Lunar - Silver Star Story Complete (Japan) needs the MPEG card and stops Yabause after its logos. Lunar - Silver Star Story (Japan) reaches its title on Beetle Saturn and Yabause with the RetroArch pack's BIOS (records 2026-10-28-6b5b55d3480f, 2026-10-28-9270d1928be7), judged against the reference frames added to the oracle.
fallback_patterns and load_patterns for Beetle PSX and HW, SwanStation, PCSX-ReARMed and Flycast, each read from the core's source at its pin. Beetle maps OpenBIOS when its firmware is missing and loads a file of another sha1 all the same. SwanStation names the image it uses or falls back to, and its OpenBIOS. PCSX-ReARMed loads another region's file before its HLE BIOS.
Puzzle Bobble 2 (Japan) and Bust-A-Move 2 (Europe) on the PlayStation cores, and the three Saturn editions on Beetle Saturn, each frame reviewed on its PNG. Beetle Saturn's BIOS error lines, read from ss.c, are its error patterns.
hle_fallback needs the file to change the run: Beetle PSX hashes every file of its folder, so opened is not used. PCSX-ReARMed hides the BIOS logo by default: its BIOS load line stands for the bios stage. A check runs again only when the oracle entries of its content and core change, and the rules run on every pass from the kept records.
Bust-A-Move 2 (USA) on Beetle PSX, Beetle PSX HW, SwanStation, PCSX-ReARMed and PCSX1, each frame reviewed on its PNG. A boot needs a screen of the game: the BIOS screens alone are not one.
core_probe writes record version 4. Each run is boots, bios_error, crash, hang or unknown, from reference frames, core error patterns and screens, and the process status. A crash or a timeout is a verdict now, rebuilt from the events the worker streamed. --vary accepts @zeros:SIZE and @head:SIZE:PATH, and run takes --repeat.
