on kazaa, someone ported ffx to pc. compressed, its about 700 megs. so i recommend having at least 2 gigs of harddrive space (for the game and save files), a processor with a speed of 1.8 or higher, 32 bit graphics card, and a decent good sound card. that should be it. i downloaded it, and its actually pretty decent. no emulator is required, but a version with an emulator is about 300 megs, but is worse quality.
