I know some people still enjoy a classic like Final Fantasy VII for the PC but it doesn't always work so well for everyone. Here's a package of patches, fixes and cracks to make it work perfectly and without having to change discs.

For the crack, you will need to copy the "movies" folder from each disc to the game's "data" folder before applying the crack, afterwards the game will work without needing discs and should work perfectly.
