Open Source Assemblers

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.

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.

BASM is a user friendly and easy to use assembler for The Basic Computer, capable of creating the object, list and hex file and giving detailed error reports. It's more of academic use for students who wish to understand how does The Basic Computer actually work. Alongside this assembler, soon a simulator will also be available at BASM's SourceForge page.

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.

Machine Instructions Engine is the engine that can disassemble instruction, disassemble its length, assemble instructions and emulate device(processor). The engine will support Intel and AMD instructions. For now length disassembling and Intel instructions only are supported. This project is intended to be as separate library. Also you can use sources to use this engine in your projects directly. This is my first public project so if you send me advices about how to improve this project, notice about bugs, or ask for additional info i'll appreciate it. Current version is 0.3.99.0

Project-Sparroh is a hobby operating system project. Goal is to write an OS from scratch for the purposes of learning how they work and for fun. An assembler and high level language cross-compiler will also be written first and used to build the OS.

Q Disassembler is a flexible disassembly engine that aims to provide precise information about machine instructions while maintaining OS-independence and performance.

Reblok build an Abstract Syntax Tree (AST) from a python bytecode (typically found in .pyc files).

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.

nsL is a new C-like programming language for writing NSIS installation wizards (http://nsis.sourceforge.net). The nsL assembler takes nsL code and translates it into original NSIS script which can then be compiled.
