PS2 Analog Stick Sensitivity

[PS2Quality7]

Is there a way to change the PS2 Dual Shock 2 Controller's Analog Stick Sensitivity?

For some PS2 games, you can walk by moving the left analog stick slightly, and run by holding the left analog stick further?

Is there a program that can change the sensitivity of the left or right analog stick?

Not to my knowledge, no.

Making such a program would be quite complex, similar in many ways to the implementation of IGR (In-Game-Reset) for game loaders such as OPL, in that it requires interacting with a gamepad driver module loaded by the currently running game. It would be easier if Sony had made it so that all games had to load the same drivers from the bios ROM, as there would then only be a single set of functions to intercept and interact with, according to a single standard. But that is not how it works. Instead most games load drivers for gamepad and other devices from the game disc, and the gamepad drivers often vary widely between different games. Some support USB controllers while others don't, some support multi-tap while others don't, and so on.

A utility of the kind you want needs to be able to intercept not just one, but all of these driver types as they are loaded, and then interact with them in some way to rescale their joystick response, which is bad enough with just one standard to contend with, but extremely hard to do with multiple standards...

In short:
While it definitely is possible to do something like this, it is quite hard to do, and I don't think anyone with the ability to do it is sufficiently motivated to take this job on.
