Custom Banners for USB Loader GX

This is a guide on how I was able to make custom banners for use in USB Loader GX. While it may not be the best way to do it, it is the one that I found to work. If you happened to have found a better method, ping me on the RiiConnect24 Discord server, my username is Snare-Hawk#6331.

What you need

CustomizeMii
A WAD to use as a base, such as this Animal Crossing one
An image editing software, such as GIMP

Optional

An audio editing software, such as Dark Audacity

Instructions

Find or create a fitting image that you want to use as the banner art.

For a good banner, I recommend just putting the game's logo on top of the title's art in your editing software.
For best results, ensure the image's aspect ratio is 16:9.

Compress the image as much as you can.

I've noticed that the larger the WAD is in size, the longer it takes to load in your USB loader.
I recommend using TinyPNG.

Launch CustomizeMii and open your base WAD.
Select the "Banner" tab and then select "MenuScreen.tpl". Then select "Replace" and choose the image you want the banner to have.

If you want to add your own music, select the "Options" tab, select "Browse" under "New Sound" and then "Load Audio File".
Your audio file must be in .wav format and for best results, it should also have only one audio channel and be under at 15 seconds.

Select "Create WAD" and save your WAD to your desired location.
Open your new WAD in CustomizeMii and select the "Options" tab, select "Extract..." and then "WAD Contents". This will extract the WAD's content to a folder to your desired location.
Locate the folder containing the WAD contents and then rename the file named 00000000.app to [GAME ID].bnr.
- You only need to have the first three characters of the game ID for USB Loader GX to read it properly.
Place your banner file in apps\usbloader_gx\cache_bnr on your SD card.

You should now see the banners you created with their respective title. If you would like to see the banners I have made, check them out here.
