If this isn't the thousandth thread about this. I know I may sound stupid, but a decent 8-way pad isn't too expensive. It changed things for me, by the way. If you can't get one, the best advice I can give you is to do some training on a game that lets you walk diagonally (I don't remember if FF VI does) with your pad by pressing both buttons at once. There are people who claim to be able to do blitzes eve with a computer keyboard, so with a D-pad it should be fully possible.
