# Petschko's RPG-Maker-MV File-Decrypter ## What's that? This Project is used to Decrypt (and Re-Encrypt) RPG-Maker-MV-Resource-Files that are encrypted with the Build-In-Encryption of the RPG-Maker. This Project is mostly used for Single-File decryption. >.< Please try out the [Java-Decrypter](https://github.com/Petschko/Java-RPG-Maker-MV-Decrypter) if you want decrypt huge amounts of Files (or more Projects) ### Motivation behind this As Art-Creator for the RPG-Maker by myself, it is sometimes hard to figure out, if somebody is using Resources from you (and may violate the licence like giving no credit or using a Non-Commercial-Resource in a Commercial Game for example). I don't have time to play through all the games so i just quick look at the files but its only possible if the files are not encrypted... Sad for me, more People use the build in Encryption from the RPG-Maker-MV so that's why I wrote this script - to get a quick look at the files without playing the whole game =) May some other artists will find this useful too. ### Legal-Notification You are **not allowed** to use the Decrypted Files (**if its not allowed by the origin File-Licence**). Please don't steal and reuse stuff that's not the idea of this Script! You can save them for Private-Use only. If the origin Licence allow use you can use them of course but please follow the licences! **If that's your Project** and you simply lost your Origin-Files, **you have the same rights**, to do stuff with them, **as before** =) ## Requirements - Web-Browser with HTML5 Support ## Installation This is very easy: - Download/Clone the Project OR direct use [it on my site](https://petschko.org/tools/mv_decrypter/) - Extract/Put it where ever you want - Done :) ## How to use? ### If you downloaded this Script on your Computer (Pre Step) - You have to open the "index.html" file with you Browser like: - Use right click and open with... _(Then select your Favorite Browser)_ - Use double click to open the file. Many Browsers set them as default applications for html files ### Use this Script now #### Decryption You want to see the Source-Files? Here you go: - Open the directory of the Game with the encrypted Audio/Images - Check if the Files have one of the File-Extensions: - ".rpgmvp" (PNG-Files) - ".rpgmvm" (m4a-Files) - ".rpgmvo" (ogg-Files) - If the Files doesn't have this Extensions the Creator used an other Encryption/Pack-Tool. If that's the case you can't use this script for this Project. - Get the Encryption-Key (This step isn't needed for Images) - Select with the first File-Picker the "System.json"-File which contains the "raw"-Encryption-Key - The File is located in `%PROJECT_DIRECTORY%/www/data/System(.json)` - Click on the Detect-Button - If it finds the Key, it will automatically insert it for you within the next Input-Field - Select the Encrypted Audio/Image-Files to decrypt - Click on the Decrypt-Button - **IF** you get an invalid Header Warning, turn off the Header Check. Just select "No" under `Verify Fake-Header?` and try again! - The Decrypted-File(s) are shown in a File-List, next to or below _(on tiny screens)_ the De/Encrypt-Button. You can open them and/or save them (or just view/listen) - Some Browser-Plugins like [UBlockOrigin](https://github.com/gorhill/uBlock) may block previewing the File. Disable it or explicit say `Open in new Tab` #### Encryption You want turn back an Image into the Game _(If you have translated text or fixed something on an Image)_? Here you go: - You need to check if you have one of these File-Types to turn back into the Game: - PNG-File (.png) - _Image-Format **make sure that's PNG** not JPG or something different_ - m4a-File (.m4a) - _Sound Format_ - ogg-File (.ogg) - _Sound and/or Video Format_ - If you have the Files in these Format you can go on, else turn them into the correct Format. (You should know how or [how to Google](http://www.giyf.com/)) - Like with decryption we need the Encryption-Key to encrypt your files correctly back for the Game - Select with the first File-Picker the "System.json"-File which contains the "raw"-Encryption-Key - The File is located in `%PROJECT_DIRECTORY%/www/data/System(.json)` - Click on the Detect-Button - If it finds the Key, it will automatically insert it for you within the next Input-Field - Make sure that `Verify Fake-Header?` is enabled (on YES). If not select it. - This checks if the Game can read this File - Select the File(s) you want Encrypt - Click on the (Re)-Encrypt-Button - **IF** you get an Error please check if you did all steps right before! Also check if the Header-Values are on default: - Click on `Header-Values (Show)` - Click on `Reset Header-Values to default` and click `OK` in the Confirmation box - Try again - The (Re)-Encrypted-File(s) are shown in a File-List, next to or below _(on tiny screens)_ the De/Encrypt-Button. You can't open them _(because its encrypted)_ but you should save them - Overwrite the File in your Game - Start the Game and check if the File is been displayed - **If the File is not displayed**: (This is very rare ~1/100 Games - Usually you get an Header-Error while you Decrypt Files from these Games them with the default Header-Values, that's an strong indicator that this Game has different Header-Values) - You have to set different Header-Values, for this you have to open this File: `%PROJECT_DIRECTORY%/www/js/rpg_core.js` - There you find the Decrypter-Class, its an insane long File so use the Search function (Strg/Ctrl + F) and search for this String: `function Decrypter()` - There are Values sort below, like this: ````js Decrypter.hasEncryptedImages = false; Decrypter.hasEncryptedAudio = false; Decrypter._requestImgFile = []; Decrypter._headerlength = 16; // <-- Header-Length (In Bytes) Decrypter._xhrOk = 400; Decrypter._encryptionKey = ""; Decrypter._ignoreList = [ "img/system/Window.png" ]; Decrypter.SIGNATURE = "5250474d56000000"; // <-- Header-Signature Decrypter.VER = "000301"; // <-- Header-Version Decrypter.REMAIN = "0000000000"; // <-- Header-Remain ```` Make sure that you copy the values (which have similar names to the fields in the Header-Info Form - I showed you them in my example above) - Try to encrypt the File(s) again ## Credits - [Petschko](https://github.com/Petschko) _(Me xD)_ - For creating this Project - [Stuk](https://github.com/Stuk) - For the ZIP-Library ([jszip @ Github](https://github.com/Stuk/jszip)) - [pieroxy](https://github.com/pieroxy) - For the LZ-String-Library ([lz-string @ Github](https://github.com/pieroxy/lz-string)) - [eligrey](https://github.com/eligrey) - For the FileSaver.js-Library ([FileSaver.js @ Github](https://github.com/eligrey/FileSaver.js)) - [Bootstrap](https://getbootstrap.com/docs/3.4/getting-started/) - For a bit more user-Friendly Interface - **Anonymous** - For the tip with the No-Key-"decryption" for PNGs *(This user want to remain anonymous, but this belongs to them)* ## Contact - E-Mail me if you have questions (no bug reporting please): [email protected] - Please report Bugs here on github.com use the "[Issue](https://github.com/Petschko/RPG-Maker-MV-Decrypter/issues)"-Section on this Project
