from BassAceGold:

Well after a short month, I finally got around to polishing this app off and releasing it Cheesy

Mario Paint Composer DS is an indirect remake of the music composer tool found in the Super Nintendo game “Mario Paint” with a few new adaptations which I added in from the PC version created by unFun Games (http://www.unfungames.com/). Please note, I am not responsible for the pc version, these two programs merely share the same name and that is all. This is not a direct port of any version, it is completely coded by myself.

Features: These are new features continuing from the ones already in the snes version

-Saving and Loading of songs
-Sharp and Flat notes
-more lower ranged notes
-4 new note types
-4 notes per can be played at once rather then the 3 limit
-Longer songs

Feel free to check out the forums for songs to download, to share your own creations, report bugs or even to drop a suggestion you would like to see in the next version.
