Functional

• sceRandomGetRandomNumber (libSceRandom) - a null buffer returns SCE_RANDOM_ERROR_INVALID (0x817C0016) even when the size is 0; that is an assumption, not measured on hardware. shadPS4 (PS4, src/core/libraries/random/random.cpp, commit 0614ce324be092791b758d79f93d9f1ca5b10a81) does not check the buffer, and KytyPS5 (PS5, src/libs/libNet.cpp, commit 5e837a9beac82c031868eaad9348d6a48245fb99) rejects a null buffer only for a size above 0, so both return success for a null buffer of size 0. fpPS4 (PS4, src/ps4_libscerandom.pas, commit 04cefd43e6fddd1ab033e7980cd356d14c964905) rejects it, with EINVAL (22) where this library returns the SCE code.
