How do I set up UnderworldGodot with my GOG Ultima Underworld files?

Extract the game.gog file using a tool like 7-Zip, then point the uwsettings.json configuration to the folder containing the .exe. The README provides a sample JSON format and instructions for path setup.

UnderworldGodot vs other Ultima Underworld engine recreations – which is better?

UnderworldGodot supercedes the Unity-based project with a more accurate Godot engine recreation, but it's pre-alpha and missing features. Older projects like Underworld Adventures might be more stable but less actively developed for modern engines.

Can I save my game progress in UnderworldGodot?

No, saving is currently missing as listed in the 'Whats missing' section. It can load original save files but cannot create new saves, limiting it to a map viewer or debug tool.

How to compile UnderworldGodot from source in Godot?

Clone the repository, install .Net 9.0 and Godot 4.3.0, set up the uwsettings.json file, open the project in Godot, run the build process, and execute from LaunchScene.tscn as per the 'Getting Started' guide.

What major features are still missing from UnderworldGodot?

Key missing features include saving, foley sound effects, sprite transparencies, animated dragon UI, endgame screens, and swimming mechanics, as detailed in the 'Whats missing' list.

Is UnderworldGodot suitable for learning Godot game development?

Yes, it's a valuable resource for understanding retro game engine recreation and Godot implementation, with comprehensive code on RPG systems, but the niche focus on Ultima Underworld may limit broader applicability.

What is UnderworldGodot?

UnderworldGodot is a from-scratch recreation of the game engines for the classic dungeon-crawling RPGs Ultima Underworld and Ultima Underworld 2. It faithfully rebuilds the original gameplay experience—including map loading, NPC interactions, combat, and spellcasting—within the modern Godot game engine. This project serves as a preservation effort and a technical reference for these influential titles.

Target Audience

Game developers, preservationists, and hobbyists interested in retro game engine recreation, specifically those studying or modding the Ultima Underworld series. It is also for technical researchers looking for a reference implementation of these games' mechanics.

Value Proposition

Developers choose this project for its 'vanilla-plus' philosophy, prioritizing accuracy to the original games' look, feel, and mechanics over modernization. It offers a comprehensive, open-source reference built on the accessible Godot engine, superceding previous efforts like the Unity-based project.

Zelda3

Zelda3 is a complete reimplementation of the classic SNES game *The Legend of Zelda: A Link to the Past* in C, comprising approximately 70-80k lines of code. It faithfully replicates the original game's logic and behavior while enabling verification through side-by-side execution with the original machine code. This project makes the game accessible on modern platforms and allows for community-driven improvements and modifications. ## Key Features - **Complete Game Reimplementation** — All parts of the original game are recreated in C, making it playable from start to end. - **Verification System** — Can run original machine code alongside the C implementation to compare RAM states each frame for accuracy. - **Modern Enhancements** — Adds features like pixel shaders, 16:9/16:10 aspect ratios, higher-quality world maps, and MSU audio track support. - **Quality-of-Life Improvements** — Includes a secondary item slot on button X, item switching with L/R keys, and snapshot-based replay functionality. - **Cross-Platform Support** — Compiles and runs on Windows, Linux, macOS, and even Nintendo Switch with appropriate toolchains. ## Philosophy The project prioritizes accuracy and verification, ensuring the C implementation behaves identically to the original SNES game while thoughtfully adding modern features that enhance the experience without compromising authenticity.
