SonED 2 is the primary Sonic the Hedgehog editor, working with Sonic 1 and Sonic 2; however, it requires that the game be prepared to produce a "split disassembly", where the level art, level layouts, object definitions etc. are split from the actual assembly code into separate data files. Work now goes into commenting the code such that it can be worked on.

The current most popular split disassembly for Sonic 2 is not maintained, but was created by Nemesis; it uses SNASM68K for assembly. A more technically advanced split disassembly was created by Aurochs (although he no longer maintains it) and uses Alfred Arnold's AS for assembly.

ESE2 is another popular level editor, working with Sonic 1, Sonic 2(its beta too), and Sonic 3k, its tools include a Layout editor, a Palette editor (a very good one), an Object editor, and a tile editor. I recommend using this as your main editor, but yet SonED does have some special quality's as in seeing the sky in the layout editor, and other useful things, if these two apps are used properly together they can produce some pretty good maps!

So very stubbly.
This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?
