Unofficial Patches
It's also come to my attention that others are attempting to compile SEEN.TXT builds. These are unofficial and will be unsupported by the project. There are many hacks that have been implemented into the game that will crash in these builds, plus they are not using styling, nor are they using working executables that are guaranteed to work correctly. ANY REQUESTS FOR SUPPORT ON THESE UNOFFICIAL BUILDS WILL BE IGNORED.
Die bestehenden Englisch-Patchs lassen sich mittels Google ziemlich schnell finden...

How to Install?
Just replace your seen.txt inside Clannad's installation folder with the new one.
