Sonic Advance 3 - Sonic & Sonic

This was a stupid thing I did for the Moogle Cavern forum a long time ago when there was such a place. Somehow or another I was reminded of this, found I still had my notes, and replicated it. For the tech-savvy, you can set RAM addresses 3004503 - 3004506 all to the same value when selecting a character (0 = Sonic, 1 = Tails, 2 = Knuckles, 3 = Cream, 4 = Amy) and get ... this.
