ImHex creator publishes guide to reverse-engineering FEZ's binary save format
The developer behind the ImHex hex editor wrote a tutorial demonstrating how to reverse-engineer an undocumented binary file format, using the 2012 game FEZ's save file as the example. The walkthrough shows how to move from raw hex bytes to a complete structure definition written in ImHex's Pattern Language, a feature available on the free, open-source, cross-platform tool.
