So I've been burning through Muramasa: The Demon Blade recently, and after I got the blade to break light blue barriers and proceeding through Shinano Prefecture my screen went black and in white letters "暫く御待ち姥" flashes. Any idea what it is and/or how to fix it? Maybe translate it? I'm playing the English US version using no cheats and I haven't altered any code or anything.
Here's a screenshot of the emulator when it happens.
