SysMemForKernel library (from 2.50 fw onwards):
- 0x071d9804 sceKernelApiEvaluationInit
- 0x049CC735 sceKernelApiEvaluationReport
- 0×02786087 sceKernelRegisterApiEvaluation
All these functions just return 0 in the retail sysmem.prx which suggests it’s used in devkits only. Sounds like a reporting tool but no idea what kind of data it will log.
UtilsForKernel library:
- 0x136f2419 sceKernelSetPTRIGMask
PTRIG is some sort of switch on a devkit similar to the dipswitches. Do not know what it controls.

The final remaining idstorage nid:
- 0x99ACCB71 sceIdStorageCreateAtomicLeaves
As the name suggests, this function creates multiple leaves as an atomic operation. Because each leaf is only one nand page in size (0×200 Bytes), data requiring more than 0×200 bytes will need more than one leaf. This function allows you to create multiple leaves as a single operation. This saves from having to sceIdStorageCreateLeaf each individual leaf.
A good example of this are the umd keys (0×102-0×106), which hold a single continuous stream of data split over 5 seperate leaves:
C:
-
// leafid is an array of leaf ID’s to be created
-
// numLeaves is the number of leaves to create
-
int sceIdStorageCreateAtomicLeaves(u16 *leafId, int numLeaves);
-
-
u16 umdKey[5] = {0×102, 0×103, 0×104, 0×105, 0×106};
-
-
sceIdStorageCreateAtomicLeaves(umdKey, 5);
That finally completes the idstorage lib !!

Finally got around to updating the libdocs (http://silverspring.lan.st/update.html).
Thanks to Insert_Witty_Name for the full sceNetAdhocTransInt_Library nids, and WosRet for some very nice sysmem/kdebug nids:
- 0x24C32559 sceKernelDipsw (devkit dip switch settings)
- 0x39F49610 sceKernelGetPTRIG (I don’t know what these are, more devkit stuff?)
- 0xCE8D3DB3 sceKernelGetQTGP2
- 0x6D8E0CDF sceKernelGetQTGP3
Some nids from brand new modules like the 1seg TV Tuner and the G729 Audio Compression algorithm used for Skype:
- 0xf8e2cedc sceUsb1SegScanCh
- 0x5f62e0b5 sceUsb1SegChangeCh
- 0xcfcd367c sceG729EncodeInit
- 0x55e14f75 sceG729DecodeInit
And an unusual change from the standard naming conventions:
- 0xfa6de6a6 _sce_pspnet_if_up
- 0xedb11cb4 _sce_pspnet_if_down
- 0x701dddc3 _sce_pspnet_if_attach
- 0xd5a03bc0 _sce_pspnet_if_detach
Also added 3.95 firmware (http://silverspring.lan.st/3.95/index.html), not surprisingly nids were changed again from the 3.90/3.93 firmware, but at least there’s some new modules (like libaac).
I will probably only update firmwares 1.50 & 3.52 (as well when a new firmware comes along) from now. !.50 for obvious reasons since 1.50 homebrew is still strong, and 3.52 since that was the last update before SCE started randomising the nids.
