IDA

The Interactive DisAssembler (IDA) is a disassembler with debugging functions that supports a huge variety of CPU architectures and file formats. Originally a shareware OS/2 application that disassembled native and DOS executable only but later gained a DOS extended version and a MS Windows console port. The current version has bee re-written from scratch and now supports MS Windows, MacOS X and Linux only, and has replaced the internal C like macro language with the use of Python.

Originally released as shareware and published from Saint-Petersburg in Russia, but the author and his company have since relocated to Belgium.
