# d2-dedicated-server: reconstructing a Diablo II realm and game-server stack

> d2-dedicated-server rebuilds a self-hosted Diablo II realm and headless game-server stack. Its Zig services handle Battle.net-style login, character and game operations, while an ingress reads the game's GAMELOGON token to route connections. A separate native variant maps the 1.14d macOS Mach-O game image onto i386 Linux.

- **Prerequisites:** Redis and PostgreSQL provide runtime coordination and persistent realm storage.
- **Limits:** The native variant's dry run can inspect its load path on other hosts, but execution requires i386 Linux.
- **License:** MIT license.
