Take main's restored signatures (the firmware-database sweep of 2026-10-21):
the typed UsbStorageCallback across the register/unregister family, the
UsbStorageDeviceInfo-typed device-info query, IsExist's three-argument bool
form (succeeds and reports non-existence with no device attached), and
RequestMap's six parameters with the trailing reserved pair dropped. The
no-device answers and the argument validation are unchanged; the guest test
passes an APS5_VABI callback and pins the exists out-parameter.
Nine of the twenty-one exports implement the no-device path: the lifecycle
pair accepts every call and keeps no state, the device queries answer the
empty list, the not-exists 0 and the device-not-found error, the map
requests answer device-not-found with their outputs untouched, and the
getdents family answers device-not-found on open and not-supported with
zero bytes on the read of a never-opened descriptor. The argument
validation of the register, unregister, unmap and getdents-close exports
is implemented and answers 0x80f40002; past it they keep their markers,
because no reference establishes their success path. The device-info
record and two prototypes follow SharpProspero, the rest shadPS4, each
pinned in the debt entry.
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
