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

libSceKeyboard technical debt
Functional
- sceKeyboardGetKey2Char (libSceKeyboard) translates the 101-key (US) arrangement and the alphanumeric layer of the 106-key (Japanese) one, which follows the JIS layout of the HID usages: the Yen (0x89) and Ro (0x87) keys return
\(0x5C) unshifted, as JIS X 0201 places the yen sign there; whether the console returns U+00A5 instead is unverified. With the Kana LED (bit 4, the HID position) set the 106-key arrangement throws, as the kana the console returns are unknown. Ctrl and Alt do not change the character.
Unknown function info
- sceDbgKeyboardClose, sceDbgKeyboardGetKey2Char, sceDbgKeyboardInit, sceDbgKeyboardOpen, sceDbgKeyboardRead, sceDbgKeyboardReadState (libSceKeyboard) - names and NIDs are present in the PS5 3.20 export inventory, but no credible prototypes were found. They are declared without parameters solely to resolve known imports; this is not an ABI claim.
- sceKeyboardConnectPort, sceKeyboardDebugGetDeviceId, sceKeyboardDeviceOpen, sceKeyboardDisconnectAll, sceKeyboardDisconnectDevice, sceKeyboardDisconnectPort, sceKeyboardGetConnection, sceKeyboardGetDeviceInfo, sceKeyboardGetHandle, sceKeyboardMbusInit, sceKeyboardPadEmulateClose, sceKeyboardPadEmulateOpen, sceKeyboardSetProcessFocus, sceKeyboardSetProcessPrivilege (libSceKeyboard) - throwing stubs declared without parameters from the firmware export database (aerolib.csv); their guest signatures are unverified on hardware
