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.
The scraper declared every standalone package launched both ways,
reasoning that RetroArch carries every libretro core. package.mk says
otherwise: it adds ARMSX2 as armsx2-sa only (add_emu_core ps2 armsx2
armsx2-sa true), so the libretro build's pcsx2/resources entries
reached ROCKNIX's list as armsx2-sa files the standalone installs
itself. An emulator is now dual-mode only when package.mk also adds it
as a retroarch core: ten of the 63 standalone names.
Batocera, RetroBat, Recalbox and ROCKNIX offer some emulators both as a
libretro core and standalone. Filed as standalone only, the libretro
layout was dropped: libretro Dolphin had no dolphin-emu/Sys/GC files.
Platforms now name dual-mode emulators and each gets both layouts.
ROCKNIX was declared libretro-only although it packages duckstation,
dolphin, ppsspp and 33 other emulators standalone, and its BIOS list
was read on the next branch under the latest release's version. The
scraper now reads the release tag and lists RetroArch plus every
standalone package.
