Unknown function info

• sceBufferAlloc, sceBufferDup, sceBufferFree, sceBufferRealloc, scePlayReadyApiIsStarted, scePlayReadyApiStart, scePlayReadyApiStop, scePlayReadyBufferFree, scePlayReadyBufferMalloc, scePlayReadyBufferRealloc, scePlayReadyContentGetProperty, scePlayReadyContentSetProperty, scePlayReadyDomainCertEnumFini, scePlayReadyDomainCertEnumInit and scePlayReadyDomainCertEnumNext (libScePlayReady) - names and NIDs are present in the PS5 3.20 export inventory, but no credible prototypes were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified
• scePlayReadyDomainCertFind, scePlayReadyDomainJoinGenerateChallenge, scePlayReadyDomainJoinProcessResponse, scePlayReadyDomainLeaveGenerateChallenge, scePlayReadyDomainLeaveProcessResponse, scePlayReadyEnvelopeClose, scePlayReadyEnvelopeGetSize, scePlayReadyEnvelopeInitializeRead, scePlayReadyEnvelopeOpen, scePlayReadyEnvelopeRead, scePlayReadyEnvelopeSeek, scePlayReadyFinalize, scePlayReadyFreeDecryptContext, scePlayReadyInitialize and scePlayReadyLicenseAcqGenerateAck (libScePlayReady) - names and NIDs are present in the PS5 3.20 export inventory, but no credible prototypes were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified
• scePlayReadyLicenseAcqGenerateChallenge, scePlayReadyLicenseAcqGetAdditionalResponseData, scePlayReadyLicenseAcqProcessAckResponse, scePlayReadyLicenseAcqProcessResponse, scePlayReadyMemAlloc, scePlayReadyMemFree, scePlayReadyMemRealloc, scePlayReadyNewDecryptContext, scePlayReadyReaderBind, scePlayReadyReaderCommit, scePlayReadyReaderDecrypt, scePlayReadyReset and scePlayReadyStoreCleanup (libScePlayReady) - names and NIDs are present in the PS5 3.20 export inventory, but no credible prototypes were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified
• sceBufferInit, scePlayReadyBufferInit, scePlayReadyApiInitializeInitParams, scePlayReadyInitializeInitParams, scePlayReadyApiVersion and scePlayReadyApiVersionString (libScePlayReady) - prototypes and behaviour follow firmware 13.42's libScePlayReady.sprx, read from disassembly and run natively, not measured on a console. The buffer calls clear 0x18 bytes and the init-params calls clear 0x138 bytes and then write 0x50524459 and 1 as the first two 32-bit words; what the fields mean is unknown, so the calls take void*. The version string is one static 32-byte buffer that every call rewrites, as in the firmware, so a string returned earlier changes and concurrent calls race; returning PlayReadyInvalidArgument for unwritable pointers in scePlayReadyApiVersion and scePlayReadyBufferInit is a defensive host-protection fallback and console behaviour is unmeasured
