Platform details

• gba:

  • bios_size: 16384
  • hle_bios: yes
  • source_ref: ameteor/source/bios.cpp (emulator code, libretro port), ameteor/source/cpu.cpp:245-311
  • 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.

Technical 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.

No BIOS or firmware files required.
