notes: |
  An Amstrad PCW 8256 and 8512 core cut out of ZEsarUX 13.0, with every
  other machine removed. The major and minor numbers of library_version are
  the ZEsarUX release, the last one the port's own.
  ref: src/pin.json:1-8, src/libretro/libretro.c:246-255

  The PCW boot ROM sequence is replaced by a bootstrap written in C, which
  loads the boot sector of the inserted disc. When the disc is not bootable,
  the OpenPCW-OS helper disc embedded in the core is mounted instead and
  starts CP/M. Neither reads a file.

       src/dsk.c:161-166, src/dsk.c:382-385

  The core never asks the frontend for its system directory. The only files
  it opens are the content discs.
