- [sceAgcBranchPatchSetThenTarget_0300, sceAgcBranchPatchSetElseTarget_0300](../../core/libs/prx/libSceAgc/Unimplemented.cpp) (libSceAgc) - names from their NIDs (`7Wa3aeJgeVU`, `rP5xLdOf26k`), signatures unknown
- [sceAgcUpdateInterpolantMapping_0100](../../core/libs/prx/libSceAgc/Misc/src/ShaderFusion.cpp) (libSceAgc) - name from its NID (`k0E7vkgqAuE`); the `(regs, vs, ps)` arguments are the declared ones, behaviour unknown
- [sceAgcWriteDataPatchSetDst, sceAgcWriteDataPatchSetCachePolicy and their Async forms](../../core/libs/prx/libSceAgc/Patch/src/WaitRegMem.cpp) (libSceAgc) - the signatures `(packet, uint8 value)` are inferred from the other patch functions, as no public declaration was found; the value is taken in the encoding of the `dst` and `cachePolicy` arguments of `sceAgcDcbWriteData` (graphics) and `sceAgcAcbWriteData` (Async, compute), and the patched packet is the one those calls would write. `sceAgcAsyncWriteDataPatchSetAddressOrOffset` is assumed to patch the address like `sceAgcWriteDataPatchSetAddressOrOffset`, as the compute WRITE_DATA packet keeps it in the same dwords
- [dbOlWdppb4o](../../core/libs/prx/libSceAgc/Shader/src/InterpolantMapping.cpp) (libSceAgc) - unknown name; same arguments as `sceAgcCreateInterpolantMapping`; the `SPI_PS_INPUT_CNTL` bits for `is_f16` 2 inputs follow KytyPS5, not confirmed on hardware
- [dbOlWdppb4o](../../core/libs/prx/libSceAgc/Shader/src/InterpolantMapping.cpp) (libSceAgc) - unknown name; same arguments as `sceAgcCreateInterpolantMapping_0100`; the `SPI_PS_INPUT_CNTL` bits for `is_f16` 2 inputs follow KytyPS5, not confirmed on hardware
- [sceAgcGetDataPacketPayloadRange](../../core/libs/prx/libSceAgc/Misc/src/PacketInfo.cpp) (libSceAgc) - signature, the `{base, size in bytes}` output and the type 0 range (header + 1, one dword longer than the type 1 payload) from KytyPS5 only, matching `sceAgcGetDataPacketPayloadAddress_0090`; prosper returns header + 2 for both types from that address function
- [sceAgcAsyncCondExecPatchSetCommandAddress, sceAgcAsyncCondExecPatchSetEnd](../../core/libs/prx/libSceAgc/Patch/src/CondExec.cpp) (libSceAgc) - no reference has a body for them; they are assumed to patch the COND_EXEC packet like `sceAgcCondExecPatchSetCommandAddress` and `sceAgcCondExecPatchSetEnd`, since `sceAgcAcbCondExec` writes the same packet as `sceAgcDcbCondExec`, as `sceAgcAsyncRewindPatchSetRewindState` does for REWIND
- [sceAgcAcbAtomicGds_0900](../../core/libs/prx/libSceAgc/Acb/src/Control.cpp) (libSceAgc) - name from its NID (`gQkqkLttcpw`), signature unknown
