I don't know how he is working, but I would guess it could take a while. Spurs is massive, and work only began 1-2 weeks ago or so, looking at the wiki, and IIRC.
Yes, I'm still working on this and it will take a while to get some decent results. Right now I'm improving the decompression algorithm for EDAT/SDAT. When I'm done with that I'll move back to SPURS.
I already have a few more drafts for functions which I'll be committing after some internal testing.
