https://gitlab.com/Petschko/Java-RPG-Maker-MV-Decrypter

This Project is used to decrypt RPG-Maker-MV/MZ-Resource-Files that are encrypted with the Build-In-Encryption of the RPG-Maker.

This Project is also able to decrypt whole RPG-Directories. It's similar to my previous Project but more comfortable.

You can decrypt the Build-In-Encrypted Files from the RPG Maker MV or MZ. They usually have the extension .rpgmvp, .rpgmvm, .rpgmvo, .png_, .m4a_ or .ogg_.

Just double-click on the JAR then the Program should start (If not try the BAT-File - Windows only)

Click on the Menu "File" then "Open"

Wait for a short moment =)

If there are Files listed and a Decryption-Key is in the Text-Box you're ready to Decrypt

(Not yet implemented) You can also Decrypt single/multiple Files - Select them in the Project-Files Tab after that you go to "Decrypter" -> "Selected Files"

You can also Re-Encrypt Files (For example if you translated text on images for the Game)

You can also check out the "Option"-Menu and check if the settings fit to you =)

(Not yet implemented) You can find this "Manual" also within the "Info"-Menu

In some case it can be useful to do stuff via the commandline. For example, you want to mod a game and make it easy for the user to mod it (like they just need to start a .bat/.sh file which does the stuff)

For details use and examples how to use it see CMD Instructions

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 (even if I want^^). So I just quick look at the files, but it's 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 Program - To get a quick look at the Files without playing the whole Game =) May some other Artists will find this useful too.

It can be also useful for Translators, e.g. when you want to make a Game available for different Regions. (IMO you should ask the Creator of the Game first! - Sometimes it's not possible...)

I'm also interested in Encryption in general, so this was a good base to learn, since the MV-Encryption is very weak - But it's great that's simple, because it will not slow down weak machines! (See below)

Sometimes there is a nice Picture that you may save for yourself. You would even do with without this Decrypter by making a Screenshot (or record the Sound) >.
