Kinda technical question (Playstation)

[LINK398]

I wasn't sure where to post this but was just curious how long does the average sony made Playstation 1 controller last? I have a red PSone controller that worked fine this week until all of a sudden the "X" button stops working for the most part. (Need to press really hard and multiple presses for it to work) I thought it was possibly the game (The Legend of Dragoon) but I tried using it just on the sony menu and had the same problem. The controller looks like its in great shape and I've had it for a while. Also do all PS1 games played on a PS2 work with PS2 controllers? Because I'm using a PS2 controller because of this problem.

I still have the original PS1 controller that came with my PS1 and it works. I bought it in 99. My PS1 still works too. :D

And as far as I know, all PS1 games work on the PS2 with PS2 controllers.

The controller can last for years, but the contacts inside can wear away with use, so it's possible you've used it to death. A PS2 controller will play any ps1 or ps2 game on a ps2, as will a ps3 controller play any ps1, 2, or 3 game you have on your compatible ps3. Just if certain games don't have support for analog sticks, the analog sticks will have no function.
