MAME is a vintage hardware emulation platform designed to recreate the circuitry of arcade games, computers, and consoles to run original software on modern devices. It functions as a retro gaming preservation framework for managing, verifying, and archiving ROM sets and disk images to ensure long-term software accessibility. The project features a system debugging tool for inspecting emulated memory, CPU registers, and execution flow via breakpoints and disassembly. It also includes a Lua-based automation layer that exposes core system state and hardware controls for custom behavior and anal

This is the original C source code for the Quake game engine, a landmark first-person shooter engine from the 1990s. It is a retro game engine that renders 3D environments and processes player input in real time using CPU-based software rendering rather than GPU acceleration. The engine supports networked multiplayer gameplay over LAN or internet connections and is designed to be moddable, allowing users to create and run custom game modifications and levels. The engine's architecture includes a Binary Space Partition tree for efficient world geometry organization and visibility determination

该存储库包含一款单人第一人称射击动作游戏的 C++ 游戏源代码。它是 Id Tech 4 引擎的软件实现，专为 3D 渲染而设计，重点在于实时统一光照和几何体。 该项目支持修改核心引擎逻辑和渲染系统。它可作为经典游戏引擎修改、第一人称射击游戏开发和复古游戏保存的资源。 该引擎利用统一着色器流水线和模板阴影体（stencil shadow volumes）进行光照效果处理，并结合 BSP 树空间分区进行可见性剔除和碰撞检测。它采用基于组件的实体系统来管理游戏对象。

Quake-2 is a game engine designed for the development of first-person shooters and the rendering of three-dimensional environments. It provides the core framework for processing real-time physics and player input within interactive 3D spaces. The engine supports software extensibility, allowing for the direct modification of source code to change gameplay mechanics and engine behaviors. This makes it a resource for retro game engineering and the study of early 3D development techniques. Its technical capabilities include vertex-based software rendering, BSP-tree spatial partitioning, and PVS

Renderer is a low-level software graphics engine implemented in standard C for educational and experimental real-time computer graphics. It functions as a CPU rasterizer that computes vertex transformations, clipping, texturing, and lighting entirely through software computation without requiring hardware acceleration. The software includes a geometry pipeline supporting depth and alpha testing, geometry clipping and culling, and perspective-correct attribute interpolation. Its lighting and shading subsystem provides advanced physical simulation including metallic-roughness and specular-gloss
