Luma3DS

Noob-proof (N)3DS "Custom Firmware"

What it is

Luma3DS is a program to patch the system software of (New) Nintendo 3DS handheld consoles "on the fly", adding features (such as per-game language settings and debugging capabilities for developers) and removing restrictions enforced by Nintendo (such as the region lock).
It also allows you to run unauthorized ("homebrew") content by removing signature checks.
To use it, you will need a console capable of running homebrew software on the ARM9 processor. We recommend Plailect's guide for details on how to get your system ready.

Since Luma3DS v8.0, Luma3DS has its own in-game menu, triggerable by L+Down+Select (see the release notes).
