objdiff
A local diffing tool for decompilation projects that compares object files and highlights assembly differences.
What is objdiff?
objdiff is a local diffing tool specifically designed for decompilation projects. It compares relocatable object files (`.o`) generated from decompiled source code against original target binaries, highlighting differences in assembly output to help developers verify accuracy. The tool automates rebuilding when source files change and supports a wide range of CPU architectures used in gaming consoles and PCs.
Reverse engineers and game modders working on decompilation projects for consoles like GameCube, Wii, N64, PS1, PS2, PSP, Switch, GBA, DS, 3DS, Saturn, Dreamcast, and PC platforms. It's also useful for developers contributing to open-source game reimplementations.
Developers choose objdiff because it automates the manual and error-prone process of comparing assembly output, provides an interactive GUI with features like click-to-highlight and filtering, and integrates directly into project build systems with automatic rebuilds. Its support for multiple architectures and symbol demangling makes it a versatile tool for cross-platform decompilation work.
