Hacking 3ds sd card hack theory

[Quget]

I tought i check out the sd card since you are able to download gba / gbc / gb games on your 3ds.
Most logic thing is that it will be saved on your sd card.
I went to : H:\Nintendo 3DS\dbd1e8c1294970ff6202ec1a16269075\533600b24760aab0534430320002544d\title\00040000\0004ab00well checking out the folder data i saw a .sav file.
This must be a gba game I have on my 3ds. (The free zelda game)
The directory is like.

H:\Nintendo 3DS\Some huge id?(or random\Encrypted)\Title\00040000(guess this is always like this)\0004ab00(Name encrypted? or game id? Idk).
So my guess is that it is possible to convert a gba game to something like this. Did anyone already found out more information?

It would be nice if someone could try putting this on their sd card and check out if the game would work ?

I'll do it

The free zelda game is a DSiWare title = DSiWare Game probably not possible

I put it on my SD card just to check, but am I supposed to put in in the root folder? Because when I do that, I don't see anything new in my 3DS.

The .sav files are encrypted and only works with your specific 3DS.
Unless we get the keys it won't work for anyone other than you.

 

[frogboy]

Nope.

the keys may be in this file. phtcache.bin

Dsiware and 3dsware savs probably are the same format as 3ds retail game saves.

I haven't checked but I'm quite sure they are also XORed and the key is in the sav itself.

People swapping around the files on their SD card is extremely obvious, of course they're encrypted and/or tied to information stored in your 3DS itself (meaning not everything is on the SD, there's some critical parts in the 3DS's storage).

with the same way is there any chance anyone to share metroid fusion??is it gonna work?

if its a DSiware it wont be on th sd card it be installed to the internal ram of then 3ds

You can't swap files, they are linked to the console.
Save files don't have the key inside (the key is in the console).
Sharing games here is 1. not allowed, 2. not useful as they are encrypted.

If you want to talk about hacking idea by swapping files on SD card, you can continue in the main hacking theory thread.
