ay! I'm new and need to know sum answer. thanks

1.) What does the patch really do to the game?
2.) When i burn cd games there are some games that the screen are out of place(if i try to swap for ps2). Is it the burning program i use(nero..but it still works. dunno if it works perfectly tho), or is it the type of cdr i use(Memorex)
3.) What is NTSC and PAL?

sorry for so many. thanks
