I haven't 200'd a single Arcade game yet. I'm really close on Sonic 1 & 3 though. I need the achievement for finishing Sonic 1 in under 40 minutes (do I have to get all the Emeralds for that btw?) and for Sonic 3 I just need to finish the final zone, and get all 7 Emeralds on my next playthrough. I just haven't found the motivation to get either of these yet ):
