Alt + F5 = Save State
Alt + F6 = Previous SLot
Alt + F7 = Next SLot

Alt + Enter = Switch between full screen and windowed modes.

Controls can be set in game (usually Arrow Keys and Space/R-Alt/R-Ctrl)

By default I have enabled the DOSBox that allows you to save and load states in each game (by setting a different slot if you want more than one save point or game), you can change the DOSBox folder or .cmd location if you want smoother graphics or to use the original DOSBox release.
