I have here an unknown binary file which contains a graphical user interface. The file has the ending .kzb and it comes from the Kanzi desinger. Unfortunately the Kanzi desinger can no longer edit the extracted binary file. Apparently you can only change something if you have the original project. The file contains pictures that I would like to change. I know that it has to work, because someone has already done it, but doesn't want to reveal the secret :) Here is the file I want to customize. https://drive.google.com/drive/folders/1Z-RCdVGJv_jkKHcL3o_saOZz8sluMMG1?usp=sharing In the file is a Chinese and an English flag (as .png) which I would like to change / swap.
