This article describes the creation of a Hex-Rays-like decompiler for an exotic programming language used in the game “Pathologic”. You will learn how cross-compilation works and master the basics of the compilation theory so that you can write such a decompiler yourself.

Today, I will show you how to crack the game engine to find out how its scripts operate. Furthermore, you will write your own decompiler for an unknown programming language!
