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

Keyboard input follows libSceMouse: the video out event loop forwards SDL
key and focus events, whose scancodes are USB HID usages, and the library
keeps the pressed keys, modifiers and lock LEDs in a 16-entry history for
sceKeyboardRead and a snapshot for sceKeyboardReadState.
sceKeyboardGetKey2Char translates the 101-key arrangement; the 106-key
one throws and is listed as technical debt.
KeyboardData holds 16 key codes (96 bytes), not 6.
