If I'm not wrong is official patch without protection only need dvd mount.
You can still use latest patch 1.06s.
The patch s is to bypass the serial protection for legally bought game user who still having problem launching the game.

You need winrar 5.0+ to extract the save. You need to fill the bar the quickest to see their scene. Almost all girls you can unlock their scene by only using hand mode focusing in their boob.
This game has additional patch here Yuugi Kyouka Hen. It still need crack though. When the crack is release you can update to 1.08 and apply this.
Additional information in 2014-12-05 there is gonna release a new patch Yuugi Kyouka Hen 2.
