Thanks, and what should I do after decrypting ROM ?No, you can
Just decrypt your Rom.3ds using CTR Decryptor by Roxas75 Tool
Riku's new tool Simple Cia v1.1 + rxtools can do this now without xorpads.
1. Decrypt ROM on your 3ds with rxtools.
2. ROM to cia with Simple Cia on your PC.
CIA will not be region patch or firmware spoof, what's the utility ?
