# QEMU (Quick Emulator) libretro core, based on QEMU 9.0.50.
# Builds 17 targets: aarch64, alpha, arm, i386, m68k, mips(el), mips64(el),
# ppc, ppc64, riscv32, riscv64, s390x, sparc, sparc64, x86_64.
# Opens .iso, .img, .qcow, .qcow2 or custom .qemu_cmd_line for any architecture.
# Default architecture is x86_64 when loading .iso/.img/.qcow directly.
#
# All BIOS/firmware files are loaded from {retroarch_system_dir}/qemu/
# via qemu_add_data_dir(system_dir + "/qemu") in ui/libretro.c:659-660.
# QEMU resolves firmware by name through its data directory search path.
# No hash/size validation is performed on any firmware file.
#
# .info declares firmware_count=0. All firmware is loaded by QEMU's internal
# machine/device code, not declared in the .info.

notes:
  bios_directory: >
    All files go in {retroarch_system_dir}/qemu/. The libretro core adds
    this path via qemu_add_data_dir() in ui/libretro.c:659-660.
  default_usage: >
    For typical x86/x86_64 usage (loading .iso/.img/.qcow files directly),
    only bios.bin (or bios-256k.bin) and vgabios.bin are strictly needed.
    Other VGA BIOS variants are loaded depending on the emulated GPU.
    PXE/EFI ROMs are only needed for network booting.
  multi_arch: >
    The libretro build targets 17 architectures. Non-x86 firmware
    is only needed when using .qemu_cmd_line files that invoke a different
    qemu-system-* binary (e.g. qemu-system-ppc for MacOS 9).
  edk2: >
    EDK2 UEFI firmware is shipped as bz2-compressed blobs in pc-bios/. These
    provide UEFI boot for x86, ARM, and RISC-V machine types. Users specify
    them via -bios or pflash in .qemu_cmd_line files.
  experimental: "This core is marked is_experimental=true in its .info file."
  version: "Based on QEMU 9.0.50 (io12/qemu-libretro)"
