  The libretro port (libretro/flycast, last updated 2025-12-12) is significantly
  behind upstream (flyinghead/flycast). Key divergences:
  - NAOMI 2 has no separate BIOS entry or platform detection; NAOMI 2 games
    run as NAOMI using naomi.zip. Upstream has naomi2.zip with dedicated ROMs.
  - System SP is not supported. Upstream has segasp.zip support.
  - The n2_ prefix for NAOMI 2 flat boot ROMs is dead code (DC_PLATFORM_NAOMI2
    is never assigned to settings.System in the libretro port).
  - Flash search includes legacy names (%flash_wb.bin, %flash.bin, %flash.bin.bin)
    that upstream has removed.
  - NAOMI flat boot ROM search includes epr-21576d.bin fallback not in upstream.
  BIOS file search uses prefix + name pattern. The libretro port appends "dc/"
  to the system directory (libretro.cpp:1866). All files below are relative
  to system_dir/dc/.
  File loading logic: core/hw/flashrom/nvmem.cpp loadFiles() and
  core/hw/naomi/naomi_cart.cpp loadBios().
  The prefix is determined by platform (sb_mem.cpp:32-49):
    Dreamcast   -> dc_
    Dev Unit    -> hkt_
    NAOMI       -> naomi_
    NAOMI 2     -> n2_ (libretro port; upstream uses naomi2_)
