Ok, I want to make a CIA-backups of my Unchained Blades and NightSky.

I've already created xors, using rxTools. what to do next?

I need the CIA, from which I was able to extract romfs files

xor the xorpads against your .app files (should be 2 usually) then,

makerom -f cia -o output.cia -target t -i 00000000_decrypted.app:0:0 -i 00000001_decrypted.app:1:1

I am getting this when trying to create cia:
Code:
F:\cia 2>makerom -f cia -o output.cia -target t -i 00000000.app.out:0:0 -i 00000
001.app.out:1:1
[MAKEROM ERROR] Content 0 is corrupt

Open up the apps you think are decrypted in hex editor. if there is no 'NCCH' at 0x100, then you didn't decrypt it correctly.

You didn't show what was at 0x100 but I assume it's wrong anyway.

If you have an old 3ds I suggest using rxtools to decrypt. It skips the unnecessary xorpad stuff. Easier.
I can only generate xor using rxtool, when I select decrypt ctr titles - it displays "0 titles are decrypted" and nothing more. probably this only works with roms, not with apps.

Unchained blades? I had the game on PSP, and it was AWESOME!
yeah, if only there was way for repack it

if you want to extract the romfs, why do you want to create a cia?
just extract the contents from cdn (or your sd card).

your title says you want to make a cia, but your post says you want to extract romfs. they are different things :)
