Suzumiya Haruhi no Tomadoi (special edition, if that makes a difference)

Since Suzumiya Haruhi no Tsuisou is coming out in a few months, asking this now would be good (since I'll probably not play Tomadoi again once Tsuisou comes out).

Anyway, are there any codes out there for this game (it's for the PS2)? It's a pseudo-visual novel where you have to build your own game (which, depending on how you play the VN part, can turn out to be anything from an 8-bit FF-esque game to a 3D one)

I've had Tomadoi for a while, but haven't unlocked much (and I've yet to find any walkthrough for it) (or, at least, any walkthrough that makes sense) (and I cant read Kanji... I can read Kana, but I cant translate it, so that's pointless), and I was wondering if there was a code that'd unlock all the special content in the game.
