+9. Memory Snapshots
+-------------------
+
+ Since version 1.3 DS81 now supports basic memory snapshots. When you
+ select the "SAVE MEMORY SNAPSHOT" from the main menu DS81 will prompt
+ for a filename (only up to 8 alphabetical characters). Once entered
+ the snapshot will be saved in the directory ZX81SNAP with an automatically
+ added .D81 extension. If this save fails, an attempt is made to save the
+ snapshot in the root directory of the device.
+
+ On selecting to load a memory snapshot a file selector is displayed. On
+ selecting one of the snapshots it will be instantly loaded.
+
+ Note that along with the machine's state the currently configured keypad
+ mappings are saved in the snapshot and restored when loaded.
