FF6, in the original jap version with translation patch, is one of the first games I decided to play on PocketSnes, where it plays satisfactorily.
But I must say that I was quickly turned down by the game itself: the story and setting are ridiculous (FF4 was much better!), and the random battles are annoying. I hate how FF rpgs just try to "innovate" battles with stupid variants (like beasts etc.), but they remain invariably boring...
I soon stopped and moved on to Front Mission.
