From what I can tell, they have:
Sega Ages Vol. 32 (Operation Moon Gate)
Playstation MARZ guidebook (white cover showing Temjin)
MARZ guidebook #3 (blue and white cover)
Operation Moongate book (group shot of the Virtuaroids on the cover)
And they have something that looks somewhat similar to the Wall of Truth, although it's cover is slightly different, so it's probably something else. It's "Cybertroopers Virtual-On Oratorio Tangram Shinjitsu no Kabe Art Book". They also have some other books and various VO CDs, plus a SD OT Hyper Fei-Yen figure, which appears to be a limited edition item. Plus, various copies of VOOM (with one of them being for Seganet) and a copy of VOOT, DC Twinsticks, and an OMG Arcade Machine, although good luck in getting that.
And, because people are looking for it. OMR, or at least what I was told is it. It's translated and up on the net. Unfortunately, it's not all there, but at least it's some of it. It's missing both parts of Chapter 8, it seems.

You have to highlight the text on the chapter pages for some odd reason, but don't worry, it's there.
