standalone_path is relative to the directories a standalone build
resolves it against, now declared per profile (standalone_directories).
A launcher record that links or passes a whole folder of the BIOS tree
under one of them gives that folder, and platform_layouts rebases the
standalone view once for the builder, the manifest, verify and slots
(launchers.standalone_root, common.standalone_destination).
Flycast on RetroPie and ROCKNIX reads bios/dc, on EmuDeck
bios/flycast/bios, on Batocera (FLYCAST_BIOS_PATH) and RetroBat
(Dreamcast.BiosPath) bios/dc. The ROCKNIX, Batocera and RetroBat
scrapers now record the patched data directory, the environment
variable and the setting that say so.
emulatorLauncher writes a BIOS path into an emulator's configuration
only when the file exists: string x = Path.Combine(bios, "name");
if (File.Exists(x)) ini.WriteValue(section, key, x). The extractor now
records each such write as a fixed_name launcher record, with the
enclosing if and early-return conditions, and a key that receives the
bios folder itself as passes_path. A path reassigned before the check,
or a write under a loop or an else, is not read.
Generators read at 48cdc616: KegaFusion (SCD and 32X keys, GenesisBIOS
given the folder), Jgenesis, MelonDS (DS), Mupen64, Project64, mGBA.
The RetroBat paragraph of the Kega Fusion profile now lives in the
launcher layer.
The scraper reads emulatorLauncher's generators and es_features.cfg at the commit the BIOS list is pinned to: Ares, Hatari, Mesen, Amiberry, WinUAE, PCSX2, the PSX BIOS cascades, Xemu, openMSX and DuckStation. Each extractor raises when its construct is gone.
