I have a couple of newbie questions.. hope you can help.. sorry to be a nuisance.

1. How do you know if you are running PAL or NTSC? I think im NTSC as i found a sticker under my playstation that says NTSC.. and live in Canada?

2. How do you get a gameshark for PSX?

3. What is a TRAINER?

4. I made a backup of a game, now it 'rolls' on the screen could it be a bad burn or does it need patching?

Thanks for everyones time,
