Well, this method of generating the files has failed, just like the other combinations I've tried. I generated ncchinfo.bin with the ncchinfo_gen.py script from the newest version of Decrypt9, copied it and my slot0x25KeyX.bin file to the root of the mSD. Then I copied the Decrypt9 folder containing the Decrypt9.3dsx and Decrypt9.smdh files to [root]\3ds\Decrypt9 and the Launcher.dat and Decrypt9.bin files to the root of the mSD. I ran Decrypt9 via Ninjhax 1.1b and it failed to generate the files. The two primary errors would seem to be "Could not open seeddb.bin!" and "Too many/few entries in ncchinfo.bin".
