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: |
|
|
bsnes-mercury is bsnes v094 with Mercury optimizations: HLE for DSP
|
|
and Hitachi coprocessors, firmware_appended support, overclocking.
|
|
Three profiles: accuracy, balanced, performance (PPU differs, not firmware).
|
|
.info says performance has 17 fw (no cx4) but the code compiles CX4 LLE
|
|
in all profiles — cx4.data.rom works in performance too. The .info is wrong.
|
|
Core option bsnes_chip_hle (default LLE) controls HLE/LLE at runtime.
|
|
ref: target-libretro/libretro.cpp altImplementation(), "bsnes_chip_hle"
|
|
|
|
Same firmware loading as bsnes2014: system_dir via file::exists +
|
|
mmapstream. No BS-X auto-load from system_dir (subsystem only).
|
|
ref: target-libretro/libretro.cpp:245-254

|
HLE fallback for DSP1/1B/2/4, Hitachi/CX4, ST010.

ref: sfc/cartridge/markup.cpp:351,404,618

firmware_appended: firmware can be appended to end of ROM file.

SGB boot ROM NOT embedded (sgb.boot.rom from system_dir).

CX4 NOT embedded (cx4.data.rom from system_dir).
