If yours isnt a clone then there is more images out there than you would know what to do with lol.
Gemini 4.7 was released in january.
Ozone -January,
Niablo -January
Merlin2-Excalibur - January,
LT6 The Sixth Sense DM800 - January,
EDG-Nemesis 1.0 - December
The above list is compiled from images that I know have been patched for the clones. But this indicates that these images and more have recently been officially released for the original DM800. Like I said there will be tons more ontop of that as most images don't get patched to work with the clones.
That should give you a start to be going on with.
