Hacking [Tutorial] How to Decrypt 3DS Roms for Dummies

[Kandern97]

Restart your 3DS and try again until it works. The older version is bad with handling threads...

I've done that like 5 times already. Do I need to do reboot and retry even more? And how long should I wait before rebooting?

Yes.

And how long should I wait before rebooting?

It should immediately start creating the xorpads.

 

[Kandern97]

Yes.

It should immediately start creating the xorpads.

Ok, thanks, I'll try that. Also, does trimming affect it at all?

Nah.

Ok, so I'm at step 3. And I'm getting stuck at "Opening sd:/ncchinfo.bin ..." it won't move forward. I'm trying to decrypt Cave Story 3D, and I've tried it trimmed and untrimmed (the rom) and neither of themseem to work. help?

Use the untrimmed one, but dump the ncch again. For whatever reason mine took 4 times before it started working.

OK, does the act of trimming and then untrimming affect the rom in any way in relation to making the xorpads?

Nah.

Ok, thanks. After 10 ish times of trying, it's started to work! It shows the .exh.xorpad, the .exefs.xorpad, and the .romfs.xorpad. Should there be something else to wait for like the banner or something? (BTW I'm a noob if you couldn't already tell)

7. - Run the batch file 1-decrypt.bat (just double click)

8. - Run the batch file 2-extract-romfs.bat (just double click)

stuck at step 7 & 8 the .bats open & close instantly could this be because i'm using win 8.1 64bit ?

I'm on Win 8.1 64-bit and it works fine for me. Make sure that your Romfs.bin and romfs.xorpad are in the workdir folder, and then re-run. If that doesn't work, run as admin.

nvm

np, there is no real reason for it to be complicated, a pretty simple 4 step process with a properly made batch file ......i could probably make the bat file simpler if i knew the end user would only have the one .3ds file in the folder

it seems to have worked this time but i'm not sure how to install it in my 3ds as i all i have is bin files no CIA !!

i managed to create the cia file but sadly i got NCCH & CIA warning errors so i think i will give it up for now & wait until someone makes a tutorial for converting .3ds to .cia

That one is okay!

It's just telling you it won't be encrypted or something.
That's pretty much the last step

Go install the .cia!

Look at the image for better understanding!

It's been on the "Reading info..." screen on the 3ds for some minutes. Is it normal?

Yes it's "normal", reboot your 3ds until it works.

 

[Mylink5]

Ah, so it's supposed to be over quickly ? Ok, thanks! Also, thanks for the 3DS to CIA guide, I'll be trying it later!

It's only normal on the old version that's packed in with this tutorial. I've had zero freezes with the latest version.

 

[Mylink5]

Where can I find the latest one?

Just incase someone here doesn't have a 4.5 3ds... Will this be deleted by a mod?- Probably,
Will i get another warning level?- Probably, Do i care?- meh. Requests in ''Youtube Comments''

[dbzkamehameha]
