Hello I was hoping someone could help me with modding my psp. I am completely new to this but I really would like to able to play PSX games but still be able to play recent games
My psp's firmware is currently 3.51 and these are my questions:

1)Do I definitely need a pandora's battery to downgrade first?
2)Once it's downgraded how do I install custom firmware?
3)What's the ideal CFW to play PSX games? (but is still able to play recent games that require an update)

If someone could help me out or provide a link answering these questions it would be very much appreciated. Thanks
