Then extract the nokxploit from the Mac Address Changer to your desktop.
Then open up the nokxploit folder on your desktop and there should be a g54macid folder. Then connect your psp and put this folder in your PSP/GAME150.
Then disconnect your psp and go to game/MEMSTICK then g54macid and run it, then hit X and wait for it to dump your mac address. Once it finishes dumping it should boot you out back to your main menu, then you connect your psp agian and it should have a file called macid.bin in the root of your memory stick.
Now make a file folder on your desktop for you and the person your making it for
then drag the macid.bin file into your and the person your making it for's folder.
Then take the one in the person your making it for's folder and right click and click open with then Select Cynus Hex Editor.
Then change your mac address to the persons your making it for then save it.
Then drag that copy to the root of your memory stick then where it asks you to replace click yes.
Now disconnect your psp and go back to g54macid and run it and press L+O then wait for it to finish that then connect your psp again and go into PSP then SAVEDATA then cut and paste the UCUS98645 files into your file folder on your desktop.

Then disconnect your psp and go to PSP/SAVEDATA then cut and paste the UCUS98645 folder onto your desktop.
Then take that file and depending upon what you use zip it up.
