MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

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.
