Something looks wrong ith it.
I tried with the NCCH extracted from a DevMenu.cia and it generated 2 files named DevMenu (second overwrites the first one) and 1MB big, haha
The tool behaves awkwardly with stuff encrypted with zero keys, however they can simply be extracted without xorpads with ctrtool.
Yeah I thought there would be something like that. But I guessed it would simply be wrong xorpads, not entirely glitched results.
So, summarising, these are the steps to edit dumps of retail games:
1. Create a xorpad of the original 3DS ROM with the modified CTR_Keygen.
2. Decrypt the whole rom, then extract the contents of romfs.
3. Edit whatever you want in the folder that contains the extracted files of romfs.
4. Recompile a whole (temporary) ROM with makerom doing the proper modifications to a rsf file in order to rebuild the romfs folder.
5. Extract romfs of this new temporary ROM.
6. Replace the romfs of the decrypted ROM with the one extracted in step 5.
7. Rexor with original xorpad.
What about that rexoring part? What if the new romfs is bigger than the original?

With zero keys. Also, I don't think this works with cia files, you have to use the actual cci.
I think you could just edit your ncchinfo.bin to reflect the new RomFS size and generate a new xorpad.
Couldn't you then you xor it back after having the hashes fixed and reinsert the encrypted romfs.bin with makerom?
I don't get the purpose of this NCCH ctrkeygen for romfs modding.

The purpose is to get a single xorpad as I can understand, instead of one for every partition contained in the NCSD
The modded keygen still generates multiple xorpads, only it uses a NCCH container (CXI, CFA, or content extracted from NCSD) instead of a NCSD (CCI, CSU, 3DS rom).
Any hints for recompressing code.bin? Cheers
Rebuild the whole ncch: makerom.exe -f ncch -target d -rsf gw.rsf -o "%filename%.cxi" -exheader exh.bin -code code.bin -icon icon.bin -banner banner.bin -alignwr
it's in the 'Options' of the rsf fileAny hints for recompressing code.bin? Cheers
Code:
EnableCompress : true # Compresses exefs code
I don't even know how to load code.bin in a disassembler, let alone figure out the code... haha
OK, then according to you (because I haven't tried myself) the modified CTR_Keygen generates a single xorpad for a NCCH partition or is still divided in romfs, exefs and exheader; or both?
Still multiple xorpads. Only it was weird for that devmenu content, generated exefs and exheader as 'devmenu' and both were 1MB big. Probably the file used a diferent encryption.

@Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.+1 -
@
SylverReZ:
They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".

Nothing special about it other than it's more comfortable than the Lite+1

@SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme -

A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."+1 -

anyways, we need to re-normalize physical media+1
if i didn't want my games to be permanent, then i'd rent them -
@
BigOnYa:
Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.

@BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.
The issue is DRM -
@
cearp:
You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60

i like physical media because it actually feels like you own it. thats why i plan on burning music to cds
