Hi people of Gbatemp. Thanks for reading this topic. I think I have found a possible floor of exploiting. Do you remember about a few of years ago Nintendo released TLOZ (legend of zelda) Four Sword? Well,it has been released free. So,I mean,it was encrypted with the common key or (maybe) with nothing! I haven't the necessary skill,but someone can test some hack/exploit?? I've a Dsi FW 1.4.3E if necessary for testing,feel free to contact me in pm. It's possible a thing about that? Nobody (I seen,I check out Google too) thinked about it. Please answer me ASAP.
