    ok some good news and some bad news!
    the good news is i have read a lot of the code and understand it a lot more!
    the bad news is i may need a nand dump or the dsi SDK to go further since the .app file CONSTANTLY references external (.c) files (that or i need a more decrypted .app since there are lots of random symbols in the file)

    EDIT: it also looks like either i need to decrypt the .app file more or get thise .c files because from what i can see the file doesnt acctually DO anything interesting BUT i think i have found "if" commands in the encrypted stuff (not all of it is encrypted, most is though)

    It could also be compression, rather than encryption. So unless you haven't already decrypted the .app, it could just be a type of compression.

    is it common knowledge that the dsi can play .mp4 files? (only the sound of course :))

    EDIT: source; i put the switch trailer .mp4 on there and it played!

    ...and you've done all this by "reading" the encrypted application file in a hex editor?

    EDIT: Even if it is a decrypted version (can't tell from this post; there's no "more decrypted" version, just encrypted or decrypted), I'm not sure where you're getting this idea that the file references "external (.c) files". DSi applications are completely self-contained, compared to 3DS applications that can use system modules.

    @Rubberduckycooly Thanks for taking the time to do this! If you ever need testers or help (can't really do much but grunt work, but happy to do it) feel free to ask me!

    if you have the funds, go for it! i am not saying i am going to find an exploit, i am just saying i would like to browse the code to see if one exists (and then maybe make an exploit)

    it will be a good backup, if you find a way to inject the exploitable version of sudoku into sudoku

    If decryption is the only thing standing in the way of DSi-mode exploitation, then hopefully someone makes DSi hacking progress. I'd personally love to see a flooded flashcard market again for DSi-mode NDS cards.

    i dont think decryption is a problem, i just need to learn how to dissasemble the .app files and browse the code

    Well I wish you the best of luck, I really hope you find something. You could be hailed as a DSi scene hero. :yaynds:

    We are all waiting for that! The DSi is the only console which hasn't been fully-hacked with his own mode. I can't understand how a newer console can have thousands of exploits and this console only have a exploit which is not in the system and you must pay for it.

    Well to be fair, the DSi is just a DS revisioning, so they patched many DS exploits. But the 3DS is a fresh new complex system with many entry points.
