I just got an in-game unlock that I haven't seen documented before, not even for PS2, though I'm guessing it's there.
What I got was the Beyond Mode option "Immortal," which obviously lets you play any Beyond Mode stage without worrying about taking damage. I can't tell you what unlocks it though, because I did a number of things for the first time all at once. I got a local ranking of first on Direct Assault, completed Direct Assault without using Infinity Overdrive, and completed Direct Assault (trance). It could have been any or all of those things that caused the unlock.
Edit: it was completing Direct Assault (trance). Says so in the post-unlock version of the "Trance Hacker" achievement description.
