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.)

|
|
Holani is a cycle-stepped Atari Lynx emulator written in Rust by LLeny.
|
|
The libretro port (holani-retro) loads lynxboot.img from the system
|
|
directory at retro_load_game time (lib.rs:110-121). Path is built as
|
|
system_directory + "/lynxboot.img", no subdirectory.
|
|
|
|
The core library (holani/src/rom.rs) embeds a free boot ROM from
|
|
https://bjoern.spruck.net/lynx/ as FREE_BOOTROM (512 bytes), used as
|
|
the default when no external ROM is loaded (Rom::default()). The
|
|
libretro wrapper attempts to load the real lynxboot.img, but if the
|
|
file is missing or the system directory is invalid, Lynx::new() already
|
|
has the free boot ROM initialized. No hash validation on the external
|
|
file; Rom::from_slice() only checks length == 512.
|
|
|
|
Unlike Handy and Gearlynx, Holani always boots because the free ROM
|
|
is compiled in. The real BIOS provides more accurate boot behavior
|
|
(encrypted cart loader, original RSA key), while the free ROM
|
|
reimplements the boot sequence without proprietary code.
|
|
|
|
ROM extensions: .lnx, .o
|
|
Core options: none.
