ROM Hack [Release] 3DS_CTR_Decryptor-VOiD

[_eyCaRambA_]

So, two questions again, sorry.

1) So I thought about creating eShop 3DS ROMs from games you own directly from the CDN. Is this possible? The ticket.db only includes system application stuff as far as I can see.
2) With the tons of public, recent progress - do we have a possibility to decrypt savedata yet apart from the limited use of savedatafiler? I mean, we can decrypt NAND, ROMs and SD content but I haven't seen any recent approach on savedata yet.

It is. You must have decrypted your 4.x NAND, while you have to dump and decrypt your emuNAND to get the most recent tickets.

Ah, I actually decrypted an older emuNAND dump I had -- guess I haven't downloaded anything from the eShop back then. Thanks for the clarification, much appreciated

NAND decrypted succsefull! Thaaaaaaaaaaaaaaaaaaank you! I wanted to done this since a looooooooooooong fuckin ago
I tweaked a little your script for extract each NCCH I find a lot of "XXXXbuilder", "CTR-N-HXXX" and "CTR-P-CTAP" titleids. I found one with 6_3_0, now I'll try decrypt it and see what is~
-----------------
Edit: Garbage, there was two files "Version.bin" and "cup_list". The content of Version.bin is:
00 03 06 00 45 00 00 00
Seems preatty simply to understand, and idk what is cup_list D

I'd be interested to see if the Japanese & Korean keyboard components could be dumped and installed on a US 3DS.

So it was hiding on my NAND the whole time, eh

 

[Lord M]

ehm and in theory what will be possible with all these decryptions in work? XD

I want to believe we'll be able to install games that will work on SysNAND too.

It's easier to just go into the "title" folder in the nand and see them that way

You can't see the ones that were deleted that way. ;p The script recovers them.

I made this bat file in case someone is having issues extracting the FAT16 partition.
It uses the 'tail' utility to extract the relevant part of the nand dump.

Just drag your nand dump onto the bat file.

 

[bobmcjr]

How do you mount/access the contents of the FAT16 partition? I applied the xorpad, but I didn't see anything that looked like partition info. Although there is some plaintext in it now.

 

[Vappy]

I used the advice of einstein95 and got a copy of WiniMage, was able to read and extract it fine.

Is decrypting of digital games possible? Like Pushmo, Photos with Mario or AR Games. Or is this limited to cartridge-based games?

Digital games are exactly the same as cartridge ones, the only difference is a flag set on the exheader saying they can run from the SD card.

 

[drwhojan]

Compiled all latest tools , Figured out how to and tested

For them who don't, well here attached .

 

[piratesephiroth]

but doesn't relys share them already compiled?

how/where did you find this address 0x0805CF05 (from fileOpen function in FS.S) ? Thanks.

I guess it is just a matter of dumping the 3DSWare (which I assume can only be done by some groups).

All that's necessary is that you (or someone with a Gateway) have purchased the game.
Then you can either decrypt the installed game on your SD card or you can decrypt your NAND, get the decrypted title key for that game, download the contents straight from nintendo's servers and decrypt them with the title key.
