thechuckster has released a new version of Stella DS. It’s a port of the famous Atari 2600 emulator Stella to the Nintendo DS platform. Release notes:

I compiled in the latest version of chism’s FAT library. Now StellaDS should support more devices such as the Supercard SD. Tweaked the menu to allow wraparound. Began using Subversion to manage my source code under the suggestion of StoneCydh from #dsdev.
