Functions

func Download

func Download(titleID uint64, version uint16, downloadTicket bool) (*wadlib.WAD, error)

Download downloads the specified title. Requires both the high and low title ID to be concatenated. Returns: TMD, Ticket (if available) plus all the contents (all raw, big endian). TODO: allow downloading content for other systems (Wii U, DSi + 3DS)
