notes: |
  Frozen snapshot of Snes9x 1.52.4, rewritten in C with optimizations
  for PS3 (originally called SNES9x Next).
  SPC700 IPL ROM (64 bytes) embedded in src/apu.c:3442 as APUROM[64].
  DSP-1 ROM data (1024 x uint16) embedded in src/dsp.c:219 as DSP1ROM[1024].
  All coprocessors (DSP-1/2/3/4, CX4, ST010/011/018, SuperFX, SPC7110,
  SA-1, S-DD1, S-RTC, OBC-1) are pure HLE.
  Sufami Turbo support disabled: LoadSufamiTurbo in src/memmap.c is behind
  #if SNES_SUPPORT_MULTI_CART which defaults to 0 and is never enabled in
  any Makefile. retro_load_game_special returns false.
  Upstream snes9x 1.52 supports Sufami Turbo (loads STBIOS.bin).

    notes: |
      Loaded when a BS game is auto-detected (is_bsx checks ROM header at
      0x7FC0/0xFFC0). Without this file, BSX.bootup is set to FALSE and
      BIOSROM is zeroed. BS games still load but lack the boot menu.
