Area 51 (2005) Source Code

Welcome to the unofficial release of the Area 51 (2005) video game source code! This project aims to resurrect and preserve a piece of early 2000s video game history for enthusiasts, historians, and developers alike. Below is a brief overview of the source code details, its origin, and guidance on how the community can help bring this game into the modern era.

How to Contribute

The main goal is to get the source code into a buildable state on modern systems. Whether you're interested in game development, historical preservation, or simply a fan of Area 51, here's how you can help:

Building the Project: Assistance is needed to compile and run the game on contemporary hardware. If you have experience with game development, legacy systems, or cross-platform development, your expertise is invaluable.
Documentation and Research: Insights into the original development environment, including compilers, libraries, and tools, would greatly assist the restoration effort.
Debugging and Porting: Once buildable, the project will require debugging and potentially porting to newer platforms to reach a wider audience.
Forking and contributing: Make changes in your forks, and submit a pull request with your updates.

PC Code issues

Model Format Compatibility (rigidgeom, skingeom): The most critical issue at present is the incompatibility of the PC build with the new retail model formats. The engine does not currently support updated rigidgeom and skingeom model structures used in the latest retail version.

Update: GEOM V41 may be partially restored — further testing required to confirm stability.

Audio System Malfunctions: The Miles Sound System 6 implementation is broken — MP3 decoding fails, and both Bink audio playback and world ambient audio systems are non-functional.

Update: Miles6 may be partially restored — further testing required to confirm stability.

Multiplayer & Network Stack Failure: The network layer is completely broken. Multiplayer functionality is non-operational, and several systems tied to single-player logic are also affected.

Update: Single-player logic may be partially restored — further testing required to confirm stability.

Console UI (Incomplete Interface): The PC version is currently using the console UI. This results in:

Missing PC-specific settings (graphics, keybindings, etc.)
Redundant console-only interface logic included in the build, which clutters the UI codebase.

Save System Not Implemented: The save system has not been implemented for the PC version.

Update: Save system logic may be recreated — further testing required to confirm stability.

PC Renderer Not Implemented: There is no functional rendering backend for the PC version — rendering code is almost not implemented. The game cannot post-process, lighting and etc.

Building PC Code

The following prerequisites are required to build the source tree for PC:

Visual Studio .Net 2003
Xbox SDK - 5849
You'll need to create an environment variable called X and S that points to the important library directions of the source tree. For example, if the source tree is located at 'D:\area51-pc' the X environment variable should point to 'D:\area51-pc\xCore'. the S environment variable should point to 'D:\area51-pc\Support'
Put game assets to 'C:\GameData\A51\Release\PC\DVD'
XtremeToolkit 4100 (FOR UI TOOLS) | Install it from "xCore\3rdParty\CodeJock"
