You can't be sure you won't be waiting a while. Decrypt9 is just as easy to use (technically a bit easier since there's no real interfacing at all, just run, hit A, and wait, then shut off the system.) You just have to reset your Cubic Ninja exploit is all. (You're not using Zelda OoT are you? That one is a lot trickier, but I believe Smealum was working on supporting it with Ninjhax 2.0. I'm not sure if you can run decrypt9 in Ninjhax 2.0 however... You may need 1.x.)
