Heres a great exploit for the Nintendo DSI:

  • This is an exploit for FlipNote that will allow running homebrew on your Nintendo DSi. Lovingly hand crafted by fincs and WinterMute, inspired by “ugoopwn” US region “leak” by Shutterbug.

    Simply copy the contents of the archive to the root of your SD card, open FlipNote and follow the steps in the video above. Make sure that you’ve switched off “Start on Calendar” or the exploit won’t work.

    The archive also contains dslink which can be used to transfer code over wifi but only with a WEP or open connection currently. DSiWareHax will install all the DSiWare savesploits for vulnerable DSiWare you have installed and fwTool will allow you to back up your NAND with included no$ footer for emulation.

    Please note: fwTool currently has no NAND restore options for the simple reason that it’s horrifically dangerous atm. I have some things in progress that will be safer but, for now, please don’t use any of the forks that add dubious NAND writing options. They can and will brick your console.
