While you're at it, could check out the GBA ports of some of them too, Visual Boy Advance is the GBA emulator of choice.
The original NES FF2 is nearly unplayable, while the GBA one isn't too bad.
GBA FF4 is closer to the original Japanese version plus some extra stuff in the finale, but there's a few game-breaking bugs in the battle system that *** with your turns. Probably should go with the DS remake.
GBA FF5 has an official translation (and imo, genuinely funny dialogue) and some bonus stuff like an extra dungeon with more jobs.
No idea about GBA FF6 aside from a less memorable translation, could probably play the SNES one just fine.
