TMNT Tello

The sprites in TMNT Shredder's Revenge are stored in compressed XNB files called ZXNB. This tool allows you to extract them into PNG files.

Extracting PNG image files

• To get started, if you haven't set your game folder yet, click on the Game Folder button and browse to the Content folder of your game installation. For example, if your game is installed in C:\Program Files (x86)\Steam\steamapps\common\TMNT\, browse here and select the Content folder.
• In the Folder Browser area, you will see a list of folders which have ZXNB files in them. (2d, Editor, Fonts, etc.)
• Click on any folder to see all the ZXNB files in it and all its subfolders.
• Expand it and click on any of the deeper folders to narrow down the listed files.
• Click on an item in the ZXNB files in folder area to load that image in the Preview area.
• To export images, you can right-click on the Preview area, click "Export as", and browse to where you want to save the file. You can also use the Export button. This requires that you enable the Same folder setting or select an output folder using the Output Folder button. A drag-and-drop functionality is on the to-do list.

Using the modded PNG images in the game

• Put the modded PNG image in the same folder where its original ZXNB file is.
• Make sure that your PNG image file has the same name as your original ZXNB file. For example, if you had Leonardo.zxnb, rename this into Leonardo.png.
• Back up your original ZXNB file (e.g. Leonardo.zxnb) by renaming it into something else (e.g. Leonardo - Copy.znxb) so that the game doesn't see this original file anymore. The game will ignore the PNG if a valid ZXNB file is found.

Compressing the PNG images back into ZXNB files

• This is an optional step and is not required for you to see your modded in the game. This function is a work-in-progress.

FALSE POSITIVE warning

For some reason, this app may be trigger a false positive in anti-virus software. I can confidently say that, as long as you got the file(s) directly here, that there's no way that's true. All the source code is available so you can check this.
