The 43 tos.img aliases in hatari.yml and 10 in hatarib.yml were names Batocera, Recalbox and RetroBat launchers pass to Hatari (hatariGenerator.py, Hatari.Generator.cs, libretroCores.py), now recorded in each platform's launchers: records. With standalone Hatari profiled, those records attach. Measured on Batocera, RetroBat, Recalbox, ROCKNIX and RetroPie: verify statuses, manifest files, omissions and Hatari entries are identical before and after.
Batocera (v2.6.1, hatari.mk), RetroBat (v2.4.1 release), Recalbox and ROCKNIX run standalone Hatari, which the profile did not describe, so their launcher records had no build to attach to. Standalone Hatari reads tos.img from its data directory by default (src/configuration.c:810-812, src/paths.c:316-330), retries a missing name with .img, .rom and .tos (src/file.c:275-308, 481-520), and exits when no TOS loads (src/main.c:191-201). The profile is now standalone + libretro, with the keymap file and the window icon as standalone entries and BOOT.ST scoped to libretro.
apple2gs1.rom and apple2gs3.rom come only from Recalbox's gsplusGenerator.py:107-110, 140, a platform launcher now recorded in platforms/recalbox.yml. No platform resolves gsplus.yml (Recalbox, Batocera and RetroBat run gsplus-legacy), and verify and the manifests of Recalbox, RetroDECK, ROCKNIX and EmuDeck are identical before and after.
RetroPie builds minivmac/minivmac, winterheart/quasi88 and TurtleBazooka/px68k under the package names minivmac, quasi88 and px68k (scriptmodules/emulators/minivmac.sh:12, quasi88.sh:12, px68k.sh:12). With built_by retropie and those names in cores, RetroPie resolves them to minivmac37, quasi88kai and px68k-sdl, while its libretro builds stay reached through retroarch. Measured: RetroPie keeps 532 of 532 platform files OK and gains the 14 files the standalone builds read; no other platform's resolution changes.
RetroBat's ares launcher tries v1.05, v1.02 then v1.01 (Ares.Generator.cs:371-437), now recorded under launchers: in platforms/retrobat.yml. ares itself identifies the image by sha256. No file carries the name, so the database is unchanged.
The profile was pinned at 427556b5 (2.11) while the platform transcribes 2.11.1. In 2.11.1 FirmwareDatabase.cs rates one option per slot Ideal (MCD_eu_100, MCD_jp_100p, SCD_m1_us_110, SMS v1.3, gbaNormal and others), adds TI83_110.rom and a doom2.wad slot (DSDA.cs:85-99), and resizes the TI-83 Plus ROMs. The Ideal option of each slot is the required one, refs into the 12 changed files are remapped, and the 40 firmware files 2.11.1 names that the collection lacked are collected, each sha1-verified (LA_us_102.bin matches No-Intro [BIOS] LaserActive (USA) (v1.02)).
Recalbox builds digarok/gsplus-legacy-archive (gsplus.mk:8-9), Batocera a fork of it whose loading code matches, and RetroBat runs its gsplus-win-sdl release (GsPlus.Generator.cs:26-30). digarok/gsplus, which gsplus.yml documents, is a later KEGS 1.38 import sharing no history with it. The legacy build reads ROM, ROM1, ROM3, ROM01, ROM03, ROM.01, ROM.03 at 128 or 256 KB (src/config.c:863-908), refuses to start without one, and reads c600.rom, parallel.rom and printer fonts as optional.
DuckStation (bios.cpp:208, 397-427), SwanStation (host_interface.cpp:
136-194), rustation (lib.rs:107-160), FS-UAE (rommgr.cpp:92-151),
ares (firmware.cpp:116-136) and Altirra (uifirmwarescan.cpp:29-113)
scan a folder and identify firmware by hash; Ymir does in its
standalone build only. FS-UAE still opens rom.key by name
(rommgr.cpp:1397-1498). The export then stops writing their labels
into platform lists: Batocera's psx block goes from 106 entries to 10,
and System.dat's scph5000.bin keeps its own hashes.
Entries without a system in multi-system profiles were left unattributed by the truth model, and four System.dat additions left the export. Each system is read from the core's code at its pin. hiscore.dat, cheats and history serve every running machine (mame2000 cpuintrf.c:664-666, mame2003 cpuexec.c:280-282, mame2003_plus cpuexec.c:296-298, fbneo hiscore.cpp:154-161 gated on BDF_HISCORE_SUPPORTED), all arcade in those builds, so arcade. BIOS sets take the id their driver gives in the other MAME profiles, and bctvidbs is barcrest-mpu4 everywhere. Files serving several systems of one build (groovymame data files, raine) keep no system. Core resolution is unchanged on every platform.
Generated by mame_hash_scraper --devices from mame0289lx.zip, the release asset whose sha256 matches GitHub's digest. Each set is optional: the core runs without it, and only a machine using the device needs it. 1,252 cite their ROM block, two are written without a ref because two blocks hold the same ROMs. Two note citations now carry their full upstream path.
IPL search order iplrom, iplromxv, iplromco, iplrom30 and font cgrom30, cgrom30.tmp, cgrom, cgrom.tmp (SDL/SDL2/winx68k.cpp:277-331), SCSI ROMs (:140-271), all from $HOME/.keropi (SDL/prop.c:172-194). One IPL and one font are required: without them the CPU loop never starts.
The ROM list is src/memory.cpp:87-100. A missing ROM is filled with 0xFF and the emulator starts, so only N88.ROM, N88SUB.ROM and N88EXT0.ROM, without which nothing boots, are required. The directory is QUASI88_ROM_DIR, else <home>/rom (src/file-op.cpp:444-521). The CMake ROMDIR setting only appears in the help text.
The SDL build reads vMac.ROM, fixed at build time to the Mac Plus ROM name and 128 KB (setup/SPCNFGAP.i:60-63), and checks it against three Mac Plus checksums (src/CONTROLM.h:1344-1388). Search order: --rom, the executable's directory, mnvm_rom/ under the SDL pref path, the working directory (src/OSGLUSDL.c:546-620).
load_pac_bios runs only for .mmi content (platforms/libretro/libretro.cpp:507, 521-522), so pac-n1, pce-lp1 and pac-n10 carry system laseractive, and the system cards nec-pc-engine-cd.
o2em_bios defaults to o2rom.bin and only the chosen file is opened (libretro_core_options.h:52-64, libretro.c:989). Loading fails when it is missing or under 1024 bytes (libretro.c:160-189, 1043-1044). The four files share a variant group, o2rom.bin stays required, the others are optional. Only the first 1024 bytes are read and an unknown CRC still loads, so size becomes min_size and crc32 leaves validation.
hiscore.dat and cheat.zip serve every machine (machine.c:361-363), so arcade. The other twenty BIOS sets take the system ids the other MAME profiles give the same sets, from their drivers (naomi.c:4654-4661 for hod2bios, f355bios, airlbios). mac2bios is declared in macs.c:514, 740, not suprnova.c.
The profile set no system on its entries, so the truth model filed every one under the only profile system a platform has (nec-pc-98 on Batocera, truth.py:487-499). system.rom boots only on PCjr (dos_programs.cpp:2995-2996), MIDI ROMs and SoundFonts serve every machine (mpu401.cpp:678-793), FONT.ROM and the PC-98 bitmaps serve PC-98, the VGA and ROM BASIC images serve the IBM PC. The system BIOS image boots either kind and keeps no system.
A Pentagon, Pentagon 512/1024 or Scorpion reset returns an error when a ROM is missing (fuse/machines/pentagon.c:131-139, pentagon512.c:76-91, pentagon1024.c:72-87, scorpion.c:76-78), machine_select_machine fails (fuse/machine.c:237) and machine_select falls back to the built-in 48K machine (fuse/machine.c:150-162). The core keeps running, so the eight model ROMs are optional.
Every other openMSX entry documents the default file pool folder, share/systemroms. Batocera adds bios/openmsx to the pool and its pack keeps the destination it declares.
Sets the platforms' MAME launches load: CoCo, SCV, BBC, Electron, Mac, Dragon 64, Archimedes and others, each with its members' crc32 from libretro/mame at the pin. The note now states the version the commits pin (0.289) instead of a hand-kept count.
amiga-os-310.rom and Recalbox's kick02019.AROS pair are opened by amiberry's ROM scan (amiberry_gui.cpp, rommgr.cpp at the pin). MinivMacBootv2.dsk is opened by minivmac.
SwanStation hashes the first 512 KB of the 4 MB PS3 ps1_rom.bin, which is its table entry c02a6fbb (bios.cpp:70). Two refs pointed one line off: the hashes are on lines 66 and 71 at the pin.
ps2-0250j-20100415.bin passes the folder scan of pcsx2, armsx2 and yaps2. EmuDeck's SCPH-70004 .BIN, .ROM1 and .ROM2 are aliases in pcsx2, and the .rom1 note now says the stat is case-sensitive.
RetroBat's ares launcher writes the LaserActive BIOS paths into ares's settings, and ares loads them with no hash check. Three EmuDeck Mega CD md5s are images ares's sha256 table names, so their md5 sits beside the sha256.
RetroDECK, ROCKNIX and EmuDeck write Complex.bin or Complex_4627v1.03.bin into xemu's flash ROM path, and Batocera points chihiro at cerbios.bin. They are aliases of Complex_4627.bin.
Ymir standalone identifies an IPL by its XXH128 with seed kIPLHashSeed (memory_defs.hpp:10) against ipl_db.cpp:9-17. Each image's digest was recomputed with that seed and falls on the cited row.
blueMSX names Msx2pe, Msx2pexte, pesadelo and svi328a in its machine configs. openMSX declares the sha1 of nine RetroBat system ROMs in its machine XMLs, and unpacks IDE250.DAT from ide250.zip.
atari800 scans the system folder and recognises each OS and BASIC ROM by CRC32 (sysrom.c:104, 317-420), whatever its name. RetroDECK's ROM_* names are those config keys. Eleven entries carry md5, crc32 and size, under the label altirra already uses for the same dump where one exists.
Batocera, Recalbox and RetroBat choose the TOS file and pass its name to standalone Hatari (--tos, szTosImageFileName) or to hatariB (hatarib_tos): hatariGenerator.py:74-75, 158-193 (Batocera), Hatari.Generator.cs:144-154 (RetroBat). The libretro build still opens tos.img only. The names are aliases of tos.img.
Profile notes and wiki pages called .info entries phantom or incorrect, and labelled an upstream list a known defect. They now state what each file declares and what the code reads. The wiki claimed Batocera prefix-matches truncated md5s; its script compares the full string (batocera-systems:1088), which the page now says. The gaps column reads "Not read by profiles" and notes that a profile may be incomplete.
Recalbox compiles uae4all from Chips-fr/uae4all-rpi (libretro-uae4all.mk:8-9), a libretro core that reads kick34005.A500 from the system directory and nothing else. built_by makes the name resolve to it on Recalbox only.
The libretro core passes system/mame/{hash,plugins,samples} (retro_init.cpp:111-155). Software lists are required in mamemess, where softlists are on by default. The trees and the 19 floppy samples are collected from libretro/mame at the pin.
Seven artwork zips from the core's metadata/artwork are read from mame2003-plus/artwork/ when Display Artwork is on, the default (artwork.c:2242-2258).
The libretro core copies whdboot from the system directory and uses a candidate only when WHDLoad, JST, AmiQuit, boot-data, the game database and the five RTB files are all there (amiberry.cpp:11510-11584). The core zip has none of them, so they are collected.
The standalone build loads it from the working directory then the profile root (app.cpp:5084-5119). The release packages ship it, the libretro tree never reads it.
tilemap.bin and tilepatch.bin are compiled into the core and settings come from core options, so no res/ file or config.xml is opened (omusic.c:50-67, config.c:86-87).
The A500 and LOUD floppy sound sets are read from uae_data/ (driveclick.c:77-104) when the option picks them, and capsimg is loaded from the system folder for IPF images (caps.c:37-96). The ten samples are collected from the core repository.
Since 3fffeb1 prboom.wad is compiled into the core (d_main.c:1449-1465). The IWADs it searches beside the content, in system/prboom/ and in system/ are now listed, with the ZDoom pk3 loaded before a pk3 mod.
The profile listed none. id1/pak0.pak is required (host.c:711-760), the retail and mission pack paks are read in order until one is missing, and Quoth 2.2 is mounted when the content path names it (common.c:1017-1020, 1724-1725). The three Quoth paks are collected, pak1.pak as a release asset.
With colorization set to custom, a DMG game reads palettes/<rom>.pal, then <header title>.pal, then default.pal under the system directory (libretro.cpp:2012-2091). A user-made file, so the entry is unsourceable.
realrtcwdefault.cfg is required (files.c:4364-4368), autoexec.cfg runs unless in safe mode, and eleven pk3 archives are loaded by the scan of main/. All of them ship in the RealRTCW 5.2 package, so they are bundled and stay out of the packs.
legacy_<version>.pk3 is the engine's own build output, named from git describe and different for each release and architecture (ETLBuildMod.cmake:301-316, ETLVersion.cmake:120-131). It is installed with the engine, not downloaded on first run as the note said.
The pin was an unreleased tree past r49 labelled r50, while the rom.bin hashes were r49's. No r50 emulator release exists, so the profile now pins the r49 tag those hashes describe, and names its source repository so the pin is read.
LoadShadersFromDisk opens five shaders and two includes from the hlsl folder beside cxbx.exe and aborts when one is missing (Shader.cpp:812-825, 846-929). They ship in the release zip, so they are bundled.
The pin (1e0de94d) already loads Sega CD, 32X, ColecoVision and LaserActive firmware from the system directory, and the profile still described the earlier core with no BIOS at all. Each file now carries its code reference, required flag and build. The LaserActive player firmware (uPD78237, 64 KiB) is collected from the dump its author published.
