than the actual save file, you can't go back to that save file because you loaded the game at a point where that save file did not exist yet.
