I have fairly limited experience with emulators. Is it possible to improve file loading times in them, or is loading always limited by how the system handles its file system? That's one thing I'm concerned about with certain Wii U games (like the upcoming Tokyo Mirage Sessions... I preordered it, but seeing people list the load times in that thread makes me wonder if I'm in for a world of black screen pain and I should just wait and rip from my disc instead)
