Open Source WINE Assemblers

The M6811 Code-Seeking Disassembler is a command-line tool that lets you enter known starting vectors for a given code image for the 6811 micro. It will disassemble the code and follow through branches to assist in the separation of code and data. Its companion Fuzzy Function Analyzer uses DNA Sequence Alignment Algorithms to locate similar code in multiple binaries, facilitating reverse-engineering. Originally written to analyze code from GM automotive engine controllers, but is useful anywhere a 6811 micro is being used. Version 1.0 was written in Borland Pascal in April 1996, and updated to v1.2 in June 1999. It was later rewritten to C++ in July 1999 through Jan 2000. While it's been freely available since its creation, it's being released here as an open-source project so the world can better use it as it sees fit. Version 2.0 is completely reworked in 2014 to compile and run with GCC and STL to make it fully portable and accessible to all computer platforms.

GenDasm is a Generic Code-Seeking Diassembler engine. It allows you to enter known starting vectors for a given code image for the micro. It will disassemble the code and follow through branches to assist in the separation of code and data. Its included Fuzzy Function Analyzer companion uses a DNA Sequence Alignment Algorithm to locate similar code in multiple binaries to facilitate reverse-engineering and/or code recovery. The original purpose of the Fuzzy Function Analyzer was to assist in code recovery where the source code for the current binaries got lost, yet the source code for an old binary was retained. The Fuzzy Function Analyzer allows you to match up known functions between the two binaries so you can concentrate on disassembling and reverse engineering the parts that are different and recover the code for the current binary that got lost.
