The codes for WWE SmackDown! Shut Your Mouth up to WWE SmackDown! vs. RAW were done on ProBoards (the old Code-X forum
). Sometime in like 2005 or 2006, Code-X moved to it's current forum (Invasion Power Board) and codes from WWE SmackDown! vs. RAW 2006 onwards were done on this site. With the ProBoards version of Code-X not being active in like 7 years, I guess the codes have been lost.
I'm not 100% about all that as I joined the Invasion Power Board version of Code-X after the move but it seems to me that is what has happened. Unless you can get in contact with one of the Moderators or Staff from ProBoards era (which they might be hard to get hold of), I don't think the codes were posted on the Invasion Power Board verison of Code-X (this site), only linked to the old one (which are now broken).
If I'm wrong on anything said above, anyone please feel free to correct it but with so little members here, that's all we have to go on. If I find any information out I will pass it on.
