Simple 68HC11 disassembler.

This project is built with CMake. After downloading the source code, navigate to the source directory and run:

mkdir build
cd build
cmake ..
make

An executable called dis68hc11 will appear inside the build directory.

This is a command line utility. It takes an EPROM file as argument. The address of the last byte of the EPROM image is always considered to be 0xffff, with the first address adjusted to the size of the image. By default, the disassembler reads the initial program counter from addresses 0xfffe and 0xffff (the INIT interrupt). Starting from that address, it disassembles the program until it reaches an unknown opcode. This can either be a unimplemented opcode, or non-program data. To disassemble specific subroutines, use the -s argument to set a start address instead of reading it from 0xfffe and 0xffff.

Not all opcodes are implemented yet, expecially rarely-used multi-byte opcodes.
