#### Main source code:



- [Sonic-Clean-Engine-S.C.E.-](https://github.com/TheBlad768/Sonic-Clean-Engine-S.C.E.-)



## Quick start



- For editing sprites you can use [SonMapEd](https://info.sonicretro.org/SonMapEd), [ClownMapEd](https://info.sonicretro.org/ClownMapEd) or [Flex2](https://info.sonicretro.org/Flex_2) (Read the issues).



- For editing levels you can use official [SonLVL](https://info.sonicretro.org/SonLVL) or [SonLVL-64x64-Compatible](https://github.com/Project1114/SonLVL-64x64-Compatible). Unfortunately, [SonED2](https://info.sonicretro.org/SonED2) is no longer supported.



- To convert SMPS music to asm format you can use [smps2asm](https://forums.sonicretro.org/index.php?threads/smps2asm-and-improved-s-k-driver.26876).



## Current issues



1. S.C.E. uses [Kosinski Plus algorithm](https://github.com/flamewing/mdcomp/blob/master/src/asm/KosinskiPlus.asm), but **Flex2** program does not support **Kosinski Plus Module**. Therefore, **Flex2.json** project file is partially useless. **SonMapEd** program does not support **Kosinski Plus** at all. You can only open uncompressed graphics.



#### Alternative programs:

- [mdcomp](https://github.com/flamewing/mdcomp/releases)

- [ClownMapEd](https://github.com/Clownacy/ClownMapEd/releases)

- [FW-KENSC-ShellExt](https://github.com/MainMemory/FW-KENSC-ShellExt/releases)



2. S.C.E. uses a different layout format to support two-byte IDs chunks. Unfortunately there are no converters here for the new layout format. You just won't be able to use the original layouts from Sonic 3 & Knuckles.

You could try using different [Layout.cs](https://github.com/TheBlad768/Sonic-Clean-Engine-S.C.E.-/tree/master/SonLVL%20INI%20Files/Common/Layout) for **SonLVL** to convert layout to the new format.
