ok fixing consals are extreamly hard.if u move 1 false item its broken forever.so if u have a friend ora family member who is a good person to fix things tell them to look at it.if u don't know any one go to a game stop or head GAMES.they will charge money depending on wat needs to be fixed.(if it is a gameboy,andvanced sp,or a psp or a ds screen problem it might not be fixable).controllers are usaly easy and hard depending on the system and the type of controller.first if it is a wireless controller change the abtetries if it doesn't work it will need repair or just let it sit for a while it might work.if there is a loose wire on any contrller emmidiatly fix it!it will get worse!take scotch or duck tape and rap it around at least 5-10 times.if none of the above are there or working rub ur fingers up the wire.if it loose take it to get fixed.GAMES if they have big scratched u may have to sell it.(i mean have to).if it has a mark on it take it to a game store and get it cleaned!thats all i have to sya thanks for reading!
