JC64dis (next generation C64 disassembler) is an iterative disassembler for MUS, SID and PRG file of Commodore 64.

It works with 3 area:

  1. Memory area (from $0000 to $FFFF)
  2. Preview of source
  3. Source

You can formatting the source using the commands in a way to produce a source like if you were writing it in a text editor.

Labels and some comments are created automatically, but you can customize all.

In the video you can see a true session of usage where a binary is reverse engineered into a source that can be compiled again.

Binary are in jar (java) or specific for Windows (win32 o win64)
