Emblem Collector - 40G (Original Achievement)
Difficulty: 3/10 (Will take a lot of time)
This achievement will pop up over time, simply do all 5 missions for each level and regardless if you get an A,B,C,D, or E rank, you WILL get the emblem for clearing the mission. This is also a good way of sizing up a mission's enemies or ring locations for A Ranks. There are 3 emblems for Kart Racing, 5 for Chao Races, 4 for Chao Karate, and 3 for Boss Rushes. However these require a bit more effort so I'd suggest you play missions instead.
