+`3dsconv.py` is a Python script that "converts" a Nintendo 3DS rom (.3ds, .cci) to an installable CIA (CTR Importable Archive).
 
 It supports using only an ExHeader XORpad, as well as decrypted roms. The ExHeader XORpad name format is `<TITLEID>.Main.exheader.xorpad`.

 This does not work with Python 3.x.
 
 ## Generating XORpads
-If your rom is encrypted, you must generate ExHeader XORpads with a 3DS system and the ability to use Decrypt9. Use `--gen-ncchinfo` with the roms you want to generate them for. Place `ncchinfo.bin` at the root or `/Decrypt9` on your 3DS SD card, run Decrypt9, and go to "XORpad Generator Options" and "NCCH Padgen". XORpads can then be placed anywhere (use `--xorpads=<dir>` if it's not the current working directory)
