About

SkiFree is a single-player skiing game created by Chris Pirih and released with Microsoft Entertainment Pack 3 for Windows 3.0 in October 1991, where the player skis down a mountain avoiding obstacles while racing against time or performing stunts. This project reconstructs the source code of the 32-bit version of SkiFree (v1.04) back into C, aiming for byte-for-byte compatibility with the original and buildable with Visual Studio 6. All code and data have been converted to C, though full matching against the original binary is still in progress.

Getting started

Requires the original 32-bit SkiFree executable (its MD5 hash is given for verification); graphics and icon resources are extracted from it with a third-party resource-extraction tool and placed into the project before compiling with Visual Studio 6.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game. Requires the original ski32.exe to extract graphics and icon resources.
