A portable C reimplementation of the classic ZX Spectrum isometric 3D game 'The Great Escape'.
The Great Escape in C is a complete reimplementation of the classic 1986 ZX Spectrum isometric 3D game, translated from its original Z80 assembly language into portable C code. It allows the game to run natively on modern operating systems like macOS, Windows, and RISC OS without needing a ZX Spectrum emulator, while fixing some original bugs and preserving the exact gameplay.
Retro gaming enthusiasts, developers interested in reverse engineering classic games, and programmers looking to study Z80 assembly to C translation techniques or port classic games to other platforms.
It provides an accurate, emulator-free way to experience the classic game on modern systems, serves as an educational resource for understanding vintage game logic, and offers a portable codebase for further ports to other retro or contemporary hardware.

Accurately reimplements the original ZX Spectrum game logic and graphics, preserving the exact gameplay as intended in 1986, including data tables and isometric 3D rendering.
Written in portable C, it builds on macOS, Windows, RISC OS, web via emscripten, and even retro systems like BBC Micro, enabling native play without emulators.
Provides deep insights into Z80 assembly translation to C, with analysis of performance metrics and coding techniques from the original game.
Addresses some bugs from the original release, enhancing stability while maintaining the core experience, as mentioned in the project goals.
Some ports, like Windows, lack sound and UI polish, and the SDL build has broken timing, making certain versions less feature-complete or reliable.
Building for platforms like RISC OS requires specific toolchains like GCCSDK and is described as challenging, indicating a steep setup curve for non-standard systems.
Focuses on accuracy over enhancements, so it lacks modern conveniences such as save states, graphical upgrades, or broad controller support beyond original key mappings.
