notes: |
  Frozen at bsnes v094. Three build profiles: accuracy (dot-based PPU),
  balanced, performance (scanline PPU). All 3 share the same 18 firmware
  files. Profiles only differ in PPU (sfc/profile-*.hpp), not coprocessors.
  Performance .info is wrong (firmware_count=17, missing cx4.data.rom).
  SPC700 IPL ROM (64 bytes) embedded in target-libretro/libretro.cpp:31.
  No HLE fallback for any coprocessor in v094.
  Firmware loaded from system_dir via file::exists() + mmapstream.
  DSP1 (non-b) names used via embedded database for specific SHA256-matched
  games; DSP1B names used via heuristic fallback for all DSP1/DSP1B games.
  Upstream v094 source is contained within the libretro repo (sfc/, ananke/).
  bsnes-emu/bsnes is the modern rewrite (v115+).
