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:
|
|
altirra_note: >
|
|
The Altirra OS/BASIC replacements are open-source alternatives compiled
|
|
directly into the core binary (roms/ directory in source). They provide
|
|
good compatibility for most software but real ROMs give better accuracy.
|
|
cfg_note: >
|
|
On first boot the core creates .atari800.cfg in the frontend home directory.
|
|
It scans the system directory for ROM files by CRC32 first, then by filename.
|
|
The core option atari800_opt1 controls whether this legacy config is loaded.
|
|
machine_selection: >
|
|
Core option atari800_system selects the emulated machine. Each machine type
|
|
has its own preferred OS ROM auto-select order defined in sysrom.c.
