Select the character save file (.d2s), commonly found under C:\Users\(your user name)\Saved Games\Diablo II Resurrected. The character save files consist of a .d2s, .map, .key, and .ctl file, which all share the same name. You can either edit and overwrite the .d2s file or replace it with another one.
This tool allows you to load, edit, and generate .d2s files.
