Dance Dance Revolution for your TI-83/84

I remember back in the day when I spent many a period settling down in the back and playing Tetris on my TI-85. It was most enjoyable. Now, someone has gone and ported DDR to the TI. Another great game.
Unfortunately you’d probably get busted for getting up and dancing to your TI during class. Just kidding.. there’s no dance pad.
