The libretro core opens its Kickstart candidates by name and checks
nothing more (libretro.cpp:1804-1867), while its ROM table names each
image by CRC32 and size (rommgr.cpp:159-207, 334-359). The ten named
entries now carry the table's values, so they resolve by content:
kick12.rom moves from a 512 KiB file the table does not list to
KS 1.2 rev 33.180 (a6ce1636) in twelve manifests.
ROM_5200_A, ROM_BASIC_A and six more are atari800.cfg keys, not names
atari800 opens: MatchByName knows only atariosa.rom and its kin
(sysrom.c:278-294), and the keys are config_key since 969907e29. The
twelve labels the scan identifies by CRC32 are found_by: content, and a
platform declaration of a file such an entry accepts by hash, in the
folder the core scans, now meets it: RetroDECK's ROM_BASIC_A answers
atari-basic-rev-a.rom without the alias.
atari800 reads each ROM path from its config key (sysrom.c:123-149,
616-623) and identifies a file by the CRC32 of its slot (sysrom.c:89-
108). AmberELEC's atari800.cfg sets ROM_5200_A, ROM_BASIC_A and
ROM_BASIC_B to 5200a.rom, BASIC_Rev_A.rom and BASIC_Rev_B.rom.
RetroBat and Batocera list ps3_ps2_emu_bios.bin, the PS2 BIOS the PS3
carries for ps2_emu. RPCS3 installed the held PS3UPDAT.PUP (4.90,
sha1 093f8698) and decrypted dev_flash/ps2emu/ps2_emu.self, and the
image is the span firmware_bios_claim release 2 cuts, padded to 4 MiB.
Its romdir parses and ROMVER reads 0220JD20121227. Two runs give the
same bytes, sha1 2dc921be.
RetroBat copies bios/scummvm/extra/Roland_SC-88.sf2 to DOSBox Pure and
DOSBox Staging and offers it in the soundfont option
(DosBoxStaging.Generator.cs:246-252, 336-344). No canonical file of
that name exists, and both emulators take any SoundFont
(dosbox_pure_libretro.cpp:1380-1412, fluidsynth.cpp:194-230).
amberelec_launchers reads runemu.py with ast and, at the commit the
scraper pins, the scripts its standalone table runs and the configs
their packages install: RetroArch and retrorun directories, the MAME
-rp path, atari800.cfg, Hatari's default TOS, amiberry's kickstarts
link and defaults, yabasanshiro, PICO-8, piemu, scummvm, freej2me and
easyrpg. 17 records.
The freej2me-lr.jar and pico8_64 notes now name the file in a sentence
about the emulator, as test_launcher_aliases asks once a launcher
records it.
FluidSynth 2.0.6 (EmuELEC fluidsynth-git, PKG_SHA256 matched) loads
any argument whose header is RIFF sfbk and names no SoundFont.
SC-55.sf2 is named only by emuelec-utils:67 and no EmuELEC package
or script installs or fetches it, so the entry is unsourceable: user
supplied, no canonical file.
XM7 plays fddseek.wav, relay_on.wav and relayoff.wav from its data
directory (linux-sdl/sdl/api_snd2.cpp:155-159, 213-267). The three come
from Win32/ of the XM7 V3.4L77SX+z09 final release archive by PI. and
Ryu Takegami, archived on archive.org as xm7tr_3477sxz09.
Amiberry names every Kickstart its ROM table lists by SHA-1, whatever
the file is called (src/rommgr.cpp:144-378), and a model takes the
first ROM id of its list (src/cfgfile.cpp). The profile carried one of
the 58 images. WHDLoad booting links eight of them into its Kickstarts
folder under their kickNNNNN names (amiberry_whdbooter.cpp:368-375),
which the entries now answer to.
Each blob is TWLCFG 0x88-0x1AF, HWINFO_N 0x88-0x9B and HWINFO_S 0x88-0x9F, read from a retail NAND dump by DSperate's own nand_boot_blobs at ddf2910e. The primary comes from dsi_nand.bin, the seven others from the regional dumps and the dsi_nand.bin variant.
The note named freej2me-lr.jar only in its ROCKNIX sentence, so a
launcher record naming the jar read as a platform choice.
freej2me_libretro.c:488 joins it to the system directory.
sdltrs reads its three ROM slots from the romfile1, romfile3 and
romfile4p options (src/trs_options.c:323-325). RetroPie passes
-romfile4p $biosdir/level4p.rom under the emulator id sdltrs-model4p,
so the pack ships the 4 KB Model 4P boot ROM under that name.
ares binds each firmware path to <system>/Firmware/<type>.<region>
(desktop-ui/settings/settings.cpp:263-264, 280-283). EmuDeck writes a
No-Intro name into NeoGeoPocket and NeoGeoPocketColor BIOS.World, so
the pack now ships the held BIOS under that name.
dsperate-headless reads a 0x154-byte console data blob through --dsi-boot and stops on any other size. The flag has no default, so the name is a label. Without it the bytes come from the NAND's TWLCFG and HWINFO files, are generated for DSiWare run without a NAND, or stay zero in card mode.
openMSX reads the SVI-738 and SVI-738 SE machines' ROMs by the
SHA-1s their machine XMLs list. The disk and BASIC ROMs come from
the MAME svi738 set and match the XML, TOSEC and MAME hashes. The
SE BASIC and RS-232 ROMs were already held under other names.
LoadFileToIPL reads a standalone font with no size check, keeping what fits in the IPL image. The sizes stay as the IPL dump fonts' lengths and the notes say so. No HLE stands in for a missing font: the IPL read raises an alert and the game runs on, so hle_fallback goes.
The standalone runs without the MCPX ROM and the disk image, queuing an error, and stops only without a flash ROM: vl.c clears autostart. bootrom_path, flashrom_path and hdd_path have no default, so their names are labels and the standalone entries lose path. The core still refuses to load without the MCPX ROM or the flash.
The engine checks no hash: only the Windows installer compares the packages.nsh MD5s, so validation and verification go. The content pack stays required from LoadKernel, which exits without a .rmp index at the content root and names the pack.
prepare_dsi_hle refuses a TWLFontTable.dat under 256 bytes and reads its layout from bytes 0x84 and 0x86, warning on a mismatch. No hash is checked, so the three retail NAND sha1s go, and one entry states the size floor and the three layouts.
Batocera's lexaloffleGenerator runs bios/pico-8/pico8 and
bios/voxatron/vox, raises when the binary is missing or not
executable, and puts each folder on LD_LIBRARY_PATH. The new
extractor records both per system from the AST, with the lines
of batocera-43.1 that say it.
