REDasm is a cross-platform disassembler and binary analysis tool for examining compiled programs. It combines a native Qt interface with a separate analysis engine, giving reverse engineers an interactive environment without tying the underlying analysis facilities to the graphical frontend.
The architecture is extensible, with processor support and executable loaders implemented as plugins. REDasm also gives unusual attention to retro and legacy executable formats alongside contemporary binaries, making it relevant for software preservation as well as conventional reverse engineering.
This is free and open source software.
Key Features
- Interactive disassembly listing with renaming, comments and typed data.
- Function-level control flow graphs synchronized with the listing.
- Navigable cross-references for code and data.
- Automatic detection of ASCII, UTF-16 and Latin-1 strings.
- Type system supporting structs, unions, enums and typedefs.
- Integrated hex viewer.
- Panels for segments, imports, exports, symbols, strings and problems.
- Save and restore analysis projects including annotations and renames.
- Patch binaries and export analysis data.
- Architecture-neutral intermediate language for analysis and lifting.
- Support for PE, ELF and several legacy and console formats.
- Processor support including x86, x86-64, ARM, AArch64, MIPS, Z80 and MOS 6502.
- Analyzers for Visual Basic binaries and Microsoft runtime information.
- Light and dark themes.
- Analysis engine can be used independently of the GUI.
