**Luma3DS** is a program to patch the system software of (New) Nintendo (2)3DS handheld consoles "on the fly", adding features such as per-game language settings, debugging capabilities for developers, and removing restrictions enforced by Nintendo such as the region lock.
To use it, you will need a console capable of running homebrew software on the Arm9 processor. We recommend [Plailect's guide](https://3ds.hacks.guide/) for details on how to get your system ready.
Since v8.0, Luma3DS has its own in-game menu, triggerable by <kbd>L+Down+Select</kbd> (see the [release notes](https://github.com/AuroraWright/Luma3DS/releases/tag/v8.0)).
