Just a note to everyone: Sometimes the save games do not vary across the different regions a game is released in. So if you find a save to a game that is not of your game's region, its still worth trying.
But in the case of FFX, since the game was changed between a few releases the saves are probably not cross compatible.
Vanit is correct, saves from one European version (eg UK) will not work on anouther (Spanish / French etc). Perhaps if you could provide a game serial (on the side of the box - looks like SLES / SCES / SLUS / SCED / SLPM with 5 numbers after it). Or provide us with the location you bought the game from.
Regardless, here is a small selection of saves I use from the UK version Final Fantasy X [SCES 50490] (E)
