Blaster Master was one of my favourite games, one of the few non-Nintendo-published/developed games I own. I love that vehicular retraversal was done so well. It's one of the more deeper and challenging NES games...and as usual, Sunsoft puts out incredible NES graphics.
My brother made the wrap-around maps currently on the site. He didn't use an editor but he soon found that the individual Areas actually wrap around in a 2048 x 2048 space, which explains some of the shortcuts back to the Gate in certain Areas (2, 6, and 7 come to mind). I really like these wrap-around maps, but I wonder if an editor (I know one exists) could recreate the maps really easy.
But your maps...wow! With all Areas mapped (including both versions of Area 4, apparently), as well as all the dungeon-type areas, I'll definitely put them up, but then I have to figure out of there's any worth of having my brother's maps here anymore...
