no it doesn't
Yes
The PS2 controller is better when would you want to play with a controller that was not as good
no
no
yes, the ps1 controllers are dualshock, and the ps2 are dualshock2, so it may not be as good overall as a ps2 controller, but it should work
Any PS2 wireless controller should be able to work on the PS1. A PS3 wireless controller will definitely not work on the PS2 and PS1, because they use Bluetooth as their wireless technology, whereas wireless PS2 controllers use 2.4GHz as wireless technology.
A Playstation controller will never work as good as a PS2 controller and you need to just buy a PS2 used controller for a few bucks
No it will not PS3 uses a Bluetooth controller that was designed for that system
Yes, but not with games that use pressure sensitivity.
PS1 controllers will work on a PS2. However, PS3 controllers will not work with a PS2.
Of course you could, the jack on both Sony PS1 and Sony PS2 are exactly the same, although it lowers the performance than if you were playing with a Sony PS2 controller which means that you can not actually use the controller because who wants a controller that does not work completely. Used PS2 controllers are cheap and there are no good reasons to try and use a PS1 controller on your PS2 because it will not preform like a PS2 controller
not really
