So I recently discovered & got this neat PC controller support app & got it really cheap ($1.50) on Steam's holiday sale. It's very intuitive, has a nice interface & easy to set-up. Has controller support even for the desktop too, so it's like having remote contol for the PC (no more getting off the couch!) Xpadder & joy2key are known to be more popular so I'm sharing this info as some may be interested in an alternative. Can finally play KOTOR 1 with a gamepad.
@Boodaliboo KOTOR 2 already has integrated controller support with it's latest update, only KOTOR 1 needs this.. but Controller Companion is indeed a good purchase. It also works good with other games with no controller support, like TES Oblivion. It's on steam & seems to have good support from it's developer which constantly updates it.
