I'm playing on my characters on single player and I want the full map explored. I used the maphack but if I save with it on it doesn't stay on. I was looking for something, an editor or such, that could just make my map full...forever without having to use a program constantly. If anyone can solve my problem, or just has an idea, I'd appreciate the input.

theres none that can do that bud, just download maphack and each time u run d2 just minimize it click on d2map hack and hit instal, its the only way (i think) and it doesnt take that long

Crap, I thought I remember using an editor that did that, but I guess MH aint that complicated. I'll just use that then, Thanks!

all you have to do is explore the whole map (gets good exp for your character too)
then when you save, quit, and go back on another time, the map loads with all the places you previously visited. if you play it once every few days it will stay up there. but if you stop playing 1player for like 1 month then the map resets.
