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.
The ucsd-psystem-xc project provides a Pascal cross compiler for producing UCSD p-System code files on Posix hosts, such as linux. It also provides some other related tools, such as a disassembler.
zDevStudio is an opensource cross-platform IDE based on Pasmo compiler designed to help coders and retrocoders to develop software for Zilog Z80 8 bit CPU.
Java classfile assembler/disassembler and interactive low-level editor
Java Classfile assembler/disassembler and low-level interactive editor. Allows viewing and manipulation of Java class data both manually and via scripts. Load in a class file, make changes, and then save the result.
dxcut is a library for reading, editing, and writing dex and odex files which contain the class definition and Dalvik bytecode used by the Android operating system. This project includes a disassembler/decompiler, dex optimizer, and hooking utils.
Q Disassembler is a flexible disassembly engine that aims to provide precise information about machine instructions while maintaining OS-independence and performance.
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 .
Flasm is an assembler/disassembler for Flash actionscript bytecode.
Using flasm, script authors may learn how actionscript compiler and Flash Player virtual machine work, and tweak the compiled bytecode in SWF files for performance.
Simple 8085 assembler and disassembler for educational use. The 8085asm generates the map file and intel hex file. It support the directives EQU, ORG, DB, DS and END.
AsmDis - disassembler for x86 Linux ELF executables. AsmDis is a interactive disassembler that allows code and data to be identified. Optionally the output can be used by AsmSrc to generate source files.
A opensource 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.
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.
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.
Disassembler for linux: will try to provide a gui driven tool to disassemble executables. Written in C++, uses gtk libraries for the gui, and will disassemble binaries from a number of OSses.
Decompyle is a python disassembler and decompiler which converts Python byte-code (.pyc or .pyo) back into equivalent Python source. Verification of the produced code (re-compiled) is avaliable as well.
jbytecode is a Java bytecode disassembler/assembler written in Python. Dissasembly code is aligned with Java bytecodes in the class file so modification and re-assembly is always possible, even when class is obfuscated.
VirtuAL3101 provides a series of tools to develop effects using the AL3101 DSP from Alesis. It includes an assembler/disassembler, a simulator, an application generator with its graphical interface and various effects.
JasminParser is a Jasmin (Java Assembler, .j file) compiler based on the Apache BCEL. JasminParser provides a disassembler and an assembler to convert java classes and jasmin files to each other.
