Here is an amazing suite for coding DS Games, it looks very interesting but i havent had time to try it yet, and im hoping to start a community project going coding either a ds game, or some sort of app such as SSH, or network hacker sorta thing, there are already webbrowsers , linux emulators and remote control tools in development from this.
Well if it's Unix you're in luck. You can import tons of tools and utils such as C and coreutils which would be a goldmine for coding and exploitation.
