AnyPS5 resolves a title's imports by NID, so a title that imports a system
function no library provides fails to load with an unresolved import. The
PS5 3.20 export inventory lists 193 such exports across 37 PS5 system
libraries AnyPS5 implements but does not provide.
Declare them as throwing stubs so those titles load and reach their next
blocker. Each declaration calls NotImplemented_nid_no_patch and returns 0;
none of them implements the function. Declarations with a credible
prototype use it and cite the source with a pinned commit, and the rest
are declared without parameters, which resolves the import without making
an ABI claim. The technical-debt files record the limitation per library.
libSceMbus and libSceSystemService are left out because pull request #7821
declares them. libSceAgc is left out because its exports are versioned, so
the 3.20 NID names a different symbol from the one AnyPS5 ships.
libSceAvPlayer.native is left out because it compiles libSceAvPlayer's
Export.cpp.
Names and NIDs come from the PS5 3.20 export inventory at

Broken Sword - Shadow of the Templars: Reforged (PPSA21480) decodes its
audio itself and uses AJM codec 23 only to resample interleaved s16 PCM
from 44.1 to 48 kHz: every block initializes the instance with
0, 2, 44100, sets the ratio 0.91875 and decodes 235 frames into a
256-frame output. The run threw "AJM: decoding codec 23 is not
implemented".
A codec 23 run now consumes its whole input and emits every output
frame whose position lies inside it, with the Catmull-Rom of the
existing resampler. Cases the title does not show throw, among them a
run after a resampled run without a new initialize.
Broken Sword - Shadow of the Templars: Reforged stops at AJM decoding codec 23, which is not one of the codec ids known in Ajm.cpp (MP3 0, ATRAC9 1, M4AAC 2, Opus 24).

Ghost of Yotei (PPSA26344, v1.008, eboot 0x2e1cfc) creates an M4AAC
instance (codec 2) and calls sceAjmBatchJobControl with flags
0x200000006000 (RESET | INITIALIZE | SIDEBAND_GAPLESS_DECODE), 8 bytes of
gapless decode plus 8 bytes of M4AAC initialize parameters and an 8-byte
result (#884); INITIALIZE for M4AAC threw on main.
- INITIALIZE (control and sceAjmBatchJobInitialize) reads the 8-byte
{config type (1 ADTS, 2 raw), sampling frequency index} block of
shadPS4 ajm_aac.h at 443f0224; an invalid type or a raw index above 11
returns the invalid parameter result. Raw input is configured from the
instance channels (0 is stereo) as in shadPS4 ajm_aac.cpp.
- RUN decodes ADTS frames (length from the header) and raw access units
(the whole input, as fdk-aac's raw transport) with FFmpeg's AAC decoder
into the instance's S16, S32 or float PCM, with the framework's gapless,
resampling, stream, format and multiple-frames sidebands.
- Without ENABLE_NONDELAY_OUTPUT the first two frames after
initialization or reset produce no output, as in shadPS4. A decoder
error returns CODEC_ERROR | FATAL. The codec info is {heaac, reserved};
the format reports the last frame's bitrate with fdk-aac's formula.
- Throws for what the sources do not settle: ADTS resynchronization,
profiles other than AAC LC, several raw data blocks per frame, channel
configurations other than 1, 2 and 6, more channels than the instance,
HE-AAC without ENABLE_SBR_DECODE, raw input with RUN_MULTIPLE_FRAMES or
several access units, a frame longer than the reserved room, and
unknown codec flags.
guest_ajm decodes an embedded 5-frame stereo ADTS fixture (two chirps,
encoded by FFmpeg 6.1.1's aac encoder at 64 kbit/s) frame by frame, in
one multiple-frames run, as float, as raw access units and with gapless
trimming, and checks sample counts, format, codec info, the delay frames,
RESET, partial input, missing room and the correlation of each channel
with its input chirp at the 1024-sample encoder delay; plus the
INITIALIZE validation results and the refusals.

A family 255 instance with more than one channel carries no stream count
or mapping in its initialization words, so its decoder now opens on the
first packet: the multistream packet's self-delimited streams are counted
(RFC 6716 appendix B), each stream's TOC stereo flag marks it as coupled,
and the channels map in order. A packet whose streams do not make the
channel count throws.
Metal Gear Solid 4 Master Collection (PPSA18194) initializes a 4-channel
family 255 decoder for its intro movie.
