Welcome MetConstians to the Metroid Construction Documentation Wiki, the ultimate resource for all things Metroid hacking related! This wiki holds the collective knowledge of MetConst, documenting all discoveries and information about hacking Metroid, written by you guys for the benefit of all MetConstians everywhere! We have guides ranging from basic FAQ's to advanced assembly guides, it's all here! If you are looking to get started editing this wiki, check out the syntax page to learn how to edit, or check out any pages source code. You can also use the playground to test any editing you do.

This wiki is paired up with the WikiTalk Board, please document any work you do on the wiki to this forum board so that we can keep track of new pages and edits to existing pages. It also helps other people assist you and others when working on the same document.

Currently the wiki is undergoing a lot of work, so a lot of documents might not have made it to the wiki yet. If you want, you can help out by filling out some backlogged information and data to the wiki, and searching the forum for any lost information that should be preserved in here.
