buncha questions

[Ruffian]

i cant figure anythign out myself so ill ask every last question i can
i need more help than the kid at school with the helmet and kneepads that falls out of the short bus every morning

1. Can I use NitePR hacks playing with a UMD game?
2. How do you download games? I put it on my computer and it's lost forever
3. How do you put hacks in NitePR? I only have hacks my friend gave me :P
4. Does it mattery if my pandora battery is for or slim? As long as it fits in my PSP, right?

im sure these questions are simple for you, the only hard part is wasting minutes of your life typing the answers
