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 https://github.com/DNNDHH/PS5-3.20_Libs/tree/b2a77c09cd71c01f34c790cfbe98c751a13262ad

libSceDiscMap technical debt
Silent stubs
- libSceDiscMap implements only the state with no disc bitmap:
sceDiscMapIsRequestOnHDDandioKMruft1ekreturnSCE_DISC_MAP_ERROR_NO_BITMAP_INFO(0x81100004) for every request and write nothing. CUSA02636's bundledlibSceFios2.prximports both; what it does with the error is not known (shadPS4 returns the same, and shadps4-game-compatibility #617 lists CUSA02636 as in-game)
Unknown function info
- sceDiscMapGetPackageSize (libSceDiscMap) - its name and NID are in the PS5 3.20 export inventory; the
(int64_t, int*, int*)prototype follows shadPS4, is not measured on a console, and every call throws - sceDiscMapIsRequestOnHDD, sceDiscMapUnknown_ioKMruft1ek (libSceDiscMap, NIDs
lbQKqsERhtEandioKMruft1ek) -ioKMruft1ekhas no known name. The(path, offset, size, result)and(path, offset, size, flags, out1, out2)signatures follow shadPS4 disc_map.cpp; the widths of theioKMruft1ekoutputs are unknown (shadPS4int*, fpPS4PInt64), so they arevoid*. The error code is the one both return; shadPS4 #2686 reads the console library as checking an initialisation global first in each call and returning it while the global is clear. Not measured on a console
