Why, yes I can.
The PlayStation Store also has a download of the game for other systems
No you do not need to pay for Playstation Home.
You can't delete playstation network from a psp.
The PlayStation network does not have a charge, but internet service does
Nope its absoloutely free but you have to have wi-fi.
When you select buy game you can pay with funds that are in your Playstation wallet after you confirm your purchase. You add funds to your wallet with a credit card or a Playstation Network card
You pay with your Playstation Wallet Money after you have logged into your account and before you can download the game
Not on the PlayStation Network
No only the Playstation Network is free you mist pay for the internet
Almost as much as if you did not trade in a PS2
you pay money to get a dragon amulet
I'm assuming you mean 'playstation'...
you pay for it with dragon coins.
