https://gitlab.com/Petschko/RPG-Maker-MV-Decrypter
This Project is used to Decrypt (and Re-Encrypt) RPG-Maker-MV-Resource-Files (MZ-Files as well) and that are encrypted with the Build-In-Encryption of the RPG-Maker.
This Project is mostly used for Single-File decryption (But it is able to handle multiple files). >.< Please try out the Java-Decrypter if you want decrypt huge amounts of Files (or more Projects)
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.
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 =)
- Web-Browser with HTML5 Support
This is very easy:
- Download/Clone the Project OR direct use it on my site
- Extract/Put it where ever you want
- Done :)
- 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
You can restore all image files without having the decryption Key. If you want to get the Audio, you need to do the decryption
- Go to the Tab Restore-Images (No-Key)
- Select any encrypted PNG-Image-File(s) (Extensions:
.rpgmvpor.png_) - Click the Button Restore Original Files
- Download or view the Files on the right side. You can open them and/or save them (or just view/listen)
You want to decrypt Audio or image Files? That is how it works:
- Check if the Files have one of the File-Extensions:
.rpgmvp,.png_(PNG-Files).rpgmvm,.m4a_(m4a-Files).rpgmvo,.ogg_(ogg-Files)
- Get the Encryption-Key (This step isn't needed for Images - Look at
Image "Decryption" without the Key)- Select with the first File-Picker the "System.json"-File OR any .rpgmvp/.png_ File from that Project
- The File is located in
%PROJECT_DIRECTORY%/www/data/System(.json)for RPG-Maker MV - The File is located in
%PROJECT_DIRECTORY%/data/System(.json)for RPG-Maker MZ - You can also use an Encrypted Image-File from the Project (
.rpgmvp/.png_) to detect the Key
- The File is located in
- Click on the Detect-Button - If it finds the Key, it will automatically insert it for you within the next Input-Field
- You can also manually put the encryption-Key in the Text-Field if you know it.
- Select with the first File-Picker the "System.json"-File OR any .rpgmvp/.png_ File from that Project
- Select the Encrypted Audio/Image-Files to decrypt (You can select multiple here)
- 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!
- IF you get an invalid Header Warning, turn off the Header Check. Just select "No" under
- The Decrypted-File(s) are shown in a File-List. You can open them and/or save them (or just view/listen)
- Some Browser-Plugins like UBlockOrigin may block previewing the File. Disable it or explicit say
Open in new Tab
- Some Browser-Plugins like UBlockOrigin may block previewing the File. Disable it or explicit say
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
- PNG-File (
- 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)
- Get the Encryption-Key (This step isn't needed for Images - Look at
Image "Decryption" without the Key)- Select with the first File-Picker the "System.json"-File OR any .rpgmvp/.png_ File from that Project
- The File is located in
%PROJECT_DIRECTORY%/www/data/System(.json)for RPG-Maker MV - The File is located in
%PROJECT_DIRECTORY%/data/System(.json)for RPG-Maker MZ - You can also use an Encrypted Image-File from the Project (
.rpgmvp/.png_) to detect the Key
- The File is located in
- Click on the Detect-Button - If it finds the Key, it will automatically insert it for you within the next Input-Field
- You can also manually put the encryption-Key in the Text-Field if you know it.
- Select with the first File-Picker the "System.json"-File OR any .rpgmvp/.png_ File from that Project
- 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 (Of the RPG-Maker which is used)
- 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 defaultand clickOKin the Confirmation box - Try again
- Click on
- IF you get an Error please check if you did all steps right before! Also check if the Header-Values are on default:
- 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 (Maybe make a backup of the game before doing that)
- Start the Game and check if the File has been displayed
- If the File is not displayed: (This is very rare ~1/100 Games - Usually you get a Header-Error while you Decrypt Files from these Games them with the default Header-Values. That's a 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- For RPG-Maker-MZ the File is here:
%PROJECT_DIRECTORY%/js/rpg_core.js
- For RPG-Maker-MZ the File is here:
- 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:
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)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
- Try to encrypt the File(s) again
- You have to set different Header-Values, for this you have to open this File:
- If the File is not displayed: (This is very rare ~1/100 Games - Usually you get a Header-Error while you Decrypt Files from these Games them with the default Header-Values. That's a strong indicator that this Game has different Header-Values)
