NpTrophy reads the trophy count and icons from the title's trophy
package (names are encrypted and stay not implemented), PS4 v1 save data
calls wrap the native v2/v3 ones, and NpWebApi library contexts, handles
and push event filters work offline (service filters fail without a
signed-in user). libSceAjm is built from the libSceAjm.native sources
for PS4 titles. Limbo's (CUSA01664) remaining PS4 imports, including the
synchronous PS4 TUS calls and the Facebook dialog calls next to the
existing libraries, are exported as not implemented.
Each asynchronous call must start with valid arguments and finish signed out, refuse an unknown request and a non-null option; each synchronous call must return SCE_NP_ERROR_SIGNED_OUT. Targeted cases cover empty virtual users, the operation and sort types and the slot, user, friend and TSS size limits.
The add-and-get, try-and-set, multi-user and friends variable calls (NpId, account, virtual user and cross-save forms) run shadPS4's argument checks and then finish with SCE_NP_ERROR_SIGNED_OUT like the multi-slot variable calls; the synchronous forms wait for their asynchronous ones.
Titles that import libSceNpTus failed to load because the library did
not exist. Title contexts and requests are tracked, arguments are
validated, and every storage operation completes as signed out, matching
how libSceNpManager reports PSN.
