Nintendo DS (DraStic)
To exit DraStic. Press the left analog stick. Then press up or down on the directional pad until the menu becomes visible.
A slightly inconvenient quirk of DraStic is that the cursor appears to have a mind of its own. Pressing up or down once or twice won’t exactly move the cursor as many places in the menu as you expect it to.
Nonetheless, wrestle with the cursor until it is over the “Exit DraStic” option, then press the B button. You will then be taken back to EmulationStation.
(As a side note, press the A button to exit DraStic menu and go back to the game you were playing).
