Simple code for learning how RomFS level 3 works
Usage: Usage: lsrfs [romfs file] [path in romfs]
[romfs file] has to be decrypted. Use ctrtool and Decrypt9 to extract & decrypt the RomFS from any CIA / 3DS / NCCH.
[path in romfs] uses '/' as separators. If it leads to a directory, directory is listed, if it leads to a file, the file is dumped.
