This free utility will convert a
- Megatouch .SPR or .SPR.GZ file to .PNG
- .PNG (or zipped PNG, for animations) to .SPR.GZ
You can use this utility to replace game images and animations. If you want to create an animated sprite, zip each frame of your animation with filenames: sprite000.png, sprite001.png, etc.
Transparent sprites and PNG files are supported.
