Since that's using the Intellivision Productions overlay (elements anyway), I would prefer not to share my personal version. But it's easy to create. Someone over at Atariage took high-res scan of the two AD&D games overlays. Just bring them into GIMP and re-arrange the 3-across as 4-across and then you can use this mapping:
// -----------------------------------------------------------------
// AD&D Cloudy Mountain Overlay for Nintellivision
