There are a few possible cribs, but individual words aren't enough. I even had a medieval disk once that (with a lot of interpretation) might have matched two VMS disks, but of course that didn't get me any further either. We definitely need more than just individual words—we need whole sentences! Simply because, if there’s a language behind it, it certainly can’t be a substitution; it must be something much more complex. And individual words wouldn’t help in that case.
Example: I’m pretty sure there’s an image of ivy at the bottom of f99r; it has a label: tolsasy - so now what?
