Fate/Extra

[Kami_no_Kage]

I think I've now solved the problem. You can't use an encrypted iso to play this, and the new iso I'm using is the US release, so maybe that works best. Looks just a tiny bit better too.

I can now speak with my servant using the different iso, gonna see if I can grind and then leave in the dungeon. Although no one has helped me here, hope maybe this helps someone else.

Edit: I can now leave the dungeon, even after I've made level 4. It seems I was right and the moment you can't leave is when your servant's after fight messages stick on the screen, because they didn't for me this time around. So in conclusion, if you cannot the first dungeon and/or cannot speak with your servant, it is the iso's fault. Try to get the US version iso, and make sure it is not an encrypted iso.
