ROM Hack [Release] 3DS_CTR_Decryptor-VOiD

[dubbz82]

And to use ctrtool, put the decrypted romfs in the folder with it, then use this syntax:

ctrtool DecryptedRomFS.bin -t romfs --romfsdir=PATH YOU WANT THE FILES EXTRACTED TO

Thanks, this helped me immensely actually, in combination with your tools.

Someone can make a step by step guide to extract Audio Files from a rom, and can play them easily.

Would really appreciate it

Well it goes kinda like this:

1. Get the keys from the ROM (ctrkeygen)
2. Put the resulting file in the SD. Then launch padgen on 3DS
3. Wait. Might take an hour or so.
4. Use the generated OTP/XORPad to xor with the ROM. The pad must be the same size as the ROM, if not, cut it.
5. Use ctrtool to extract content from the romfs. All game data, including models, graphics and sound should be in there.

Additionally vgmstream + fb2k can play bcstm files.

Well, i guess it won't be long before some scene rom dumper decides its a good idea to decrypt, include scene splash screen, re-encrypt and then finally release the rom

Any known cases of that. I don't care if they do this because I'll be dumping my own roms soon.

To what end? Clean dumps are already out there for most everything, and there's no special protections on anything.

Same reason as anything. "BBB dumped this game. We are the 1st". This is what happens rather frequently. They get recognition, more people use their dumps. They make more dumps.

also anyone with a 4.x 3DS and Gateway can dump a rom

The fact that there's an object named "Poohole" in Super Mario 3D Land just makes me want to be able to view the models MORE.

maybe makerom has a bug, the section .code is very small

if we fix that bug could we have this decrypted files back into a .3ds?

Has someone been "trimming" roms from all the junk, like updates for instance?

 

[WannyTiggah]

I read all this thread and I'm crying buckets for having my 3DS with 8.1.0-19U. I want to extract the hell out of Pokemon X and NSMB2

My only consolation is that my DSTwo still works with it.

no

So in order to temporarily alleviate the hour-freeze, I have compiled a series of launchers that start decrypting at a specific MB. The Launchers range from 200MB to 2000MB. If your XORpad freezes at 734MB for example, choose the 700MB launcher and merge the the xorpads appropriately

For some odd reason, the 500MB launcher.dat decided to just skip over the 3rd pad (romfs), leaving it incomplete, and go to the 4th and complete that one (I think it's a system update file), then finish. Not sure why though.

THANK YOU THANK YOU THANK YOU!!
So you extracted ExeFS? Why not the RomFS because that's where the data is.

I also extracted the RomFS.

I also extracted the RomFS.

Can you please post some pictures of the files.

 

[SciresM]

Can you please post some pictures of the files.

Most .szs files have the szs modifier icon on my pc, but note that the program can't actually open them:
