Since ladder season 3 is starting I thought I'd add a release a small maphack with basic features.
It's not going to be as feature complete as d2r-mapview but at least it's something.
Since it's new it's not on blizzard's radar yet.
Click on the releases on the right and download the latest executable. Then launch D2R and then launch the executable afterwards.
Note: This DOES NOT NEED old d2lod. Instead it will reveal the normal automap you get in game. This is a standalone executable.
If you find the map isn't showing, try uninstalling and reinstalling D2R. Otherwise ask in the discord for help.
