Hacking DSiWare Downgrade with almost ANY DSiWare Game!

[wiiu more like pee u]

QUOTED FROM PLAILECT:

"This has been released following Legends of Exidia getting pulled earlier today.

This works because one can paste over any DSiWare title's `.app` on the source system with a different DSiWare title's `.app` to replace it. It will launch just fine as long as the file size of the `.app` does not change.

The way FBI pastes over existing files performs in exactly the manner we want, overwriting the beginning of the file with our replacement data but not removing the old file, keeping the file size if the replacement is smaller.

Note that the savedata bin inside the `public.sav` file must be replaced, but not the entire `public.sav`file. For now this requires a PC.

In this case, it allows us to replace nearly any DSiWare title with SUDOKU v0 and sudokuhax."

It seems that the best titles for this are SUDOKU and Rytik Rock Edition, as they're both exploitable and only $1.99. They CANNOT be pirated and must still be bought from the eShop!

also they can't pull those games either since its not an exploit with the game and its a flaw with system transfer if you inject the old version of sudoku into a dsiware game with out modifying the size of the app and public sav files the game will be able to be transferred in system transfer

When you need to pull half of your games from the eShop to get rid of the exploit:

pretty much all of the good dsiware games are exploitable with this

Yeah threads like this just make ninty red flag it for the eshop equalling more people creating thread. If im honest, I would NOT be surprised if ninty had ninjas registered here for this purpose..

there not going to pull all the games because the flaw is in the 3ds not the game they will make a firmware update to patch it

I'm pretty sure that the flaw is the dsiware titles being able to read/write in nand since they get installed to the system memory and not the sd card .

yes so they have to patch it by making the old native firm not compatible with newer firmwares

It's now explained in the guide as I see, but I don't really get it yet. Maybe I'll need to read it twice.

 

[hacksn5s4]

well this was doable even before this guide came out all you had to do was find the old sudokuhax and the hax save file and on your already cfw 3ds overwrite the files with fbi of the new sudohax you got from the eshop

Will it work with dsi ware games bought on the dsi shop and transferred to the 3ds ?

It should

 

[hacksn5s4]

say if your source 3ds has a bunch of homebrew cias and homebrew dsiware can you just tranfer them to the target 3ds or will it not work or just not transfer the homebrew stuff and only the legit games you bought from the eshop

Only the legit purchased ones will be transferred, everything else will be ignored/wont be transferred to the target system.

so just reintall those once a9lh and cfw is on the system

Yup, correct.

People use to backup de nand so they can restore it after the transfer.

 

[Molina]

It will not work with every DSiWare, a minimum size is needed for .app and public.sav
Plailect is damn fast. updaded guide

There is a list of compatible DSiWare: list

 

[The Catboy]

I can't wait for Nintendo to pull every single DSiware game.
