LumpStich

LumpStich is a deobfuscation tool made by Rim032. Maps are often given anti-decompile protection to prevent players from decompiling, studying and sometimes even playing those maps. This program removes such lump protection and restores a map to it's original state. This tool is intended to work with Garry's Mod and Half-Life 2 maps.

Note:LumpStich has only been tested with version 19 and 20 maps.

How It Works

A protected BSP file and it's acompanying LMP file are carefully stiched together at a specific binary offset to reform an unobstructed .BSP. This ubobstrcuted .BSP can then easily be decompiled and played while the protected .BSP cannot be decompiled, lacks entities and may even crash your game.
