yep
You can paly an PC based game that can use a controller.
Using a play and charge kit
Do not directly plug your controller into the computer. You will need an adapter for connection.
any, you just got to download Controller to keys.
You need to rechange your computer and put a plug like a PS and you can play online with conttroller
PS2 do not play PS3 games and if your PS2 controller is being used on a PS3 then you are not using normal PS3 equipment. Sony support and my sources do not have information on using some unknown controller that might be able to work on a PS3 read your manual that came with the controller. Better yet buy the better Dual Shock 3 PS3 controller
Some games, such as Guitar Hero, are played with a guitar controller. It is not a real guitar. There are many computer programs avaible to teach a variety of instruments, although they are not specifically video games.
No.
You can not play Computer games using the PS3. The PS3 is not a computer in the sense that it is not able to and does not contain all the software present and needed to play computer games that can be found in a laptop or PC.
You might need to buy an adapter to make the controller work on your computer.
It might be possible, but you going to need some programs and it might affect you computer speed.
You need a gamecube controller, classic controller, or a N64 controller with an adapter.
