[Huntereb]

We've been getting a lot of nice stuff on the 3DS scene lately. It's like a super long Christmas. I wonder when our next surprise will appear...

Just a question, do you plan adding the instructions or the nfo back to the OP for peeps new to the thread? i only ask because i've come back to this thread after some time, and forgotten the instructions

Yes its compressed and encrypted. My packer apparently isn't working I'll have to spend a little time working out why at some point, once it is, I'll release it.

Did you looked the exeFS ? i am really curious if it work with JIT, i don't have much time this week to it, because, if it is possible on 3DS, we can write really very GOOD emulators to 3DS(it's PSX, CPS1, CPS2, Neo-Geo).

why not just make the slot0x25KeyX readable from slot0x25KeyX.bin just like ncchinfo.bin?

Quick question.
I have the value, so do I just key the hex into notepad and save as .bin?

You will need to edit in HEX mode or else you will be saving ANSI characters->HEX which will be different.

Use HxD, bvi, or a plugin for Notepad++ (which is what I use).

no, use hex editor.

Thanks Relys and st4rk for your prompt replies.

I'm presently trying to create a .cia from a card2 game,
to see if I can use the .cia save game transfer from card2 onto .cia

I'm using Pokemon X as an example,
and I already have slot0x25KeyX.bin on my sd root.

Step 1. Drag game onto ctrkeygen for ncchinfo.bin
Step 2. Copy ncchinfo.bin into sd root
Step 3. Run launcher

At this point, I run into an error:

Opened! Reading info...
Number of entries: 6096128
Too many/few entries, or wrong version ncchinfo.bin

Any idea what I'm doing wrong.

-Pushed quick fix for memory leak in ncch_info_createepad

 

[Queno138]

The error persists on my end.

Could it be because I am not using your ctrkeygen?
I'm not good with pythons

(I'm using the common ctrkeygen.exe that I could find)

Or maybe I didn't hex edit properly?
(heck, I used hxd and just copy pasted the hex into the hex areas)

Reading the python script I think they volontarily add FFFFFF at the start of the file so old tools stop working cf :

#4 bytes = 0xFFFFFFFF Meant to prevent previous versions of padgen from using these new files

You just have to install python 2.7 to make the python one working, then drag & drop the rom on it works like the exe one.

Nice one! thanks Relys!

Now that we have access to the NCCH partitions stored on the SD card, when can we get a tool to add NCCH partitions to a NCSD so that we can make usable CIA backups?

 

[kaidex]

there should be some tools can unpack romfs to folder and vice vesa. I found a old post Romfs generator, is it works on your folder?

yes,i used crtools to extract romsf.bin on the folder.What should i do next?
