notes: |
  Discrete Integrated Circuit Emulator. Emulates early arcade hardware built
  from discrete logic components with no CPU. Libretro port by Ken Mitton,
  based on upstream DICE by Adam B.

  Games load as MAME-style ZIP archives matched by CRC32 per ROM chip
  (chips/rom.cpp:41-218). ROM-less games (Pong, Breakout, etc.) use .dmy
  dummy launcher files. The system directory is retrieved but never used
  for file loading (libretro.cpp:60-62).
