ROM Hack [Release] 3DS_CTR_Decryptor-VOiD

[cracker]

well just a head up anyone having major issues getting a good xor dump, try another SD...i presume it must be down to the speed, but i have been trying to get a full dump of mario kart all day, and just tried with the U1 card i have in the gateway and the dumping is so much faster and got a full dump in one go

Do you think this is due to the FS ASM code used?

also there's still a lot of things to do for getting this as *releasable* state, just fyi. Tho it's decent this time.

Wow, testing out the new one and its moving so fast compared to the old one. Although, I did have to reboot my 3DS and try it a few times before it started working.

 

[Relys]

I just added xerpi's padxorer to the utilities!

If there aren't any issues I will pack all of this up for an official 1.1 release and include a better tutorial! (I'll give it about two days. I'm on vacation right now anyways) As always, enjoy!

Just finished and extracted. Amazing. 800MB pad(Mario & Luigi) in under 10 minutes!

Is there a way to view CTPK files yet?

This is as close as I got.

Being able to decrypt games now is amazing! I'm sooo excited to find unused content and junk~
Not to mention one step closer to game translations

all the ctrtools in the utilities are for x64
there's a build by Zecoxao of 3DSHax fork version compiled on 2014 08 28 working with x86 and python.

newer than 2 days ago?
the last commit to 3DSHax fork is from 2013.

he posted a link in this thread.

https://dl.dropboxusercontent.com/u/35197530/zip/ctrtool.zip compiled on cygwin, cluttered with all the dlls lol

Edit:
Maybe the change by namidairo (two days ago)?
or maybe the one from Plutoo is better?

Quick tutorial

Step 1.
Download these tools
https://www.sendspace.com/file/icnkiz
https://www.sendspace.com/file/4azlvg

Step 2.
on your pc drag the 3ds rom you want to decrypt onto ctrKeyGen.exe
this will generate
ncchinfo.bin

Step 3.
Copy Launcher.dat and ncchinfo.bin onto the 3ds internal sd card. (not the gateway micro sd card)

Step 4.
Launch the gateway exploit as you normally would by going into ds profile settings.

Step 5.
Wait while it generates a file on the 3ds
CTR-P-AKHP0.romfs.xorpad

step 6.
drag your 3ds rom onto getromfs.exe and it will create EncryptedRomFS.bin
copy CTR-P-AKHP0.romfs.xorpad to this directory also

Step 7.
hold shift in the folder containing these tools and the 3ds rom and right click and choose open command prompt here.
type in the command prompt
xor.exe CTR-P-AKHP0.romfs.xorpad EncryptedRomFS.bin
and it will generate
DecryptedRomFS.bin

Step 8.
Now run from the same command prompt
ctrtool.exe -x DecryptedRomFS.bin --romfsdir=My_Extraction_Folder

Step 9.
Profit ???

I'm getting stuff like that with ALBW image files. Strange image formats. probably weird tiling.

[andibad]

is awesome on v2, on 5 minute is already ~50 % (at 3DC00000) for pokemon X. but bit slow progress after 42B00000.

 

[Huntereb]

Probably been asked countless times, but any ideas as to when we'll see the ability to re-package roms?

I'm way too anxious for this... This is gonna be the reason I don't sell my 3DS.

Sorry, don't have my crystal ball handy, but i suspect probably not too much longer...that being said, there's still no good way to actually LOAD a decrypted Rom either..

 

[williamcesar2]

and another time you didn't even talked you did that...And again linking to 1000 tools Also you didn't fixed the thing, it's just faster thx to the other threads

man ! are you troll ?

 

[Huntereb]

Sorry, don't have my crystal ball handy, but i suspect probably not too much longer...that being said, there's still no good way to actually LOAD a decrypted Rom either..

Probably should have used different words, but I meant re-encrypt un-encrypted roms.

 

[SilverfalconLP]

im imagine can re-encrypt a un-encrypted roms whit zeros-key ,but i have r4 not gw....
