It does not support XInput (R2/L2 mapping on any XInput controller such as XBox 360), but FF7Steam has an additional bug where it doesn't map some buttons such as the directional pad on XBox 360 controllers. It seems like a button range bug of some kind. FF8Steam, for example, does not suffer from this and lacks XInput support as well.
I'm just not sure how to put all the above in a pithy sentence.
