Copying of any Nintendo game is illegal and is strictly prohibited by domestic and international property laws. We oughtta know, we paid some damned big money to get it that way. Now, if you happen to be just backing up your own games, which if you paid for the game intellectual property law also says you therefore bought a license to it and so maybe the truth is the Court's would wind up siding with you instead of us, we'll just ignore you but keep telling everyone else it's illegal. And, if you have copies of games from our older systems like NES and SNES, we know the chances of getting the US attorney's office to prosecute you is just about nil, and sueing wouldn't do a lot of good either since we're not losing any profits...we don't even sell games for those systems anymore. So, we'll ignore you too,but it's still illegal, darnit. And if you set up a website that offers roms for download, then we'll call your ISP and scare the bejeezus out of them and you'll have to shut down your page. Daggonit. We mean business! We're not fooling around here!
