UPDATE - this cool guy called 'Collector' from some (cool) GK forums made a much better installer for the patch.
It now works with the Hendroz installer (another user made patch to let you install the full game on your drive, the subtitle patch wasn't compatible with that before), AND the deinterlacing patch as well.
In addition to that, it now also works with the DOS version of the game.
