Hacking How to crypto-fix new DL roms

[lafleche]

Hi,

Can someone point me to a 'how-to crypto-fix' tutorial.

The latest DL roms seem to need it when running on Gateway

Are you trying to fix it yourself? You can only repack it (fixing it) assuming you have the game legitimately (have the SEED.DB) file.

@Ronhero

I'll give a small guide here.

Backup 9.0-9.2 nand.Update to 9.9 download game + update.Backup 9.9 nand and restore 9.0-9.2 nand.Make a fat16xorpad of your nand with Decrypt9 and pull your decrypted fat16.bin from the 9.9 nand backup.Mount fat16.bin in winimage and get your ticket.db and 00000000 that is the seeddb.Then use CDNto3DS to get the 3ds of the game and the cia of the update.Then use seedconv with the 00000000 file to get the seeddb.bin.

Then you would put the 3ds + seeddb.bin on sd card and decrypt with Decrypt9.It would use a combination of the 7x ncch + 9.6 seed keys to decrypt the romfs.But with this being a n3ds only game i don't know if it will use 7x ncch or 9.x ncch for decrypting the romfs.If it uses 7x ncch you will be able to decrypt it if it uses 9.x ncch you probably wont be able to decrypt it.

It will probably use the 7x ncch + 9.6 seed keys for the romfs crypto so you would be able to cryptofix it.

But it will definitely use 9.x ncch to launch the game so it wont run on the o3ds.

With the game using 9.6 seed crypto and probably needing 9.6+ fw it will probably use the new 9.6 ncch keys to launch the game.If thats the case the game would need 9.6+ emunand to work.

This was a post for Isaac, but should work just fine for everything else.

If i understand the whole thing right... GW's 100% rom compatiblity is gone. Every new DL title needs to be cryptofixed (by yourself or anybody who can) to make them working, correct?

Still has 100% compatibility, only if some games didn't work at all would compatibility drop.

This only affects the N3DS since its firmware can only go up to 9.5 on Emunand.
O3DS can go up to 10.0 without problems, so there'd be no reason to cryptofix the roms.

Well on my O3ds, gateway on latest emunand, there was no way i could get picross e6 working as 3ds rom
I had to install a cryptofixed cia.
So....no. Gateway is atm not 100% draganddrop compatible

Picross e6 is a game with 7.2 firmware requirement. That's really low. So I doubt it wouldn't work.
The most likely reason is that it appears to be a eShop game from what I could tell and so it might have been converted poorly to .3ds format

edit: I have no idea where you even found a rom of picross e6. I've been trying to find it for like 15 mins already and I get nothing. if you happened to find it in some kind of shady website, that could also be the reason it doesn't work.

edit2: finally found it. lol. Trying now.

edit3: I can confirm it freezes in the 3DS logo with an O3DS. But no idea if it's due to a poorly dumped rom like I said (since it's a eShop game originally) or if it's really due to crypto protection

It's due to the 9.6 seed encryption implemented on the new eshop games. To make the game works you need either to use the cryptofixed version or install the cia (non cryptofixed) first then visit the eshop page to get the seed.

exactly where it says gateway is drag and drop compatible on their webpage?

well.. it has nothing to do with drag and drop. GW is 100% drag and drop compatible since you can literally drag and drop any .3ds/.3dz rom to the mSD card of the red GW card and it will appear in the multirom menu.
Game compatibility is another thing altogether. And unfortunately, this isn't something that GW can fix I think. It will be up to whoever dumps the roms to fix whenever it's encrypted.

Correct. Some people still think it's a N3DS-only-problem. But that's just not right. My 2 O3DS's are refusing to launch newer DL titles because of the new encryption. So you have to hunt down the newest games cryptofixed or you won't ba able to play them.

The next problem is: Most new games come out as DL. The list of retail cart releases gets shorter and shorter.

Yea , what I meant is that it seems they just wanted to hit gateway sayiong that it wasnt 100 % compatible with "drag and drop" LOL
