PRAGMATA (PPSA02530) imports sceSharePlayProhibitController (NID FzQS6DREDfk), which no library exports on main, so the load fails on the unresolved import. It is one of the "six declared-only imports" of xXPBSXx's branch in #3043 (comment 6107100345): "These only stop the load failure; as described above, the title calls some of them later and needs their real behavior." sharpemu src/SharpEmu.Libs/Share/SharePlayExports.cs:9-31 (a2983692930564815a77f81e74c151268f5b935f, used as a source of facts) takes one value, accepts 0 and 1 and returns 0. Nothing here would read the setting, as no Share Play session or visitor controller exists, so it is not stored. sharpemu rejects other values with its synthetic 0x80020003, not a Share Play code, so they throw, as sceSharePlayInitialize does for its unknown error. Like the other exports of the library it does not check initialization. The NID hashes from the name and is in aerolib. Unverified points are in TechnicalDebt.

### Unknown function info
|
|
|
|
- [sceSharePlayInitialize](../../../core/libs/prx/libSceSharePlay/Export.cpp) (libSceSharePlay) - the library keeps no state, so the heap is not used. A null heap is accepted: PPSA11386 passes a null heap and 0x1800 bytes and stops on any non-zero result. The error for a zero size is unknown, so it throws

### Functional
|
|
|
|
- [sceSharePlayGetCurrentConnectionInfoA](../../../core/libs/prx/libSceSharePlay/Export.cpp) (libSceSharePlay) - reports no Share Play session, as the library keeps none: status 0 (DORMANT), mode 0, empty online IDs, account IDs 0 and both user IDs -1 (`SCE_USER_SERVICE_USER_ID_INVALID`). A null pointer returns `SCE_SHARE_PLAY_ERROR_INVALID_ARGS` (0x810E0001). The 72-byte `SceSharePlayConnectionInfoA` layout and the error code follow [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/main/src/libs/libNet.cpp) and [fpPS4](https://github.com/red-prig/fpPS4/blob/trunk/src/ps4_libsceshareplay.pas), which agree on both; KytyPS5 sets the user IDs to -1 and fpPS4 leaves them 0, and which one the console returns is not verified. KytyPS5 also returns `SCE_SHARE_PLAY_ERROR_NOT_INITIALIZED` before `sceSharePlayInitialize`; this library keeps no initialization state and does not.

- [sceSharePlayProhibitController](../../../core/libs/prx/libSceSharePlay/Export.cpp) (libSceSharePlay) - accepts 0 (allow) and 1 (prohibit) and returns 0, following [sharpemu](https://github.com/sharpemu/sharpemu/blob/a2983692930564815a77f81e74c151268f5b935f/src/SharpEmu.Libs/Share/SharePlayExports.cs#L9-L31). The setting is not stored, as no Share Play session or visitor controller exists and no export reads it back. sharpemu rejects any other value with its synthetic `0x80020003`, not a Share Play code, so other values throw. Like the other exports here it does not require `sceSharePlayInitialize`. The `int` argument type and the console's error for other values are unverified
