I COMPLETELY forgot to add an important READ ME document in my torrent.

If you start to play the original game, you’ll probably find that you can’t see any of the text. It’s a bug, but it’s easy enough to fix. Just go to your Succubus Quest game folder, find the Game.ini file and open it with a text editor. In the second line “Library=RGSS102J.dll”, change “102” to “103”. Save, test your game. If all works well, that should solve your problem.
