My bro wants me to install arm9loaderhax onto his 3ds, but his 3DS is 10.7. So I'm going to have to downgrade his 3DS to 9.2, but browserhax doesn't seem to work. Is it possible to inject cubic ninja into a different game cart? Like if I took my physical copy of MK7 and a rom of Cubic Ninja, could I merge the two together?
