notes: |
  Frozen snapshot of Final Burn Alpha v0.2.97.28 (circa 2012), CPS-2 only.
  Exists for RAM-constrained platforms (3DS, embedded).

  CPS-2 has no system BIOS. Each game's ROM set is self-contained:
  68000 program ROMs + Z80 sound program + GFX ROMs + QSound samples.
  Zero BRF_BIOS entries in entire codebase. No BRF_OPT entries either
  (PLD references stripped from this CPS-2-only build).

  QSound emulated in software (qs_c.c). No external QSound DSP ROM needed.
  All audio data loaded from game ROM ZIP.

  ROMs loaded from content directory (g_rom_dir, libretro.cpp:969).
  g_system_dir used only for hiscore.dat (hiscore.c:228-232).

  Hiscore support gated by fba2012cps2_hiscores core option
  (libretro.cpp:561-563) and per-game BDF_HISCORE_SUPPORTED flag.
