The site itself, along with many others, claim that it is legal; however, I just want to be sure. From what I've heard, claims as to how it is legal include: they own the games, so it's ok; and the products or "games" are not being produced anymore (products or games being N64 and Playstation 1 games), so they've been given permission to put there games up as free downloads or whatever you call it.
Thanks for your timeAccording to Mr. Oppenhuizen's answer, I now see that downloading the ROM and IOS files are probably illegal. However, if I already owned a copy of one of the games that I'm downloading, would that still be illegal? After all, I already own the copy, I'm just making it available to play on my computer. If that's still illegal, correct me. Thanks
