I found a workaround with the .srm files.

Open the game you want to use it on before copying over your saved data. Try to open a saved game. This creates a .srm file associated with the game file. Overwrite the .srm file with the desiredsave file.

I do not know why this works. It does though.

@Davedrumx I know this is quite old topic but I believe the thing you are.. or atleast were looking for is SBI Files for certain PS1 Pal games. They can be downloaded from psxdatacenter and possibly from other places too like internet archive.

@crickentine I share your enthusiasm about FFVII but I'd disagree with the game getting good after Midgar. The game is already brilliant during Midgar so if it doesn't take hold of you then, it probably never will.
The only thing that does get better is the combat (more varied and difficult).

@miclamcm your welcome. Enjoy some awesome ff7 goodness.
