    • Support DOS order, ProDOS order, and nibblized 2MG floppy images.
  2. WOZ v1 Images (.woz)

    • Support loading original WOZ v1 bitstream images in addition to the currently supported WOZ v2 format.
  3. 13-Sector Disk Images (.dsk)

    • Support early 13-sector Apple II disk images (~113.75 KB / 116 KB) used by DOS 3.1 and DOS 3.2 software.
