How to add custom gameboot to ur psp!

What u will need:

Custom Firmware
usb cord


* Remember you have a small chance of bricking ur psp if u do anything dumb *


Get the gameboot u want have it on hand Plug ur psp to ur pc not on the psp home screen press select( i found this method easier to toggle flash 0 instead of having to turn it off and hold R i have firmware 3.71 m33-2 )
Ok when u press select u will enter the m33 vsh menu, where it says usb mobe change it to Flash 0 go to usb mode on ur psp when ur psp menu Come up on ur pc. Go to the vsh folder then go to recsources minimize that go to ur folder were u have the gameboot u want Gamboot.pmf that how ur gameboot file should be named. Now take ur gameboot drag and drop it in ur psp recsource folder it ask u if u wanna replace the original say yes. Exit usb mode if ur psp is still on Flash 0 change it to memory stick. and There u go ur Custom Gameboot is now on ur psp. Hope my little explination helped if it didnt theres always youtube videos .
