Homebrew [Rumor] Soundhax might be portable to DSi

[Rubberduckycooly]

ok i will se what i can do/find!

--------------------- MERGED ---------------------------

i have found the functions in the code!

now to find bugs!

 

[Thunder Hawk]

Yes, we must bring this dead system back to life!

 

[Rubberduckycooly]

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.

good point!
i will keep trying to find what i can!

edit: grammar

 

[Rubberduckycooly]

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!

 

[Rubberduckycooly]

bad news i have searched the code of the .app i downloaded from NUS multiple time with mutiple programs and ... nothing (of interest)

i would like to continue searching for bugs but to do what i will need some help from someone more knowledgable than i (or more info/files to search through)

Where's 33c3 when he's needed?

He is in my signature, making magic.

...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.

ok, that is good to know, i am starting to use a dissasembler now, but yes i did read some of the .app file in a hex editor
thanks for the info! hopefully now i can acctually look through the real code and find bugs

 

[ThisIsDaAccount]

@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!

 

[Rubberduckycooly]

what would the best way to dissasemble the .app files be?

because i dont have much experiance with dissasembling files

 

[Jayro]

So should I buy sudoku for my dsi xl now, or...

So should I buy sudoku for my dsi xl now, or...

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

 

[Jayro]

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.

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.
