notes: |
  bsnes C++98 is bsnes v085 downgraded to C++98 for old compilers.
  Performance profile only. is_experimental=true.

  Firmware loading differs from newer bsnes versions:
  - NEC DSP (dsp1/2/3/4) and Hitachi DSP (cx4) firmware loaded from
    the SAME DIRECTORY as the ROM, not from system_dir.
  - Path: dir(interface->path(Slot::Base, ".dsp")) + firmware_name
    ref: snes/cartridge/markup.cpp:231
  - interface->path() returns basename + hint
    ref: snes/libretro/libretro.cpp path() method
  - Firmware name comes from the game's XML/BML markup (root["firmware"])
    NOT fixed names like dsp1.program.rom
  - Files are COMBINED (program+data in one file), not split
    ref: snes/cartridge/markup.cpp:243-244 reads promsize*3 + dromsize*2

  .info has firmware_count=0 because firmware is loaded from ROM dir,
  not from system_dir — RetroArch can't pre-populate them.

  The core warns "NEC DSP firmware X is missing" if not found but
  continues without the coprocessor (games using it won't work).
