2. Append "/gba_bios.bin"
3. load_bios() reads 0x4000 (16 KB) into bios_rom[]
4. Sanity check: bios_rom[0] must be 0x18 (ARM branch opcode)
5. On failure, memcpy open_gba_bios_rom[] as fallback
The official BIOS improves compatibility for a few games that rely on
precise SWI behavior or BIOS checksum verification. The built-in BIOS
works for the vast majority of the GBA library.

The built-in BIOS (open_gba_bios_rom, 16 KB) is an open-source
reimplementation compiled from bios/source/. It implements most
SWI calls (SoftReset, RegisterRamReset, Halt, VBlankIntrWait,
arithmetic, decompression, sound, multiboot).
Validation is minimal: load_bios() in gba_memory.c reads exactly
0x4000 bytes. The libretro frontend checks bios_rom[0] == 0x18
(ARM branch instruction at reset vector) to reject garbage files.
No hash or checksum verification is performed.
No hash or checksum verification is performed. The only check
is bios_rom[0] == 0x18 (ARM branch at reset vector).
The bios_type enum (main.h:56-61) defines three modes:
auto_detect - try official first, fall back to built-in
