两种方法都需要两台设备。 One 3DS (or 2DS) must be running some kind of custom firmware (such as boot9strap or arm9loaderhax) and is referred to as the *source 3DS*, while the other 3DS (or 2DS) is on stock 11.6.0 and referred to as the *target 3DS*.
Both of these methods require you to [System Transfer](http://en-americas-support.nintendo.com/app/answers/detail/a_id/13996/) from a CFW 3DS to a stock 3DS as part of the steps. System Transfers will work in the following directions *only*:
In both of these methods, the source 3DS's NNID will be stuck on the target 3DS unless you either system transfer back or call Nintendo (details can be found in the instructions)! System Transfers can only be performed once a week per NNID.
This method requires that the source 3DS buys or already legitimately owns one of the games listed on the [Installing boot9strap (DSiWare Game Injection List)](installing-boot9strap-(dsiware-game-injection-list)) page.
