BootNTR 3DS

BootNTR is a 3DS homebrew application that allows you to run NTR CFW on your 3DS.

NTR CFW is a custom firmware designed for New 3DS. With NTR CFW, you have a wide range of options like cheatmenus, streaming (no capturecard required) and a lot more. It's also plugin friendly. In order to use the features on your 3DS, the custom firmware will need to be launched manually before activated.

NTR CFW is the successor of NTR 2.2 (legacy, only works on new3ds and is not compatible with Emunand) with added supports for old3DS as well as 2DS. This application is not depending on your CFW you are running and need to have support for the firmware.

Note: It is suggested to use BootNTR Selector instead, which has higher compability and faster updates than the original.
