SN Systems were in the business of creating excellent 3rd party development tools and many game development studios relied on them to provide first class tools for console development. The PSP was no different and SN Systems started developing its PSP version of its popular ProDG SDK sometime in 2003 (as far as we know).

SN Systems (Creator of Development Tools)
For more information about SN Systems check out this post.
The SDK contained the SN Systems Compilers (SNC C/C++) which were optimised specifically for the handheld’s cpu architecture, allowing faster assembly code to be generated compared to Sony’s standard SDK.
The SDK contained a few main parts:
The SDK also contained the ProDG Tuner (Tuner-LE) which was used to for game optimization by visualising code and providing information about where the main bottlenecks are 1.
Similar to the ProDG SDKs for other consoles this SDK included the Target Manager which allowed shared usage of multiple PSP development Kits via the internal network.
Proview is an optional part of the SDK tailored to artists, this allows them to test how their assets look and run on the PSP hardware without having to create a new build of the game. This can be run through the previously discussed Target Manager meaning any artist PC could connect to it similar to a shared network printer.
So far we only know of one versions to exist:
No versions of the ProDG SDK for the PSP have currently been leaked to the internet, although a photo of it had been shared to Andrew Borman’s Twitter:

Although the SDK was third party it was extremely popular among PSP development studios and many games used the SDK’s excellent compilers and debug functionality.
As this is a third party optional SDK not all PSP games would have used it as it is not a requirement and some just used the standard official Sony SDK.
However the SDK was still very popular and according to TotalVideoGames.com 20 out of the 24 launch titles for the PSP were created using the ProDG SDK! 2.
Known games include:
If you are interested to find out if a certain game used this SDK then you can run the strings command on the main game executable.
Below is an example of strings that hint at the use of the SN Systems SDK:
