I don't have any vibrations in PlayStation games on ePSXe with XBox 360 Controller (wired).
ePSXe version: 1.7.0
System: Vista 32-bit SP2
Games tried: Front Mission 3, Medievil (those two had vibrations on my previous pad)
ePSXe gamepad settings:
Spoiler warning:
Do I need some special drivers or fix?
