Reko is a comprehensive toolkit that allows you to dissect binaries and translate them into higher-level languages, whether you are on Windows, Linux, or Mac (it’s coded in .NET).
Its developers have thought of everything, offering a super intuitive graphical interface for novices and a command-line interface for terminal pros who enjoy an old-school approach.
Reko also includes a library that supports a variety of processor architectures (x86, 68k, PowerPC, ARM, MIPS, Z80…), binary file formats (MZ, ELF, AmigaOS Hunk, Classic MacOS…), and operating systems. It can even automatically run decompression scripts written in OllyScript.
Great for understanding how a program works and doing a bit of reverse engineering for fun.
