NIS Downloader

This is NISD (Nintendo IOS System Downloader I know you guys must be thinking this is a NUSD rip-off, it's not, I could even say it is better than NUSD except I don't think it is as updated as much as NUSD. You can download channels, IOSs, and System Menus. It basically is the same thing as NUSD except you can SEE what IOS, channel, or SM you want. It also gives you the 000000X000000X code so you can use NUSD to download the latest version of an IOS. It downloads all IOSs in wad format.
