  • Re-added splash duration setting option in configuration menu (custom values also supported)

For detailed technical information, please refer to the official Luma3DS documentation and README.

Installation

Nexus3DS requires boot9strap to run.

Once boot9strap has been installed, simply download the latest boot.firm file from the releases page and place it on the root of your SD card to "install" or upgrade Nexus3DS. Replace any existing boot.firm file if necessary.

Limitation

CTGP7, does not, and never will, work with Nexus3DS. As a workaround, you can use Luma's Firm Payload Chainloader feature to be able to quickly choose to boot between Nexus3DS and Luma3DS depending of your needs. The best way would be to use Fastboot3DS allowing you to configure the boot order, buttons and such.
