notes: |
  GBA emulator by Philippe Daouadi (2009-2011), libretro port by
  Hans-Kristian Arntzen. HLE BIOS in ameteor/source/bios.cpp handles
  SWI calls via Cpu::SoftwareInterrupt() when HasBios() is false
  (ameteor/source/cpu.cpp:245-311). The libretro port never calls
  LoadBios() and never queries RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY.
  Standalone frontends (GTK, text) support optional real BIOS loading.

    note: |
      Full HLE BIOS. The libretro port never loads an external BIOS file.
      Cpu::SoftwareInterrupt() checks HasBios() — if false (always in
      libretro), SWI calls are routed to C++ reimplementations.
