@ -41,7 +41,7 @@ Throughout the project, every function at every stage either **does exactly what
- [sceAvPlayerSetTrickSpeed](../../core/libs/prx/libSceAvPlayer/src/Source.cpp) (libSceAvPlayer) with a negative speed runs the clock backwards but delivers no frames; when a forward speed is set again, playback resumes from the rewound time.
- [sceRudpActivate](../../core/libs/prx/libSceRudp/Export.cpp) (libSceRudp) - there is no reliable-UDP stack on the host to activate, so it returns success without doing anything, as [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/rudp/rudp.cpp) does for its own `sceRudpActivate`. PPSA01325 calls it with no arguments during start-up; what the console activates, and whether it reports an error before `sceRudpInit`, is unverified
- [ulobjmgr](../../core/libs/prx/ulobjmgr/Export.cpp) registers no object: `_sceUlobjmgrRegisterObject` always hands out id 0 and `_sceUlobjmgrUnregisterObject` releases nothing, as shadPS4 does
- [libSceHttp](../../core/libs/prx/libSceHttp/Export.cpp) - no request reaches the network, so `sceHttpSetResponseHeaderMaxSize` has no response header to limit, `sceHttpSetRecvBlockSize` (`(int id, u32 blockSize)` as in [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/network/http.h)) no response body to read in blocks and `sceHttpRedirectCacheFlush` no redirect to forget; `sceHttpsUnloadCert` returns success like `sceHttpsLoadCert`, which keeps no certificate; `sceHttpSetRedirectCallback` and `sceHttpSetCookieRecvCallback` accept callbacks that are never called, `sceHttpsSetSslVersion` has no TLS connection to configure and `sceHttpsGetSslError` reports error 0 with detail 0; `sceHttpSetAuthInfoCallback` accepts a callback that is never called, as no server asks for authentication; `sceHttpsGetCaList` and `sceHttpsFreeCaList` report an empty CA list (`certs` null, `certsNum` 0) and return 0, as no CA store is kept, and a null list returns `ERROR_INVALID_VALUE`. The signatures and the `{ void* certs; int certsNum; }` layout follow [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/network/http.h) (PS4), not confirmed on a PS5 title
- [libSceHttp](../../core/libs/prx/libSceHttp/Export.cpp) - no request reaches the network, so `sceHttpSetResponseHeaderMaxSize` has no response header to limit, `sceHttpSetRecvBlockSize` (`(int id, u32 blockSize)` as in [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/network/http.h)) no response body to read in blocks and `sceHttpRedirectCacheFlush` no redirect to forget; `sceHttpsUnloadCert` returns success like `sceHttpsLoadCert`, which keeps no certificate; `sceHttpSetRedirectCallback` and `sceHttpSetCookieRecvCallback` accept callbacks that are never called, `sceHttpsSetSslVersion` has no TLS connection to configure and `sceHttpsGetSslError` reports error 0 with detail 0; `sceHttpSetAuthInfoCallback` accepts a callback that is never called, as no server asks for authentication; `sceHttpsGetCaList` and `sceHttpsFreeCaList` report an empty CA list (`certs` null, `certsNum` 0) and return 0, as no CA store is kept, and a null list returns `ERROR_INVALID_VALUE`; unlike shadPS4 they do not check that `http_ctx_id` is a live context nor that the library is initialised, and `sceHttpsFreeCaList` also nulls `certs`, which shadPS4 leaves untouched. The signatures and the `{ void* certs; int certsNum; }` layout follow [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/network/http.h) (PS4), not confirmed on a PS5 title
- [sceFontGlyphDefineAttribute](../../core/libs/prx/libSceFont/src/Render.cpp) (libSceFont) checks the glyph and ignores the attribute and its value, whose meaning is unknown. PPSA01325 sets attribute 0x11 to 0 on a glyph from `sceFontGenerateCharGlyph` that it deletes unused, and draws the character with `sceFontRenderCharGlyphImageHorizontal`
- [sceAudioInInit](../../core/libs/prx/libSceAudioIn/Export.cpp) (libSceAudioIn) - returns 0 without library-wide setup, as `sceAudioOutInit` does; each `sceAudioInOpen` opens its own SDL capture device
