notes: |
  Frozen snapshot of bsnes v085 downgraded to C++98 for old compilers (PS3).
  Performance profile only. is_experimental=true.

  NEC DSP and Hitachi DSP firmware loaded from the ROM directory, not
  system_dir. Path: dir(interface->path(Slot::Base, ".dsp")) + firmware_name
  from game XML markup. interface->path() returns ROM basename + hint.
  ref: snes/cartridge/markup.cpp parse_markup_necdsp, parse_markup_hitachidsp
  ref: snes/libretro/libretro.cpp Interface::path()

  RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY is never called.
  No file I/O targets system_dir anywhere in the codebase.

  Core continues without DSP firmware but coprocessor games won't function.

exclusion_note: >
  firmware_count=0 in .info is correct. DSP firmware (NEC uPD7725/uPD96050,
  Hitachi CX4) is loaded from the ROM directory via game XML markup, not from
  system_dir. RetroArch cannot pre-populate firmware in the ROM directory.
  Upstream byuu.org is defunct; this libretro port is the preserved v085 code.
