Diablo 2 Resurrected HolyGrail Tracker based on character save file parsing

Personal project to experiment and learn Rust language. Comments and PRs regarding code style, idioms, efficiency, etc. are welcome!

Reference for *.d2s file parsing is this parser written in JS: https://github.com/dschu012/d2s

• Watch save file for changes
• Check if save file is saved on unidentify item YES
• Parse Unique and Set items
• Save found items (SQLite)
• Minimal GUI
• Create transparent overlay (Qt, Windows specific lib?)
• Stretch goal: Research Modding for coloring already found items when you see them on the ground in the game

I will try to bring https://github.com/krisives/d2s-format up to date here.

Integers are stored in little endian byte order.

Save file version. Current version of the game uses 99. In the future if version changes File Format should be versioned and changes documented.

• <98 is pre D2R
• 98 is version ??
• 99 is current version 1.6.74264

Needs to be re-calculated when editing save file otherwise it will not be valid anymore. Credit for algorithm goes to whoever reverse engineered it.

8-bit field of flags for statuses

Character names are stored as an array of 16 characters which contain a null terminated string padded with 0x00 for the remaining bytes. Characters are stored as 8-bit ASCII, but remember that valid names must follow these rules:

• Must be 2-15 in length
• Must begin with a letter
• May contain up to one hyphen (-) or underscore (_)
