If you download someone else’s copy that’s identical to your own copy you purchased, you’ve done nothing wrong (the other person might have)

Note, this law above does not mean its legally right to download and use someone else copy. And if its wrong or not. That was just your personal interpretation. The law just tells us what is illegal, not what is legally right. If you say someone you are not allowed to steal an apple, that does not mean he is allowed to steal an orange.

And downloading someone else’s copy is not identical to your own copy, its never. Edit: However I am not sure about downloadable games, as they have to be identical I guess. But then, its not your personal backup copy of a cart then.

If the person who gives a reproduction (a backup copy) away makes something illegal, then the entire operation of downloading is illegal. Because without your downloading, he could not give it to you. Someone has to download in order to make it illegal, so you, who download the ROM is part of the entire operation to make it possible. That’s the problem. And it does not matter if you knew or not; the operation was illegal and you was part of it.

See? Things are not that easy!
