Abdessamad Derraz de1940d57c feat: hle_fallback on 39 emulator profiles (266 entries)
Batch analysis of all 273 profiles to identify HLE/embedded
fallbacks. Added hle_fallback: true where the core has verified
software replacement for missing BIOS files:

- Embedded ROMs: vice (102), ep128emu (22), fuse (18), frodo (4)
- HLE BIOS: bsnes* (33 across 3 profiles), puae (9 AROS),
  noods (4), melonds* (6 FreeBIOS), flycast (3 reios)
- Open-source replacements: sameboy (8), pokemini (1), gpsp (1)
- Built-in fallbacks: np2kai (7), atari800 (6 Altirra),
  picodrive (3), quasi88 (4), gambatte (2)

Conservative: only added where notes or source code confirm HLE.
Skipped 50+ profiles where files are optional alternatives, not
HLE replaceable (neocd, opera, kronos, pcem, etc.)

notes: |
Citra 2018 is a 2018 snapshot of the Citra 3DS emulator.
Older than current Azahar/Citra — fewer firmware files.
Data dir: citra-emu (not azahar-emu).
ref: src/common/common_paths.h:24
Uses RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY.
ref: src/citra_libretro/environment.cpp:107
Loads from sysdata/:
aes_keys.txt (not keys.txt like current Citra)
shared_font.bin
ref: src/core/hw/aes/key.cpp:72-73, src/core/hle/service/apt/apt.cpp:174
Does NOT load (added in later versions):
boot9.bin, sector0x96.bin, seeddb.bin, otp.bin,
movable.sed, SecureInfo_A, LocalFriendCodeSeed_B
firmware_count absent in .info (= 0). Files are optional (HLE).
