I've downloaded OpenSSL and obtained my Wii SD-key and SD-iv for unpacking, and I use the correct parameters for OpenSSL's AES-128-CBC tool. It decrypts it correctly, but at the end, it throws an error. Regardless of how much I actually decrypt(even if it is one byte) What is the problem? The file in question is data.bin. I just want to be able to run some user created scripts on Black Ops Wii to have some fun, modded games. I've already done it via ISO hacking, but some files are replaced by the patch(the gungame scripts) and I can't edit those. Besides, I hate burning discs when I want to make a new mod. I'm not sure if this is against the rules or not. I don't think so, because I'm not distributing anything and the Black Ops patch is free.
