Syscon G-Sensor
As I mentioned in previous entries, support for an internal HDD+GSensor had been added to the kernel from 2.80. It seems SCE had wanted to keep it a secret since when I had revealed the NID’s referencing these devices, the API had promptly been removed the following firmware. Hence the HDD & GSensor NID’s only exist from 2.80-3.60. When they actually plan on releasing this HDD is anyone’s guess, though I had hoped it would have happened with the release of the PSP-3000. Well, maybe for PSP-4000…

From sceSyscon_driver:

• 0x3357EE5C sceSysconIsFalling
• 0x565EF519 sceSysconGetFallingDetectTime

This literally detects whether or not the PSP is falling down (the G-Sensor has an accelerometer built in) and if it is, shuts down the HDD to protect from damage.

Lightweight Mutex
Lightweight mutexs have recently been added to the kernel (3.80+ firmwares) however the majority of the API was placed in the sceKernelLibrary of usersystemlib.prx instead of sceThreadManager even though sceKernelCreateLwMutex/sceKernelDeleteLwMutex were still in sceThreadManager.

From Kernel_Library:

• 0xBEA46419 sceKernelLockLwMutex
• 0x1FC64E09 sceKernelLockLwMutexCB
• 0xDC692EE3 sceKernelTryLockLwMutex
• 0x15B6446B sceKernelUnlockLwMutex
• 0xC1734599 sceKernelReferLwMutexStatus

From ThreadManForUser:

• 0x4C145944 sceKernelReferLwMutexStatusByID

Low-level Sound Library
From 1.00-2.60 a low-level sound library was available as the scePEQ_Library_driver (peq.prx).

From scePEQ_driver:

• 0xF7EA0632 scePeqInit
• 0x213DE849 scePeqEntry
• 0xED13C3B5 scePeqProc

From 2.70+ this library was replaced with sceSAScore (sc_sascore.prx – SC being the shorthand for the main cpu as opposed to ME the Media Engine cpu).

From sceSasCore_driver:

• 0xB0F9F98F sceSasCoreInit
• 0xE143A1EA sceSasCoreExit

For the usermode library the usual naming convention changed (no wonder there were never any hits for these nids, they used a stupid underscore, and two of them!!)

From sceSasCore:

• 0x019B25EB __sceSasSetADSR
• 0x07F58C24 __sceSasGetAllEnvelopeHeights
• 0x267A6DD2 __sceSasRevParam
• 0x2C8E6AB3 __sceSasGetPauseFlag
• 0x33D4AB37 __sceSasRevType
• 0x42778A9F __sceSasInit
• 0x440CA7D8 __sceSasSetVolume
• 0x50A14DFC __sceSasCoreWithMix
• 0x5F9529F6 __sceSasSetSL
• 0x68A46B95 __sceSasGetEndFlag
• 0x74AE582A __sceSasGetEnvelopeHeight
• 0x76F01ACA __sceSasSetKeyOn
• 0x787D04D5 __sceSasSetPause
• 0×99944089 __sceSasSetVoice
• 0x9EC3676A __sceSasSetADSRmode
• 0xA0CF2FA4 __sceSasSetKeyOff
• 0xA232CBE6 __sceSasSetTrianglarWave
• 0xA3589D81 __sceSasCore
• 0xAD84D37F __sceSasSetPitch
• 0xB7660A23 __sceSasSetNoise
• 0xBD11B7C2 __sceSasGetGrain
• 0xCBCD4F79 __sceSasSetSimpleADSR
• 0xD1E0A01E __sceSasSetGrain
• 0xD5A229C9 __sceSasRevEVOL
• 0xD5EBBBCD __sceSasSetSteepWave
• 0xE175EF66 __sceSasGetOutputmode
• 0xE855BF76 __sceSasSetOutputmode
• 0xF983B186 __sceSasRevVON

Under the same prx another sound lib, the Positional 3D Audio Library, was added in 2.80+.

From sceP3da:

• 0x374500A5 sceP3daBridgeInit
• 0x43F756A2 sceP3daBridgeExit
• 0x013016F3 sceP3daBridgeCore

User Log
Added from 2.80+, can only be used on devkits.

From UtilsForKernel:

• 0x92282A47 sceKernelRegisterUserLogHandler
• 0x87E81561 sceKernelPutUserLog

NP DRM
As people may know SCE added their own official UMD Emulator to load official PSP ISO’s bought from PSN Store (such as “Beats” and many others). The scePspNpDrm_Driver (npdrm.prx) is what protects these legit ISO’s. This prx was added in 3.00 way before the actual UMD Emulator (np9660.prx) was added in 3.50 which was even quite a while before it was actually officially enabled. It was unofficially enabled beforehand under M33 CFWs as the NP9660 No-UMD ISO Loader.

From scePspNpDrm_driver:

• 0x17E3F4BB sceNpDrmVerifyAct
• 0x37B9B10D sceNpDrmVerifyRif
• 0x00AD67F8 sceNpDrmGetFixedKey
• 0x5667B7B9 sceNpDrmGetContentKey
• 0xD36B4E6D sceNpDrmGetModuleKey
• 0x0F9547E6 sceNpDrmGetVersionKey (incorrectly listed as scePspNpDrmInitFromGameIdMs4 on the libdocs)
• 0xA1336091 sceNpDrmSetLicenseeKey
• 0x9B745542 sceNpDrmClearLicenseeKey
• 0x275987D1 sceNpDrmRenameCheck
• 0x08D98894 sceNpDrmEdataSetupKey
• 0x219EF5CC sceNpDrmEdataGetDataSize

VSH System Config
The vshRegSysconf lib was previously under the sceVshCommonUtil_Module upto 1.50. From 2.00 the lib was moved to the the vsh_module.

From vshmain:

• 0x03BB4503 vshRegSysconfGetCharacterSetOem
• 0x67BFD9C0 vshRegSysconfSetCharacterSetOem
• 0x0FE13026 vshRegSysconfGetCharacterSetAnsi
• 0x032D663E vshRegSysconfSetCharacterSetAnsi
• 0xF859FC3C vshRegSysconfGetThemeSystemColor
• 0xEE3D8305 vshRegSysconfSetThemeSystemColor

Note: I have yet to add these new NID’s to the libdoc site. I will do so when I get some spare time.
