EmuHawk finds every firmware by SHA1 against FirmwareDatabase.FirmwareRecords, and its cores are its own builds. The registry and the scraper both listed libretro cores whose systems overlap BizHawk's, so the pack shipped Clock Signal, O2EM, FBNeo, VICE and Citra files into Firmware/ that EmuHawk never reads. Both lists are now empty, as MiSTer's are: the database alone decides.
BizHawk embeds ares as Ares64, its N64 core, whose 64DD IPL its own
FirmwareDatabase declares. Mapped to the whole ares profile, it pulled
thirty systems into the BizHawk pack and made slots accuse
FirmwareDatabase.cs of a wrong MSX.rom it never declared for ares.
Regenerate database.json and update README counts/timestamps; add and normalize numerous BIOS entries and hashes. Key changes: update generated_at timestamp and system count (355→357) in README; add OpenBIOS / HLE fallback and additional aliases to beetle_psx, include beetle_psx core name and profiled_date update; add laseractive to ares systems; adjust atari800 systems and source_ref line numbers; mark dinothawr as a system and expand its note; update gsplus upstream/profile date, add apple-iie system and tweak source_refs; add pcsx2 core to lrps2; refresh mame profiled_date and add multiple systems and BIOS root sets. Miscellaneous script changes and other JSON normalization to reflect newly discovered/merged BIOS files.
