So, I'm making a mod of an open source homebrew app and trying to compile it from source code. I want it to display a custom image and audio in the banner that shows when hovering over the app in the home menu. I noticed that after compiling the app, however, that the audio was still the same as the original app and the image file was also the same, although the app icon, name, and author were changed to what they were in the source code. So, I figured that the banner.bnr file was where the audio and image came from, and I tried to find a tool to edit it but the download link seems to be broken. So, I want to know which tools I need and how to edit the banner.bnr so I can customize it.
