Be careful. I played thirty hours into that game recently and then my save data got corrupted and I had to start over. Apparently it's a fairly common problem. Back up your saves to another device frequently or it'll break your heart.
And I just got Yukari to start dating me...goshdangit.
Is this a problem with the emulator or the actual game? I never had any problems and I have like 12 saves for 3 different play throughs to make sure I dont get F'ed by doing something stupid.. also I forgot where I was when I randomly stop playing for long periods of time and dont feel like deleting something with at 50+ hours in it.
