Groepaz from the ps2dev forums has released "yet another psp documentation" which is a very well written document containing a breakdown of every thing from the PSP's software to hardware. The documentation if far from complete but is the first document released that has compiled all our knowlege of the psp into one place. "There is a lot to be done, and there are probably quite some things that arent very accurate." Hopefully with the communities help we can work to complete this great piece of work.
