OS: DOS (will run under OS/2 and Windows 9x as well).
The 64Dmon is a disk monitor/editor for .D64 files. As the result of a close co-operation between Therion (Nocturnal Productions) and me this program includes a highly sophisticated 65(C)02 disassembler. No need to explain what a disk monitor/editor does as it's quite obvious. So go ahead and explore with the 64Dmon.

Feature list:

    - 65(C)02 disassembler.
    - 4DOS AutoDetection and DESCRIPT.ION feature.
    - Advanced step functions during edit.
    - Automatic detection of screen length (largest will be default).
    - Automatic floppy scan (On/Off).
    - Combined hex- and character dump/editor.
    - Detailed image information during file selection and editing.
    - DOS Shell.
    - Extraction of files (to .PRG-files) for import in C64S.
    - Image selector.
    - Online help on F1.
    - And much more....
