Can you be more specific about what part of the game you're at?
This is where it consistently hangs on my system. (Please excuse the picture quality, as photos of CRTs will tend to look this way.) The audio endlessly repeats the last fraction of a second.
As it might matter, I'll mention that I'm using a prepatched image, as the patching instructions involve the Windows-only ISOBuster, and I've found Windows programs to be really dodgy on Linux. I could try borrowing a Windows machine to patch it myself, but it did play all the way up to this point... Strange that anything should go wrong so late in the game. I've had loading issues happen before with the Fenrir, but never at a consistent point.
