+## HD image
+
+In the directory [HDimage](HDimage/), you can find a 4MB z80pack compatible HD image conaining all the game files (minimal file count).
+All games are on user area 0, except Wanderer, which uses a lot of data files - Wanderer is placed in user area 1.
+This HD image file should be usable e.g. on the IMSAI 8080 clone or any other z80pack powered emulation.
