<p>To play a game, simply open a ROM by selecting "Open" in the File Menu (or press Ctrl+O). (See <aclass="rvts18"href="Gamefilecompatibility.html">Game Compatibility</a> for information regarding file types that are compatible with FCEU.)</p>
<p>In emulation, a savestate (alternatively called freeze state or game freeze) is a snapshot of all of an emulated device's state information at a given moment. This makes it possible to pause emulation, and restart it later, even in another instance of the emulator, or to test the emulated machines reaction to different series of inputs using the saved state as a common starting point. </p>
<p>To make a savestate press shift + F1-F10 to save to a save slot (0-9). Or select a save slot with the number keys (0-9) and select the quick save command (Default hotkey is "I")</p>
<p>To load a savestate press F1-F10. Or select a save slot with the number keys (0-9) and loadstate by navigating to File > Savestate > Loadstate or by pressing the loadstate hotkey (Default hotkey is "P").</p>
<p>If you load a state by accident, you can right-click and select "Undo Loadstate" to restore the emulator back to the state it was in before the loadstate. Upon using undo loadstate, a redo loadstate will appear as an option. </p>
<p>If you make a savestate, it will overwrite the existing savestate for that slot. You have the option to undo this and restore the previous savestate file by right-clicking and selecting undo savestate. Once you undo, you will have the option to redo savestate to restore the savestate that you made. You can also map a <aclass="rvts18"href="MapHotkeys.html">hotkey</a> to this function, by default it's mapped to Ctrl+Z.</p>
