Need files for PSP hack... do they exist anymore?

DX finally stopped messing round and I got myself a Pandora battery... however when following Insanecrazy07's tutorial I bumped into one TEENSY problem...I can't find the 150.pbp or 390.pbp files ANYWHERE... I've googled all over the place, closest I found was a 375.pbp file... but the site it was on looked VERY dodgy and had no other pbp files on it that I saw.
The tutorial is about as simple as you can get (props InsaneCrazy :)) so with the 2 pbp files I'd be able to get this done easily.
(quick related note: Is this the right guide to follow if I want to play PS1 games and eventually play PSP games off the memory stick?)Anyway, can I get any help with this? maybe someone has the files im looking for? or came across a site I might have overlooked?

LOL!Look in my sig, the dumping tools one...Get a freash memory cart and go straight to "5.50GEN-D" and then "D-2" and then...you can try for "d-3" and then "D-3 final" later :)
