SonLVL

File:S2LVL.png

The main window in object/ring editing mode.

SonLVL is a utility for editing levels in the 16-bit versions of Sonic 1, Sonic 2, Sonic 3 & Knuckles, Sonic & Knuckles Collection and the PC version of Sonic CD. It was written by MainMemory in C#, and requires the .NET Framework 3.5 to run. It was created to offer an alternative to SonED2. It is compatible with the SVN disassemblies of Sonic 1 and 2. Betas 1-4 also included INI files for Xenowhirl's 2007 disassembly of Sonic 2, and Beta 4 includes INI files for User:Hivebrain's 2005 disassembly of Sonic 1. It is now part of the Community SVN Project, so that anybody may obtain the source code and make changes.
