Downloading Final Fantasy VII

Option #1: Torrents
I think this is the easiest and most convenient option. The torrent program that most people seem to prefer is uTorrent. Once you download the torrent program, you can then partake in downloading torrent files. Torrents aren't as popular as they used to be, but there's one good active torrent that still remains:

Bundle containing FF 7-9, Anthology, Origins, Chronicles, Tactics (all NTSC) - 5.7 GB

Option #2: ROM Websites
A couple ROM sites in my links have PlayStation 1 games. Those websites, though, are kind of annoying to browse with all the ads. I still recommend the torrent option above.

Option #3: Reddit
You can try doing a Google search for “reddit download playstation isos” or “reddit download psx isos”, and search Reddit threads to see if anyone posted some good places to download PlayStation 1 games.

Playing Final Fantasy VII on your Computer

You can play Final Fantasy VII right on your computer with a Playstation (PS1) emulator. I have the best ones for download in my emulators page. And if you need assistance with the Playstation emulator, check out my emulation help site, Video Game Emulation for Newbies, for help.
