Pad plugin with turbo button function?

[OrangePulp]

Is there any pad plugin out there that allows you to set buttons to turbo? Alternatively, does anyone know of a way to add turbo after the fact to my PSX-USB adaptor (I'm actually using a dualshock 2 with it)? I'm looking to be able to tape down buttons and farm in rpgs at 900 fps (with frame limiter turned off).

So after doing some searching, it looks like there isn't any plugin which supports this. Anyone got a line on a USB gamepad driver that does?

So I found a solution, sort of. I'm using JoyToKey to map the circle button to J, and setting it for autofire, and then mapping J to circle in ePSXe.
