I'm curious, similar to that of the download play hack being able to be done on 3DS etc, may this be the same, or not owo

Please explain for the layman - what are the implicaions of this hack?

Thanks.

Very little. This needs exactly firm 1.4.0 to work.
What are the odds you'll find a system with that low a firmware?

It's really not that hard to downgrade actually. You only need a DSiWare based entrypoint.

But if you already have a dsiware entrypoint, what's the point?
Userland on dsi is like arm9 hax on 3ds.

Actually no. Normal DSiWare hax doesn't have full access. You either have only slot-1 access via exploited Slot-1 games or nand/sd via DSiWare exploit but never both.

Arm7 is the security processor on DSi. It also handles audio.

Which we might get from @Robz8 or @shutterbug2000 or etc.
Who knows? This exploit + another dsiware (or system title) = death.

Buzzhax by NoCash...?
I wasn't directly envolved in making that, only indirectly at best (in terms of discussing some things).
Anyways, I think it will be greatest dsi-exploit ever.
And a funny one because it relies on a firmware feature that was intended to prevent homebrew code.

Indeed. Yeah I credited you because of the input you provided on it though perhaps the thread title should have included my name as well but this thread wasn't really made by me so I had no say in that.

Surely too the fact that you revealed a certain other oversight by Nintendo that I noticed, else I would not have dug where I did and found it. So that still counts for something. I seen over the years people get hyped up over a crash they found and go posting about it all over the place. Well I figured I'd go to some people that knows what they're doing first and get their opinion on it. Besides who better then the creator of No$GBA to debug this in No$GBA.

(besides if No$GBA wasn't a thing it would have been very difficult to attempt this or even know what's happening without a dev unit)

It will really end up being a group project most likely. Since I found the flaw I can name it. Certainly won't be BuzzHax. that's just the test stuff Gericom wrote for this.

Besides that most of my contribution to this was testing and working out how to get something going on hardware(and that's where the credit of Normmatt comes into play. I will try and remember to explain that when I post more info about this). It's great to see it work in NO$GBA. But the excitement doesn't start till it happens on hardware.

Does this occur early enough in the boot process to eliminate the need to use a hardmod for unbricking?

That really depends on the cause of the brick. But probably not.

Wait, did that 4swords game in the video have custom banner?
Is it related to the exploit, or you did it just for fun?

if this becomes a full blown exploit, maybe my DSi still has hope of being hacked!

Unlike 3DS, DSi top screen displays photos taken with the camera and doesn't use it for banners. "Banners"s are animated icons on DSi so those are on bottom screen. Nintendo didn't make "banners" separate from the icon until the 3DS. (and perhaps Wii. but that's a home console not a portable system)

So according to this, the console needs to be downgraded. You can either use an existing dsi downgrade method using a DSiWare based entrypoint or make and attach a hardmod and follow a downgrade guide.

If you do not have either of those things, then someone would have to discover/create/release/whatever a new entry point in either a system app or DSiware such as the Browser or Flipnote in order to downgrade if you do not have an existing way to run dsihax or have the ability to hardmod a DSi. No exploit to downgrade (or upgrade) a system to 1.4.0 is public yet.

Oh, I know about those animated icons, but I've never actually noticed that they're displayed only on bottom screen on a DSi.
I understand how dumb my question was. AFAIK, it's not even possible to alter that animated icon without breaking signature of SRL's header, so DSi wouldn't even boot it, right?
Well, at least it's possible to launch modified DSiWare's on CFW'd 3DS…

They need to discover an exploit? What the fuck?
