SMWiki, SMW Central's Wiki and coined as "Your secondary SMW hacking resource", is a supplementary Super Mario World information database to SMW Central that can be reviewed and changed by anyone. Hence it being a wiki.
Originally set up on SMW Central on April 14, 2007, the SMWiki was a thriving database that was continuously being added to, until the server move, in which Kieran, aka Boom.dk, had to leave the SMWiki behind. His subscription ended March 1st, 2009, taking the Wiki down with it. Luckily, just earlier on January 4, 2009, andy_k_250 had created a downloadable backup, which was hosted online several months later by Ultimaximus. This archive was linked to on the forums as a pseudo-replacement, until the Wiki was revived on November 22, 2009.
Since then, the Wiki has been in the process of restoration, transferring the content manually from Ulti's Wiki.
