Background

My first time purchasing games on dmm.co.jp (or FANZA), having experienced the confusing download page(it told me to use Browser’s Save Link As because Chrome doesn’t support dmm downloader) , I extracted game files from 3 separately downloaded rar part.

(No Photo)

There’s one README.txt(filename is in Japanese) and one game folder in extracted folder.

(No Photo)

Fine, the main program must be xxx.exe…

A dialog textbox throwed, as I opened tha main program, I can read Chinese character (or Kanji) , knowing it’s something my PC lack to run the game. And installed SoftDenchi with clicking OK at all.

I submitted my dmm.co.jp user ID and password in first launch.

The problem is, I need to use textractor to read scripts from the game, and translate it to English in read time.
However, there were three independent process for one game.

• koikake.exe
• koikake.bin
• koikake.exe
