Four files, each with a verifiable origin.
logo.tga and logo_red.tga come from the loader's own resources/logo.h:
hook.c's fread maps FILE_LOGO_TGA to logoLL or logoLLRed depending on
which path was opened, one array per file, so the extraction is exact.
Both decode as valid RLE TGA at their declared lengths.
lgp.zip and timetrav.zip carry crc 0 in Hypseus and in Daphne upstream,
so MAME vouches for them instead. lgp maps onto MAME's set by base name,
confirmed by the five members whose bytes already agreed, and the four
that were missing came from the same set. timetrav is MAME's timetrv:
tt061891.bin, 262144 bytes, crc a3d44219.
The four Sega fonts stay open, and the profile now says why: the loader
embeds one 128x256 atlas and one metrics table answering all four paths,
so it substitutes for the originals rather than reproducing either.
Sixty-nine of the seventy-one sets Hypseus Singe loads, assembled from
atoms retrieved from public archives and rebuilt with torrentzip under
the member names its source expects.
Every set is anchored: the profile already carried each member with its
CRC32, read from Hypseus' own source, so a candidate is either an exact
match or discarded. Sixty-seven verified that way. For gpworld and
firefoxa, Hypseus declares crc 0 and gives no anchor, so MAME's recipe
for the same game vouched for the bytes instead: 17/17 and 6/6.
lgp and timetrav stay out. Hypseus declares crc 0 for both, MAME covers
only 5 of lgp's 9 members and has no timetrav at all, so nothing can
vouch for them and half-verified is not verified.
The six Lindbergh font and logo files gain has_builtin: true. hook.c
serves them from resources/logo.h and resources/font.h unless built-ins
are disabled, so they are not a gap the collection can close.
vba_m carried md5 values taken from docs.libretro.com while its entries
declare validation: [size], which is what src/gba/GBA.cpp:3262-3272 and
src/gb/GB.cpp:2172-2192 actually check. Only the source decides a hash,
so they are gone.
The profile becomes an alias of vbam, and the buildbot name vba-m moves
into its cores: list so target filtering still resolves it.
YAML 1.1 reads an unquoted 01 as the integer 1 and 81 as 81, so the
manager set stopped naming the file its driver opens and the API
published "cores": [2048] as a number where consumers match strings.
Ground truth from MAME 0.289 at the revision the profile cites:
src/mame/vtech/crvision.cpp:957 loads "01" and "23".
The root cause was the scraper: _hash_merge wrote these names through an
f-string, so quoting the profiles alone would be undone on the next
refresh. _yaml_scalar now quotes every name, archive and description it
writes.
