Questions

i am unsure if there are any hotkeys in the emulator, however if you need to take screenshots then you can do it without the emulator. for example you can press printscreen on your keyboard then paste in paint or you can install a program that takes snapshots of your screen

what do you mean by save\load? as i know the emulator doesnt support save state and load state and if you want to save then you have to save in the game by using the game's save option
