But the games have never officially been released in English and I don’t know if it’s even possible to buy them outside Japan. AFAIK most English speakers download a torrent which contains a pirated version of the disk images plus a tool to automatically patch in the English text. If you can manage to buy the Japanese version you can also find and install the translation patch separately, but IIRC the translation patch is only compatible with the older version, not the version that was remade for better Windows 7 compatibility.
Where/how can one buy this thing?
There’s an online store with various versions of the game and spinoffs: http://www.age-soft.co.jp/dlstore/
