So unless you're ready to go full blast and do some hardcore cheating, I would suggest just leaving this option alone until all you have left to learn is Magic. Community Hub FINAL FANTASY The original FINAL FANTASY comes to life with completely new graphics and audio A remodeled 2D take on the first game in the world-renowned FINAL FANTASY series Enjoy the timeless story told through charming retro graphics. I used this on Strago to learn all of his Blue Magic and the achievement didn't pop. It unlocked the achievements for Cyan, Sabin and Gau's abilities when I used it on the Veldt in Sabin's scenario.

It works on Mog's Dances as well but be warned, you may need to use SAM to manually unlock certain achievements tied with learning everyone's abilities. This works on EVERYTHING, including Gau's Rages and Strago's Blue Magic. So either accept the fact that you've just botched your save file early on or don't use this until the very end of the game. There is no way to segregate these options either, it's all or nothing.

Basically turn this on, fight a single battle and whatever character is in that battle will learn all of their special abilities including all the Magic in the game.
