currently only combine ROM's, edit text strings, and edit
Sonic 3 special stages. However, it is said that it will
be able to do a lot of other things. This will not only
combine ROM's to make S1K, S2K, S3K, etc, but it will
even 'repair' the Sonic & Knuckles 'dirty' ROM's. As
for text editing, it allows editing the Sonic 1, 2, 3,
and K/3K level select text and enabling and disabling

several other things as well. This is a must get utility.

shortcut bar to run your favorite hacking or emulation
tools, as well as a SonED launcher so you don't have to
