3DS:Splash screens

+

Splash screens are images that can be displayed on the top and bottom screen during startup. You could use these images to, for example:

Remind you of key combinations (e.g. hold SELECT for Luma3DS configuration, hold START for Luma3DS chainloader)
Display a commemorative BIOS screen

Splash screens are static images. If you want to see an animation on boot-up instead, check out 3DS:Boot animations.

Anemone3DS instructions

Splash screens do not display during the boot process, they interrupt it. For instance, if you have a splash screen that last three seconds, your boot time will be increased by three seconds.

Enabling splash screens

In order for splash screens to be displayed, they must be enabled from Luma3DS configuration. You'll only need to do this once (unless your configuration file is reset).

If you have a PIN enabled, the splash screen will be displayed after you enter your PIN.

Power off your device
Press and hold (Select), and while holding (Select), power on your device to enter the Luma3DS configuration menu
Scroll down to Splash and press (A) until you see (x) to the right of Before
- You could also set it to After, but that would make payloads inaccessible from the splash screen which would lessen the usefulness of the splash screen

By default, the splash screen will last 3000 milliseconds (3 seconds). If you wish to extend or shorten this time, modify the splash_duration_ms line in the file config.ini (inside the luma folder.

Creating a splash screen

If you want to put your graphic designer passion into use, you can create your own splash screen. This process can be generally simplified with the splash-ds web tool, but the gist is:

Create your images with an image editor of your choice
- You probably want to use JPG files since the 3DS probably isn't going to handle transparency very well
- The top screen must be 400x240 px and the bottom screen must be 320x240 px
Open the splash-ds website
Drag-and-drop your images into the website, and play with the settings as you see fit
Click "Download splash screen"
Open the resulting .zip file that the splash screen is inside of
Put your SD card into your computer
Extract splash.bin and splashbottom.bin to the luma folder on your SD card
Put your SD card back into your 3DS
