Well i've been gone for few years, i'm sorry ! But i'm now back and offering you a way to reveal the map as good old times!
If you like it, i may release more hack, remember, i never released any bad file, i analyse, check, use them myself before releasing anything so far.
Just remember to never download anything posted in comments, because i can't vouch those files.
Simple map revealer for Diablo II v1.14 by FIRK
How to use:
1) Select your Diablo II window from list
2) Be sure that you are in game with your character standing still.
2) Press "REVEAL" button.
3) Current act will be revealed.
If Diablo II window not shows in list, try to run as administrator.
It unloads immediately after revealing as usual.
