DuSTED is a DS homebrew application I wrote. It is a tile editor for GBA and DS hardware-based graphics tiles that actually runs on the DS. It works, but its in a very rough state and I haven't worked on it in awhile, but I decided to release it in the hope that someone might find it interesting and/or useful. It is licensed under the terms of the GPLv3.

devkitARM is required to build it, and homebrew capable DS hardware (or an emulator) is required to run the resulting executable. I have not tried it with any DS emulators.

The source can be downloaded here.
