You can see Yasu leaving the photo gallery.

Explain please?

It's similar to the PSP generation in downgrading again

Using a buffer-overflow in the format

I'm interested in seeing where this goes.

Let's hope it is =D
Good work Yasu

Wouldnt it realy be totaly dumb for nintendo to make the same mistake like SONY ... ? I mean it works on PSP and PS3 ... they maybe should read news about consoles =/

Explain please?

A purposely malformed image file causing a buffer overflow, allowing code to be run.

The TIFF file format is unusual in comparison to other image formats, in that it is composed of small descriptor blocks containing offsets into the file which point to the actual pixel image data (composed of bands of pixel rows). This means that incorrect offset values can cause programs to attempt to read erroneous portions of the file or attempt to read past the physical end of file. Like most other image file formats, improperly encoded packet or line lengths within the file can cause poorly written rendering programs to overflow their internal buffers. Properly-written image rendering programs generally avoid such pitfalls.

Multiple buffer overflows have been found in Libtiff. Some of these have also been used to execute unsigned code on the PlayStation Portable, as well as run third party applications on the iPhone and iPod Touch.

Awesome! So soon already!

It would be totally awesome to have some kind of YSMenu-like firmware in the DSi

Probably won't happen, but even running simple homebrew would be totally awesome!

What - The PS3 has been hacked?
I've had one sitting around for a few months doing nothing
Are you sure?

Just google about for "TIFF PS3" , AFAIK its nothing stable, just the first attempt to run unsigned code

** And now back to the DSi =/ **

Hmm... so if its designed to run from TIFF by the integrated browser, it is needed to get access to both processors, and if thats done it shouldnt take that much, since the DSi is like DS in the code-part

I'm doubling the wager that it was infact a buffer overflow exploit

It could definitely lead to unlocking the firmware and developing our own custom ones... that would be pretty rad

It was time I think...

Knowing Nintendo's sh*tty firmware systems, who the hell would want to develop a custom firmware for the DSi in the first place?

This is a translation of a translation.
A Korean guy in the korean rom hacking forums translated the japanese into korean, and I'm translating the korean into english that you guys can understand

Original
DSi?HelloWorld????????????????????????????
?????????????????????????????????????
???????????????????????????????????…
CFW?????????FW????????????jk?PSP??????????

Korean
(??) DSi?? HelloWorld ??? ??. ???? ???? '?' ????. ??? ?? ?? ??? ?? ???, ??? ? ??? ?????. ??? ???? ??? ?????, ??(????) ??? ????.. ??? ???? ?????. ??? ????... CFW(??? ???) ????? ????, ???(FW)? ??? ???? ????..? PSP? ??? ???.

English
(Translated) Making HelloWorld show up on the DSi successful. It was done by "the" way that you guys were thinking. The one who ran it was a person with a DSi, not me. However, I will wait a little more until I release what I found out, because I don't support the common use of flashcarts.. First of all, I need to get the actual device. Will they still sell it... CFW(Custom firmware) would be nice, but wouldn't there be a signature on the FW(firmware)? [note from psycoblaster: by signature, read mystikekoez's post right below this.] How was the PSP done?

MystikEkoez · Nov 4, 2008

Firmwares are "signed" by the developers so that they will install.

Raven Darkheart · Nov 4, 2008

wow nice work on the hack
now correct me if im wrong but..if this is indeed the buffer overload hack
it should be a firmware hack right?

nobody is sure. But the korean translator translated a part like this:
???? ???? '?' ????

???? = everbody, also another way to say "you guys"
???? = think/ what you thought
? = the/that etc
???? = with the method

The sentence as a whole says how he used "the" method that we were thinking of. How vague.

MystikEkoez · Nov 4, 2008

Well, the way that the PSP did it back in the day was use the TIFF exploit to modify the firmware on the PSP to run unsigned code. After the IPL's were discovered, they moved on to create custom firmwares as the later official firmwares no longer had the ability to be exploited, plus the newer official firmwares had desirable features. So, they (DAX/Dark Alex) proceeded to modify the firmware itself and basically "pre-hack" it. Of course, to install these pre-hacked firmwares that are basically unsigned, you would have to use an exploit such as the TIFF exploit or now in this modern age, Pandora, in order to actually get the CFW on your PSP. I remember the good ol' days, where you would have to use a GTA disk to downgrade your PSP then install CFW... Yeah..

But yeah, before any discussion of CFW is even made, a reliable firmware hack needs to be produced.

And just what did I say?

Vulpes Abnocto said:
Our people don't have the resources to throw into this problem that Ninty does, of course, so you won't get your solution tomorrow, nor the next day, and most likely not even the day after that.
But before long you'll see a topic around here saying something to the effect of:
"DSi working with homebrew - here's how!"

Speculation: $0
Anticipation: $0
Irritating whining about whether the DSi can ever be hacked: $0

Being exactly right on the timeline of how and when the DSi will be hacked:
Priceless.

\o/ Way to go Yasu! Keep it up my friend!

Looks promising, I believe its some alternate firware, i doubt that flashcards will be able to work on this thing yet.

Homebrew and commercial roms, without carts is a great feature for the dsi. I might think of buying one.

Btw, do you guys remember when Team 17 said that they were afraid of DSi's SD-slot? Haha, they were right.

BakuFunn · Nov 4, 2008

oh wow, hacked already.
Another lightning fast solution by Yasu
He truly is the pirate god.

Also, since it is using the TIFF hack, it could be a long time before people find a way to acually make a CFW.
I mean like, look at the psp. the TIFF hack was very temporary.

Hacking Nintendo DSi hacked!
