D2SLib

Simple C# library for reading and writing Diablo 2 saves. Supports version 1.10 through Diablo II: Resurrected (1.15). Supports reading both d2s (player saves) and d2i (shared stash) files.

Usage

Use Nuget to add D2SLib to your project.

using D2SLib;
using D2SLib.Model.Save;

....
//read a save
D2S character = Core.ReadD2S(File.ReadAllBytes(@"Resources\D2S\1.15\DannyIsGreat.d2s"));

//outputs: DannyIsGreat
Console.WriteLine(character.Name);

//convert 1.10-1.114d save to d2r 1.15
character.Header.Version = 0x61;

 //set all skills to have 20 points
character.ClassSkills.Skills.ForEach(skill => skill.Points = 20);

//add lvl 31 conviction arua to the first statlist on the first item in your chars inventory
character.PlayerItemList.Items[0].StatLists[0].Stats.Add(new ItemStat { Stat = "item_aura", Param = 123, Value = 31 });

//write save
File.WriteAllBytes(Environment.ExpandEnvironmentVariables($"%userprofile%/Saved Games/Diablo II Resurrected Tech Alpha/{character.Name}.d2s"), Core.WriteD2S(character));

How to seed the library with your own TXT files

TXT txt = new TXT();
txt.ItemStatCostTXT = ItemStatCostTXT.Read(@"ItemStatCost.txt");
txt.ItemsTXT.ArmorTXT = ArmorTXT.Read(@"Armor.txt");
txt.ItemsTXT.WeaponsTXT = WeaponsTXT.Read(@"Weapons.txt");
txt.ItemsTXT.MiscTXT = MiscTXT.Read(@"Misc.txt");
Core.TXT = txt;
D2S character = Core.ReadD2S(File.ReadAllBytes(@"DannyIsGreat.d2s"));
