PSP, came out in the west as Final Fantasy Complete Collection, with the original FF 4 game (with these touched up sprites), a middle game (Prelude) that bridges this to the final game in this set, The After Years. IMO this is the best version of this game out there, even better than the DS version, which for some reason Square felt needed a 3D touchup (it didn't, but it has voice acting for some parts, the only advantage it has).
