Yeah, there are definitely reasons for using a crack with this game other than piracy. The only way to play KotOR 2 at widescreen resolutions higher than 1280x768 is with a crack. Sorry, but you'll just have to use that external drive.

Fix their home team score on the board to the debt clock, they can win every game 17,000,000,000,000 to 24. Losing team gets taxed by the IRS 100%, then droned."
