SonLVL (formerly known as S2LVL) is a utility for editing levels in the 16-bit versions of Sonic 1, Sonic 2, Sonic 3 & Knuckles, Sonic & Knuckles Collection and the Mega-CD and 1995 PC versions of Sonic CD. It was written by MainMemory in C#, and requires the .NET Framework 4.5.2 to run. It was created to offer an alternative to SonED2. Project files for several disassemblies are included in the Updater program linked below. It has a repository on Sonic Retro's GitHub, so that anybody may obtain the source code and make changes.
If you're having trouble setting it up, check out SCHG How-to:Set Up SonLVL.
A changelog for the GitHub revisions can be found here.
