As you can see the naming is very cryptic, but the names do make a little bit of sense (more than some other crypto functions & libs). Each of these functions decrypts a particular ~PSP encrypted executable. The executable type is at offset 0×7C of a ~PSP file, and the executable type number corresponds to the letter listed in the above functions. For example, Type3 exe’s (vshmain modules) use the ‘C’ function to decrypt, Type4 exe’s (user modules) use the ‘D’ function, etc. There are no types 5,6,7,8 exe’s so those letters are missing. Other exe types that use the above functions include:

• Type09 UMD games (use ‘I’ to decrypt)
• Type10 Gamesharing games (use ‘J’ to decrypt)
• Type11 Debug Gamesharing games (use ‘K’ to decrypt)
• Type12 MS Updater (use ‘L’ to decrypt)
• Type13 MS Demo games (use ‘M’ to decrypt)
• Type14 Flash application eboots (use ‘N’ to decrypt)

Later fw added extra exe types also (such as POPS executables – Type20). So as you can see the numbering of the executable type corresponds to the letter of the alphabet used in the decryption functions naming.

Type1 exe’s are internal debug modules while Type2 exe’s are kernel modules, they are both decrypted the same way hence the ‘A’ and ‘B’ in the function sceUtilsGetLoadModuleABLength of memlmd.prx.

Here are also 2 more NID’s from memlmd (these ONLY exist in 2.00 which was when these functions were added into the fw, they were later ‘randomised’ the following update in 2.50):

• 0xc3a6f784 sceUtilsPrepareGetLoadModuleABLength
• 0xdf76975e sceUtilsPrepareGetLoadModuleABLengthByPolling

This function is similar to the ’sigcheck’ functions in that they take an encrypted ~PSP file and ’scrambles’ the ’sig’ area (0xD0 Bytes from offset 0×80-0×150 of ~PSP binaries). The only difference is that this scrambling is not unique per PSP, whereas the normal sigchecking IS unique per PSP (using each PSP’s FuseID to flash the unique prxs, which is why files from different PSP’s are not compatible and therefore cannot be shared).

A few previous Utilities had been added to the PSPSDK most notably the Message Dialogs as well as the Web Browser. Some of these newly discovered Utilities may be also worthwhile to add to PSPSDK especially the Screenshot one. While there are already unofficially screenshot libs, it would be more convenient as well as less memory consuming to use an official lib (for example using the official libmp3 to play mp3 files).

Naturally the PSP would be a suitable target. The library sceMlnBridge (mlnbridge.prx) has existed since 2.50 but only in the last few firmwares has the API really expanded:

From sceMlnBridge (this is not the full list of nids there are still more unknown):

• 0×13e68009 sceMlnBridgeAesEcbEncrypt
• 0×8d7e61dd sceMlnBridgeAesEcbDecrypt
• 0xde730a46 sceMlnBridgeAesCbcEncrypt

• 0xb7e04efa sceMlnBridgeRsaFin
• 0×10c4fec6 sceMlnBridgeSha1MakeDigest
• 0xd455dd97 sceMlnBridgeSha256MakeDigest

Its features include a Public Key Encryption Algorithm, a Public Key Signature Algorithm, a Secret Key Encryption Algorithm, a Secret Key Signature Algorithm, a Digest Algorithm, and more. So here you have access to AES, RSA, SHA1, SHA256, & MT19937 algorithms all in a single usermode lib (though the api was stripped down again from 4.xx for some reason).

All the algorithms are done in software with the exception of AES, which it relies on MagicGate hardware to perform.

From sceMgr_driver:

• 0xA45A63B6 sceMgrAesEcbEncrypt
• 0×19B8F2D0 sceMgrAesEcbDecrypt
• 0xA44A5538 sceMgrAesCbcEncrypt
• 0xA1F6D85A sceMgrAesCbcDecrypt

These are just convenient wrappers over the sceMgrAESEncrypt/sceMgrAESDecrypt functions that were discovered earlier here.

Also, an interface through a USB driver (usbstormgr.prx).

From sceUsbstormln:

• 0×1f4ac19c sceUsbstormlnGetCommand
• 0×5821060d sceUsbstormlnNotifyResponse
• 0×382898de sceUsbstormlnRegisterBuffer
• 0×25b6f372 sceUsbstormlnUnregisterBuffer

• 0×4D2FFC60 sceSysregUsbhostBusClockDisable
• 0xFFEB6E00 sceSysregUsbhostQueryIntr
• 0×87C2BA20 sceSysregUsbhostAcquireIntr

However, these nids were only added in 2.70. At the same time, sceSysregAtahdd___ nids were also added so it could be that this was for the unreleased HDD model PSP and not actually for any current model. Usb Host may have been destined for this new PSP which, along with the internal HDD+GSensor and Bluetooth, defintely would have been a dream handheld.

At one point it seemed that the new PSP-3000 would be the model to integrate these great features however that does not seem to be the case anymore. With the disappointing new features of the PSP-3000 let’s hope a PSP-4000 will finally be the time Sony releases this new model.

Another interesting fact that may mean something or may mean absolutely nothing at all:

0xBC1000B0 is the Usbhost Interrupt Status register. On normal boot this register is set to 1 however on service mode & test mode boot (ie. for battery serial 0xFFFFFFFF & 0×00000000 respectively) this register is set to 0. Whether this actually means something of significance is unknown however it is rumoured that during service mode the USB is actually plugged in (perhaps connected to a testing PC ?).

From sceSyscon_driver:

• 0×3357EE5C sceSysconIsFalling
• 0×565EF519 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.

Low-level Sound Library

• 0xF7EA0632 scePeqInit

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.
