'Sup.
Let's see... I think I first found it through word-of-mouth, really. On GameFAQs, there's this thing called the NES FAQ Completion Project (basically getting a guide out for every last NES/Famicom - and now Famicom Disk System - game out there), and at some point they linked to an overworld map of Double Moon Densetsu on here. Having done quite a few maps myself, I figured I'd send those not covered here along since it wasn't as annoying as uploading ~1,000 maps one at a time.
