There are 130 total Emblems in the game and in order to obtain them all you must:
- Complete all Action Stages (Levels A, B, and C)
- Complete all Character’s Adventures
- Complete Super Sonic's Adventure
- Complete all Sub-Games (Level A and B)
- Collect all 12 Hidden Emblems throughout the Adventure Fields.
- Win all Chao Jewel races
All of these requirements have already been described further above. If you have been following the guide then you should have this one already in the bag. Once your Emblem count reaches 130, this achievement will unlock. If you need to check you emblem count go to the main menu, go to Trial, then Emblem Results.
Note: The Super Sonic adventure is very easy to complete. You will first go to Angel Island to see Knuckles then afterward visit the forest at Mystic Ruins. There will be many cut scenes but once you reach Perfect Chaos simply run up to his body and you will swirl around within him and then burst out of his head, this is how you attack him. Watch out for his projectiles and use speed ramps when you can.
