PPCD is very accurate PowerPC ISA (and derivative processors) disassembler. Currently supported models are: Generic-32, Generic-64 and Gekko.
PPCD is free opensource. You can use it in your applications without mention.
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.
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.
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.
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.
Tools for Hobbit-based BeOS machines. These tools will extract files from drive images, extract resources from applications, disassembler for the Hobbit (AT&T CRISP 92010) processor, etc.
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.
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.
MEDDAC is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development the author began in 1979. Monitor Editor Disassembler Decompiler Assembler Compiler
JTools.Ruby is easy way to access Java 2 class-files via scripts written in Ruby language. There are class-file disassembler, assembler and simple Ruby to Java bytecode compiler. The work is at the start point.
The goal of IDA-Pro-Code is to provide support for auditing applications including binary audits through extensions of the IDA Pro disassembler by DataRescue sa/nv and/or HexRays.com.
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.
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.
JEST will be the Java bytecode engineering Swiss-Army Jackhammer.
It will include a disassembler, class browser, obfuscator, optimizer, class editor, and bytecode debugger, and have an intuitive GUI.
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...
