The tools page lists the load and fallback lines each core's BIOS is read from, and core_probe rejudge. The method page says a game can work on the emulator's own BIOS.
region_check and the site name a boot on the core's built-in BIOS as such: the other regions' files were refused. A boot is called another region's BIOS only when the core's log names that file, and a boot whose log names no BIOS says so.
core_probe rejudge appends, for each live record the oracle now judges otherwise, a record with the same runs judged again: verdicts, bios_used and inputs.oracle recomputed, supersedes the earlier one, judged_at and judged_by beside recorded_at. Records of another probe are left to it. The campaign reads a superseded record as its successor, and a file the log shows refused or loaded settles validation with no BIOS screen.
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.
Record version 5: every repetition and variant carries bios_used, staged:<dest> when a load line of the core names the file, builtin when a fallback line says it ran its own BIOS, unknown otherwise. An opened file is no proof. The oracle gains fallback_patterns and load_patterns per core, and a record judged again carries judged_at and judged_by.
code_audit_19 and tui_audit_12. A tap ticks a box and opens a choice on a
second tap of the row the screen saw tapped. One list drives the plan's game
data row, save line and data files. The version note, --offline in shown
commands, exit 2 for a chosen quit, legacy mouse reports read from bytes,
colour roles that read their words, the setup list's device column, the
copy browser, a drive two systems fit, WSL's Windows folder, and line mode
wording.
run_cli entry point, --platform through platform_arg with -p and the registry's suggestion, help on every option, typed probe_lock, options documented, the module in the testing guide. The platform Tested rows fold under one line, run output joined without semicolons, and the measurements page section fits its start-level budget.
Four cores and three games put 430 words on the PlayStation page, past its word ceiling. A system page now shows one line per core, and each game's outcome with its four records waits in a closed fold.
On a console's own page the region block came after the title with no section above it, h1 then h3, and validate_site refused the PlayStation and Saturn pages. It is a section there and stays under the console heading on a maker's page.
Beetle Saturn rerun with its reference frames and error patterns, SwanStation and PCSX-ReARMed run for the first time: each region's game with every regional BIOS, its own only, the others only and the region pack.
PCSX-ReARMed opens the three regional BIOS files whatever the disc, and the rule called that a confirmation because one of them held the region. A run that opened its own region's file and the others too now settles nothing.
The details box takes a plain border instead of a side stripe, dots are rounded squares instead of pills, the strip's label joins variants with full stops, and one file tried reads as 1 file.
Twelve region records made the Beetle Saturn Tested block 266 words where the page allows 120. A region run reads as one outcome per game on the system page, so the emulator page now names them in one line.
DuckStation on Bust-A-Move 2 (USA): boots with scph5501.bin, draws nothing for 90 seconds without it (hang). PCSX2 on Rez (USA): boots with ps2-0230a-20080220.bin, bios_error without it.
When the region's file is absent, libretro.c (7fea57a5) finds no name and no matching sha1, then maps its built-in OpenBIOS (libretro.c:3425-3511). The region runs show it: each region's disc reaches its game with only the other regions' BIOS staged, under the oracle's reference frames (records 2026-10-27-55dd1e4943c4, 13be0e68b799, 33780d47efdf). scph5500.bin, scph5501.bin and scph5502.bin are required: false, hle_fallback stays true. Written through campaign_profiles.
Beetle PSX, Beetle PSX HW and SwanStation rerun under the oracle with the Japanese BIOS menu as an error screen: a Japanese BIOS under a US disc is now a BIOS error.
Without a BIOS, PCSX2 logs and shows 'PCSX2 requires a PlayStation 2 BIOS in order to run'. That line is now one of PCSX2's error patterns, for the next run's verdict: this record was judged without it.
Twelve runs on each of beetle_psx and beetle_saturn: each region's game with every regional BIOS, its own only, the others only and the region pack. One DuckStation check on the US disc with and without scph5501.bin.
Every reference block's run, judged again with the oracle as committed, boots in each repetition. Beetle Saturn's three BIOS lines are BIOS errors, the Japanese menu screens are error screens, and the PlayStation cores carry no error pattern.
