So I've played School Days through the first five chapters, for which there are Chinese translation patch available.
5.0 | 5.1
The translation patch is flawless in my opinion. Some screenshots of the game with patch applied:

So in order to get through the last chapter, I was following the story guide written by other people, and it works well.
(Partly also because I am Chinese and can usually get the gist of the meaning of sentences by looking at Kanji (Chinese characters) and listening for simple phrases I know)
But then I saw the tool ATGH, which can capture the texts being displayed in J-Games.
Most people use the tool with ATLAS to translate the text into English, automatically through clipboard monitoring.
But there's not any automation tools that works with Japanese-Chinese translator, so I wrote an AutoIt script that does this automatically.
The translator I use is cracked j.Beijing v6, which I must say really impresses me for a machine translator.
It's made by KODENSHA, you can try it out online here.
Here's a screenshot of the automation in the works:

Now I can also play Summer Days, which is an alternate universe prequel to School Days, with automatic Chinese translation.
