|PSP Dev Wiki|
The PSP Developer Wiki is a wiki for developers and those wishing to educate themselves on the inner workings of the PSP. The wiki created in June 2017 encompasses Dark_Alex's PSP Dev Wiki which went defunct in 2008 and combines it with various other PSP developer wikis, blogs by developers, and various other PSP related sites which no longer exist.
Not only does the wiki hold information from when the PSP was the center of attention, but also contains information from the years since that was not documented on a wiki before.
The PSP may not be the most popular device any more, but it has a lot of life in it and still has plenty to give.
