The contents of a CIA file can be extracted with the help of various hacking tools, and then decrypted for use with Citra, an open source emulator. In this guide, we will explore the steps required for decrypting CIA files for use in Citra.
Understanding Hacking Tools Required to Decrypt CIAs
In order to decrypt CIA files, we need to first obtain the necessary applications and software versions that will allow us to do this. The most commonly used tools for this purpose are: GodMode9, Decrypt9WIP, GMXDumpTool, ctrtool, and Gateway 3DS/Sky3DS+. All these programs have their own unique functions which we will discuss in detail later.
Installation Guide For All Hacking Tools Required To Decrypt CIAs
Once you have obtained all the required applications and software versions necessary to decrypt CIA files, the next step is downloading and installing them on your computer or device. After installation is complete, it is important to test each program individually to ensure that they are running correctly before proceeding further.
Dumping Game Cartridges Via Gateway 3DS/Sky3DS+ Cartridge
The Gateway 3DS/Sky3DS+ cartridge is a device used to dump game cartridges into ROM files which can be used with various hacking tools such as GMXDumpTool or ctrtool. The ROM file structure consists of several parts such as a header area which contains information about the game itself (title ID, region code etc.) along with encrypted data blocks which contain the actual game data. To dump a cartridge with the Gateway 3DS/Sky3DS+, you simply insert your cartridge into the device and then follow the instructions provided in its user manual.
Understanding The Process Of Extracting CIAs From ROMs With A Tool Called GMXDumpTool
GMXDumpTool is a powerful tool used for extracting CIA files from ROMs created from dumped cartridges using Gateway 3DS/Sky3DS+. This tool has several features including auto-decryption of encrypted data blocks contained within a ROM file and also supports multiple regions when extracting CIAs from different regions’ games. To extract CIAs from your ROM file using GMXDumpTool, simply open up the program and follow its instructions on how to do so.
Overview of GodMode9
GodMode9 is a powerful file system browser for the Nintendo 3DS console. It can be used to mount and decrypt CIA files, which contain game data. It can also be used to browse the contents of your SD card, transfer files between your PC and 3DS, as well as other useful functions. The most common use for GodMode9 is to decrypt CIA files so that they can be used with Citra, a Nintendo 3DS emulator. Decrypting a CIA file with GodMode9 is relatively straightforward; all you need is the file itself and a copy of GodMode9 installed on your device.
Compactable Process with GodMode9
Once you have obtained a copy of GodMode9, the first step is to navigate to the folder containing the CIA file on your SD card or flashcart. After selecting the file, press (A) to open it in GodMode9. Once opened, navigate to [C:] GAMECART and select the option Extract entire gamecart image (Decrypted) at the bottom of the menu. This will begin the process of extracting and decrypting the contents of the CIA file into an extracted folder on your device’s SD card or flashcart.
Using GodMode9 To Mount Your Newly Generated CIA File
Once you have extracted and decrypted the contents of your CIA file with GodMode9, you will need to mount it in order for it to be playable on Citra. To do this, open up GodMode9 again and navigate back to [C:] GAMECART in order to select Mount image as virtual drive from within this folder again. You should then see a new entry appear in [G:] VIRTUAL DISK with your newly generated ROM ready for play.
Explanation Of The Mounting Process
Mounting a ROM through GodMode9 allows it to be accessed by applications such as Citra without needing to physically move any files around or modify any data structures within them; essentially allowing you to play games without needing any additional hardware or software modifications outside of whats already available on your device itself! The mounting process involves creating a virtual drive that acts as an interface between your device’s operating system (such as ctrtool) and applications such as Citra by making them think that they are accessing physical locations instead of virtual ones; making it possible for games from different regions or formats (such as .3ds/.cia) to be playable without any extra effort required other than whats necessary when decrypting them with GodMode9 in the first place!
Sample Output To Verify The Successful Mounting Of The File
Once mounted correctly, you should see something similar to this in [G:] VIRTUAL DISK depending on which type of ROM was being mounted:
– For .3ds ROMs: “GAME_NAME_V1_x_x” – For .cia ROMs: “GAME_NAME_V1_(region)” – For EShop/retail ROMs: “GAME_TITLE” – For VC/WWW ROMs: “VC_GAME_TITLE” – For DLC/Updates/Patches etc.: “DLC_(region)” If you don’t see anything like these entries after mounting then there may have been an error during extraction or decryption; so make sure everything was done correctly before continuing further!
Overview Of ctrtool
ctrtool is another useful tool for working with decrypted Nintendo 3DS game files; specifically those related to Citra emulation such as .cia/.3ds ROMs or even EShop/retail dump formats. It can be used for extracting data from these types of files, converting them into more manageable formats such as .nds/.ndi/.ncch etc., patching them using xorpad customization tools like XORPADgen/XORPADedit etc., and even repacking them back into their original format if necessary! Allowing users complete control over their game’s content without having to worry about potential compatibility issues between different platforms or regions! This makes ctrtool invaluable when it comes time for users wanting more out of their games than what’s available out-of-the-box!
Steps To Generate A Decrypted Rom From ctrtool
In order to generate a decrypted .nds/.ndi/.ncch rom from ctrtool, firstly users must ensure that they have obtained both an appropriate program (such as HackingToolkit3DS v15b) AND a copy of ctrtool installed on their device prior to beginning any work with their rom(s). After this has been done users should then select either Extract RomFS if they want just raw unedited data OR Extract All Files if they want everything including text edits etc.. After selecting whichever option suits their needs best users should then select which type of output format (.ndi/.nds/.ncch) they would like depending on their intended purpose before pressing (A) again allow ctrtool do its work! Once completed all extracted data should now appear within its own folder within whatever directory was specified prior starting extraction process!
Troubleshooting Steps If ctrtool Fails
If at any point during extraction process ctrtool fails due either invalid input/output paths or corrupt rom(s), then users should try double checking both their input paths AND output paths prior attempting another extraction attempt; ensuring that no invalid characters were accidentally omitted from path names OR that no typos were made when entering said paths into command line prompt window! Additionally some older roms may require specific versions/builds of HackingToolkit3DS such as v14b OR v15b instead newer versions due unforeseen compatibility issues; so make sure check this if all else fails too before attempting another extraction attempt using different versions OR builds HackingToolkit3DS instead default version provided by citra team itself!
Overview Of XORpad
XORpad is an important tool when it comes time for customizing roms which have been extracted via either ctrtool OR godmode 9 since it allows users easily modify various things such content restrictions & region locks present within those roms without needing access source code nor extensive knowledge programming languages themselves due its very simplistic yet powerful nature! Not only does XORpad facilitate easier modding but also much faster too since entire set modifications can be applied single click button rather than having manually edit hundreds lines code achieve same results when working without XORpad based tools like XORPADgen & XORPADedit etc.. !
Steps To Generate ROMS Ready For Citra
In order get rom(s) ready playing citra emulator after being modified using xorpads based tools like xorpadgen & xorpedit etc.. , users must firstly ensure that they have obtained both latest version citra emulator installed device prior beginning process customizing said roms second step involves actually editing said roms themselves via aforementioned tools xorpadgen & xorpedit allowing users perform wide range modifications such changing text strings content unlocks region unlocks unlocking special abilities characters etc.. ! Once finished editing respective xorpads pressing save button will apply changes made within program onto actual rom after which said modified rom now ready playing citra emulator thanks modifications performed earlier via aforementioned tools !
Troubleshooting Steps If XORpads Fails
