May have found a good exploit with DSi Sound. I have been messing around with m4a files and have almost achieved what I wanted. This exploit will be better and easier than the Drunken-Coders' DSi-Mode save exploit. There will be no space limit. When it is done you will be able to run unsignedcode using a m4a file in the DSi Sound channel/app. The2Banned2One 21:56, 19 August 2010 (UTC)
