BrkDown is a desktop disassembler for the IIgs, which can disassemble both 8 and 16 bit source, to give ORCA/M or Merlin 16 compatible source files. BrkDown will disassemble both the data and resource forks. The working files can then be edited with powerful function commands to make file sets that can then be reassembled, and then can finally be output as source files ready for your assembler.
