Select the game for which you want to record the video and then click "Open" to load it in the emulator.
Click "Tools" from the menu bar and then hover your mouse cursor over the "Record" option.
Click "Start AVI recording" and then enter a file name for the video file. Select a location on your computer where you want to store the recorded video and then click "Save."
