Projects / Dissy


Dissy is a disassembler for multiple architectures. It is implemented as a graphical frontend to objdump. It allows fast navigation through the disassembled code and easy searching for addresses and symbols.

            I've reimplemented Dissy from scratch (and renamed it). The new project can be found on or here at

            I'd suggest all Dissy users to try EmilPRO instead - I won't make any further updates to Dissy.
