MEK

The Mozz Editing Kit, previously called the Moses Editing Kit or Mo's Editing Kit (MEK), is an open source and cross-platform Python-based toolset which offers alternatives to and supplements the tools of the HEK.

Being pre-MCC, it only supports Custom Edition and should not be used with MCC tags. However, unlike invader it does support OpenSauce tags.

The MEK is still used for some of its unique features:

Map deprotection.
Exporting and importing tag blocks, saving time when copying data across tags.

The MEK project unmaintained and has known issues. Consider using alternatives like Invader and the updated H1A-EK for MCC.
