notes: |
  Same codebase as Snes9x 2005 built with USE_BLARGG_APU=1 for more accurate audio.
  Frozen snapshot of Snes9x 1.43 via CATSFC (NDS/PSP port by ShadauxCat/Nebuleon).
  SPC700 IPL ROM (64 bytes) embedded in apu_blargg.c:3272 as APUROM[64].
  DSP-1 ROM data (1024 x uint16) embedded in dsp1emu.c:8 as DSP1ROM[1024].
  All coprocessors (DSP-1/2/4, CX4, ST010/011/018, SuperFX, SPC7110, SA-1, OBC-1)
  are pure HLE. The core never calls GET_SYSTEM_DIRECTORY and performs no file I/O
  from the system directory.

exclusion_note: "all coprocessor ROMs embedded in binary; no system_directory access"
