Like adult Rydia’s last minute entrance with the Mist dragon, Final Fantasy IV suddenly shows up as a PlayStation Network download. You can defeat the Four Fiends and see Cecil transform from a Dark Knight to a Paladin on PS3 or PSP. Although, if you want to play Final Fantasy IV on PSP you might want to check out Final Fantasy IV: The Complete Collection which has enhanced sprites and The After Years saga instead.
The version available on Game Archives is the PsOne release, which is actually a port of the Super Nintendo game with a new opening video. Final Fantasy IV costs 1,200 yen ($15).
