could do it legend of dragoon style/ff7. I had a caterpillar system in one of my rpg maker games, I think it was for xp though (or vx), not 2k3. it was flawless too, but I designed my levels with the system in mind, you cant really do that with a good portion of these chrono games seeing as how some of the areas are taken from an already made game. the best I could tell you is to emulate it as close to CT as possible, the speed of movement and milliseconds of lag the the other persons take before following the leader.
