Decrypt & Unpack / Rebuild 3DS and CIA Files In this short guide we'll address decrypting, unpacking and repacking a legit CIA for editing purposes. Requirements Legit CIA or 3DS Package/ROM - Get on "That ISO Site" PackHack / PackEnglishV5.3.rar - http://pastebin.com/A1s8cmsD Decrypt9WIP - https://github.com/d0k3/Decrypt9WIP/releases Extract PackEnglishV5.3 into a folder and merge the two directories inside of it so the applications and keys are in the same directory/folder. Create a directory on your SD Card named \D9Game\ and upload your CIA/3DS file into it. FOR CIA FILES Run Decrypt9WIP and pick "Content Decryptor Options" Then pick "CIA Decryptor (deep)" Finally wait for the progress screen to complete FOR 3DS FILES Run Decrypt9WIP and Pick "NCCH/NCSD Decryptor" Finally wait for the progress screen to complete Copy the now decrypted CIA/3DS from \D9Game\ to the folder you extracted PackHack to and run HackingToolKit. For CIA type in "CE" or for "3DS" type in "D" and then press "enter" Type in the Filename and press "enter" and type in "n" when it asks to "Decompress The Code.bin file". If all goes well it will extract the contents of your CIA/3DS file. You'll know it went well if there is now both "ExtractedExeFS" and "ExtractedRomFS" folders in the folder you put PackHack in. To repack the CIA/3DS run HackingToolKit and type in "CR" (for CIA) or "R" for (3DS), type in a filename and press "enter". That's all she wrote!
