Atelier Meruru: The Apprentice of Arland [BLES01593]

Since you have a much faster computer than me try starting a new game a few times and see if you get anything. I suspect that Ayesha just has the exact same black screen of death bug as the other Ateliers and Ar Tonelico 3, and it seems random when they hang. If it's a thread synchronization issue it might work better (or worse) for you.

The furthest I can reach is this intro scene were the camera just pans until you stop the emulation, similar to what happens randomly, at least to me, with Totori.

Is it the same problem Ar tonelico has when the text boxes of dialogue just stop showing, a character loops its animation endlessly or the screen just goes black?

As said, it seems like the exact same issue. And also, you got further than me. I have never actually seen any in game graphics in Ayesha. Maybe you got lucky, or maybe a faster CPU helps... I hope this is a bug in the emulator, but it could also be a bug in the game where some threads hangs because everything is running so slow, aka a deadlock.
