Despite my vast and great efforts, I have been unable to find a comprehensive list of error codes for the PSP, what they mean and how to fix them. Anyone who has them, access to them, or knows where I may find them, please, PM me, or better yet, post them here for all to see! If you don't have a complete be all and end all of lists, thats fine, just post what you have and you get thanks.
PS. Error Codes that I am most interested in are the ones generated while trying to do things with wireless settings. For anyone who needs to know, I run FW 1.5 (and will not upgrade.)
Thanks in advance to those generous enough to help me out with this.
