Over at PSPDev they have released a new version of thier fuction checker. Basically, it brute forces your PSP and looks for fuction names. The goal over at PSPDev is to document the PSP API.

This version has a light version of SHA1 and is twice as fast as the previous version. This version has a a limitation that it can not check for fuction names larger than 55 characters (As far as we know there are none that big anyway.)
