AETools version 3 is a multi-purpose tool.

Features

* Extract and convert a number of binary data types such as ONCC, ONWC, M3GM, TXMP, TRAM and many more.
* Create a package for the Anniversary Edition.
* Utilities and tools for the advanced users.

To install, simply place the enclosed application and the AETools_Data folder inside your Oni/Edition folder.

Once you have the Edition installed, AETools will find the copy of OniSplit.exe that comes with the package and you can use it to export and import files, as well as to rebuild any level's data folder or to create plug-in mods. The application has an article on the wiki here.
