Open Source BSD Disassemblers

The "Open On-Chip Debugger" provides JTAG/SWD access from GDB (or directly with TCL scripts) to processors with ARM and MIPS based cores. See website for full list of supported targets.

A disassembler for the linux platform. Currently this supports x86 ELF files assumed to be written in C and output to intel- syntax assembly language; however the design is modular and replacements for any of these can be written.

Creates highly optimized Animated PNG files from PNG/TGA image sequences. CLI versions available for all major OSes. GUI versions for Windows and macOS. Also, APNG Disassembler can be found at http://sourceforge.net/projects/apngdis

Integrated Development Environment for some microcontrollers based on 8051(e.g. AT89S8253). Supported languages are Assembly and C. It has its own simulator, assembler, editor and many other tools. See the project web site for more details and the newest updates.

The decompiler is not limited to any particular target architecture, operating system, or executable file format. ELF, PE, Mach-O, COFF, AR (archive), Intel HEX, and raw machine code supported. 32-bit: Intel x86, ARM, MIPS, PIC32, and PowerPC 64-bit: x86-64 supported. Demangling of symbols from C++ binaries (GCC, MSVC, Borland). Reconstruction of functions, types, and high-level constructs. Output in two high-level languages: C and a Python-like language. Generation of call graphs, control-flow graphs, and various statistics. Detection and reconstruction of C++ class hierarchies (RTTI, vtables). Signature-based removal of statically linked library code. Static analysis of executable files with detailed information. We currently support Windows (7 or later), Linux, macOS, and (experimentally) FreeBSD. An installed version of RetDec requires approximately 5 to 6 GB of free disk space.

iced is a powerful and feature-rich disassembly and assembly library for x86 and x64 architectures, designed to provide accurate decoding, encoding, and formatting of machine instructions. It supports multiple programming languages, including C#, Rust, and Python, making it accessible to a wide range of developers. The library offers both disassembly and assembly capabilities, allowing users to convert between machine code and human-readable instructions in both directions. It includes advanced features such as instruction formatting, symbol resolution, and customizable output, enabling precise control over how code is represented. iced is optimized for performance and correctness, ensuring reliable results even in complex scenarios. It is commonly used in tools for debugging, reverse engineering, and binary analysis. Overall, iced provides a comprehensive solution for working with low-level machine code in modern software systems.

Udis86 is an easy-to-use minimalistic disassembler library for the x86 and x86-64 instruction set architectures. The primary intent of the design and development of udis86 is to aid software development projects that entail binary code analysis.

This program converts APNG file into a sequence of individual PNG frames. Command-line interface and GUI viersions. Also, APNG Assembler can be found at http://sourceforge.net/projects/apngasm

Z80~Ex is the portable ZiLOG Z80 CPU emulator designed as a library. Goals include : precise opcode emulation (documented & undocumented), exact timings for each opcode (including I/O operations), multiple CPU contexts. disassembler is also included.

A standalone powerpc disassembler written as a wrapper over GNU libopcode library. It accepts the opcode ( in hex or decimal ) as it's argument and spits the disassembled output. Recently, a reference assembler has been added. It takes the instruction in string form and spits the assembled 32-bit opcode.It's not fully tested and may not work always.

PEReaDeR is a disassembler of PE (Portable Executable, also knows as windows executable) file.

lida is a fast feature packed interactive ELF disassembler / code-/cryptoanalyzer based on bastards libdisasm (see bastard project).

JReversePro is a Java Decompiler / Disassembler written in Java. Facility to view the ConstantPool contents is available. AWT, Swing and command-line versions are present.

BEYE (Binary EYE) is a free, portable, advanced file viewer with built-in editor for binary, hexadecimal and disassembler modes. It contains a highlight AVR/Java/i86-AMD64/ARM-XScale/PPC-64 and other disassembler, full preview of MZ,NE,PE,ELF and other.

A open source java card virtual machine implementation. And also some part of the VM code can be used as part of kinds of tools such as javacard bytecode disassembler.

Disassembler for Windows(95-XP), currently supports PE, NE, MZ, COM and "unknown" executable formats. Includes also OS independent console version (but requires x86). Output syntax similar to NASM .

The M6811 Code-Seeking Disassembler is a command-line tool that lets you enter known starting vectors for a given code image for the 6811 micro. It will disassemble the code and follow through branches to assist in the separation of code and data. Its companion Fuzzy Function Analyzer uses DNA Sequence Alignment Algorithms to locate similar code in multiple binaries, facilitating reverse-engineering. Originally written to analyze code from GM automotive engine controllers, but is useful anywhere a 6811 micro is being used. Version 1.0 was written in Borland Pascal in April 1996, and updated to v1.2 in June 1999. It was later rewritten to C++ in July 1999 through Jan 2000. While it's been freely available since its creation, it's being released here as an open-source project so the world can better use it as it sees fit. Version 2.0 is completely reworked in 2014 to compile and run with GCC and STL to make it fully portable and accessible to all computer platforms.

Goal of this project is to make a working Intel 8051 simulator. It covers also some I/O devices like keypad, LCD screen and GUI in Qt.

IMAVR is Atmel AVR 8-bit RISC chip emulator for UNIX. You can run your code before programming to chip. Embedded simple debugger and disassembler. Emulate wide range of AVR chip, wide range of their modules: EEPROM,USART, timers and so on.

Bits and Pieces is an interactive 6502 disassembler.

CLI-Dasm(Common Language Infrastructure - Disassembler). A IL disassembler similar to ILDasm, written in C# so that it may be run on other CLI compliant platforms such as Mono.

Java Decompiler, Disassembler and Bytecode debugger. Decompiler supports Java 5 (e.g. generics, for-each loops etc). Debugger allows user to step through each bytecode and view program state. Contains Swing GUI.

lib5600x is a library implementing Motorola DSP5600x disassembler. It's an ANSI C link library that should be useful for people writing debuggers, memory monitors etc for DSP5600x chips.

DiDasm is a small and fast disassembler, useful for Windows kernel developers. Advantages: - highly portable, has minimal runtime requirements (C runtime); - core libraries do not require any external components; - includes instructions emulator (diana_processor); - has stream oriented design; Supported platforms: i386, amd64 Supported instructions: x586/amd64/FPU/MMX/SSE/SSE2

A collection of ACS tools. It will have an ACS disassembler, because I intend to get a method of decompiling as quickly as possible. After that, there will be: compiler, decompiler, linker and translator, etc...
