What's the 2004 'old' version?

What's the 2013 '07scripts' version?
The 07scripts version is a customized map setup of what both the 2004 and the 2007/05/15 custom maps would bring, except it is more visual and interactive. The code for this particular generator was cleaned up for offline use. It also went offline on April 2014, so this and the cwcyrix site will be the only location for this script so far.
