I don't know if anyone else is experiencing this problem..... But during battle I am unable to use ANYTHING such as magic, gfs, and items! the only option I'm able to do it attack and its getting REALLY ANNOYING cause I'm unable to play the game because of that!
Do you have a GF equipped? If so, did you remember to set your commands onto your character? Remember that after having a GF equipped, you must then manually put the Draw, Magic, GF, and Item command onto your menu, in order to use it in battle.
Great that you immediately knew he was talking about FFVIII.
