i dont think it matters what version PSP you have, it just matters what version of NitePR you use. NitePR Rev K has a program called NitePRed.exe included with it. This program can do alot, like change NitePR button assignments, and change your MAC address for game saves. All you do, is get the person who wants CE's MAC address, hook your PSP up to your computer, enter USB mode. First step is going into ms0:/PSP/Savedata and finding the folder entitled UCUS98645 or UCUS-98645. You have to right click on that folder (it is your savegame of FTB2) cut it, and paste it on your desktop. Next go into your SEPLUGINS folder and RIGHT click on your NitePR.prx, go down to CUT. Now go to wherever you have NitePRed.exe on your computer, right click in that folder and PASTE NitePR.prx into there. Now open NitePRed.exe and you will get a Menu. You want option 1 which is SaveGame MAC Changer. Type 1 and press enter. now you will get another menu, select 1 again for Change MAC. Next it will tell you to input the MAC address, so you enter the MAC address (example: 67:AG:45:63:SD:55 with colons and everything) and press ENTER. Now it will take you back to the main menu, you Type 0 for Save. It will exit the NitePRed program. Now right click on NitePR.prx (because now it has your friends MAC address associated with it) and CUT again. Go back into your PSP and go into SEPLUGINS, right click, and PASTE NitePR.prx back into SEPLUGINS. Exit USB Mode, and start up SOCOM. When you get prompted enter a name and everything, and then turn on..
Infinite CE and Superb LI:
;Raise your LI to superb
Turn codes on with note button. Then go to Profile in the game menu, and go down to Save to save the Inf CE and Superb LI. Once you save it, you can exit FTB2.
Next, go back into USB mode. Go into ms0:/PSP/SAVEDATA and right click on the UCUS98645 or UCUS-98645 folder. Go to Send To and then Compressed Zipped File (if you use WinRAR select add to WinRAR archive). It will create a .zip (or .RAR) file in that folder. Click and drag it to your desktop, and then delete the folder UCUS98645 in ms0:/PSP/SAVEDATA (you dont need it anymore) and then click the FOLDER that you pasted with your Save Game of FTB2 on your desktop and drag it back into ms0:/PSP/SAVEDATA (put it back where it was to begin with).
Almost done. Go back into ms0:/SEPLUGINS/ and right click on NitePR.prx and cut it again. Go to where ever you have the NitePRed.exe and paste NitePR.prx back into that folder. Open NitePRed.exe and select 1 for Save Game MAC changer. Next, select 2 for Reset MAC to Factory Condition. It should take you back to the main menu of NitePRed.exe select 0 for save. Then it should exit the .exe and all you have to do is cut NitePR.prx from that folder and paste it into ms0:/SEPLUGINS and you are done. Then Email the .zip or .rar file to your friend that wants the CE, and tell them to replace their save game folder with the one in the .zip file, and they will have infinite CE.
