Important
There are far superior ways of handling this now, with built-in functionality in for example the excellent Tesla replacement https://github.com/ppkantorski/Ultrahand-Overlay. Archiving this :)
This project is a fork of NRO Asset Editor, all credit goes toward them.
I needed a way to edit assets inside of .ovl files aswell as .nro files, because sometimes I get annoyed with the strange versioning some homebrew or sysmodules have, and the way they are then visualised in for e.g. Tesla Overlay. My brain likes conformity.
I decided to move from tkinter, because I could. In any case, like I stated. Any and all credit goes towards the dev of the original tool. I don't know what's customary when it comes to stuff like this, original LICENSE is provided.
To run the GUI, either run the precompiled binary from the release page, or run maker.py without any additional arguments.
