{block bytes, alignment, block count}requirement, a 32-byte shared-resources parameter with the type at 0 and the{address, bytes}block list at 8 and 16, a context parameter with the block list at 8 and 16 and the shared-resources handle at 0x38, and 8-byte handles written through the first argument and passed back by value. The other context parameter fields (a 16-bit size pair at 0x18, two descriptor pointers at 0x20 and 0x28) are not read. The requirement of four 2 MiB blocks, 2 MiB aligned, is what PPSA08330 v06.006 allocates regardless of the returned count; Sony's values are unknown (KytyPS5 derives 52 blocks for type 0; its layout differs from these calls: it writes a 0x30-byte object through the first argument, where PPSA08330 passes one of two adjacent 8-byte handle globals, and reads the shared resources at context parameter offset 8, where both titles pass the block list). Only type 0 is accepted. The error codes for null pointers, short block lists and foreign handles are unknown, so those calls throw - scePsmlMfsr2CreateContext, scePsmlMfsr2CreateSharedResources, scePsmlMfsr2GetContextInitRequirement, scePsmlMfsr2GetDispatchPackets, scePsmlMfsr2GetDispatchPacketsSizeInDwords, scePsmlMfsr2GetSharedResourcesInitRequirement, scePsmlMfsr2Init, scePsmlMfsr2ReleaseContext, scePsmlMfsr2ReleaseSharedResources (libScePsml_mfsr2) - unknown signatures, imported by PPSA23566; declared without parameters

- scePsmlMfsrInit (libScePsml) - succeeds and only sets the initialized state; the shared resources and contexts are bookkeeping objects that use none of the guest blocks. Whether Sony's library fails on hardware without PSSR is unknown. PPSA08330 calls the setup unconditionally and only uses a context when its cached
sceKernelIsTrinityModeresult is set (0x3c643d, 0x567f97; otherwise it stores a -0.25 mip bias itself at 0x567fe2), which AnyPS5 reports as 0, so the dispatch, mip bias and capture calls still throw
