Using Tinke
Tinke is a program to view, convert, and edit the files of NDS games. You can edit a lot of file formats, like images, text, sounds, fonts and textures. Furthermore, it works with plugins made in .NET Framework languages (C# and VB.NET), so it's so easy to support new formats.
Tinke was discontinued by it's original author, pleonex, and its being continued by TBNSMB. (tinke-ultimate)
So in this guide i'll be using tinke-ultimate.
You can find the latest version of tinke-ultimate on it's repository
When you open the executable, it will ask for you dumped game.
Once you open it, it will look something like this.
- In Sonic Rush: Most of the sprites seem to be on the act folder.
- In Sonic Colors: They seem to be compressed in various folders and .narc
- In Sonic Rush Adv: Not tested.
You can preview a bac file directly on tinke, but only the first frame, and the size is not defined.
To do so, you must click on the bac file and click on View on the sidebar;
Input multiples of two for the width in the preview window until the image appears right. (e.g: 8, 16, 32, 64, 128, etc).
Once you found a bac file that you want to extract, just click on Extract and save it somewhere as a .bac file.
