This was a joint effort by myself and Himeros. Himeros was working on a decensored patch for the the game and asked for my help so I did the decensoring and he did the work on the patch. For people who just want the CGs you can download them below.
CG images only
CG images only mirrior incase the first link does not work
For the patch you can download it here.
That being said the patch only works if you have the game.
Getting the full version of Fate/Stay Night isn't exactly easy - the English installer is designed to only work with legal copies of the game, which are normally only sold in Japan.
Amazon sells the legal game at a rather ridiculous price.
However, assuming someone owns a legal version of the game, they can get the English installer for free at http://mirrormoon.org/
Of course, it is possible to get the game illegally via torrents and at the $130 price tag for a such an old game I would not blame people either for doing so but neither me nor Himeros have tested the patch on such copies.
If you have questions regarding the patch you can contact Himeros at Himeros email
