  Mednafen v0.9.36 GBA module (libretro.cpp:73), whose GBA code derives

    note: >
      Read only when the gba_hle core option is disabled, a setting read at
      startup only. It is enabled by default and the core then uses its
      built-in HLE BIOS. A file of any size other than 16384 bytes is ignored
      and the core falls back to HLE.
