I'm having problems with the TNC gallery not unlocking. I've finished Gunji, Kiriwar, and Arbitro's routes and even after sitting through the credits the option for the gallery isn't unlocking in the title screen. I thought since Gunji and Kiriwar's routes are just extra and not one of the 4 main routes they didn't count to unlocking it (as I did them first), but after just finishing Arbitro's routes nothings happening. Do I need to finish all 4 of the main routes/all of the routes for it to unlock or is my copy messed up???
