To get Jewel Chao for Dreamcast's SA2, go here and have your VMU ready. It needs 6 blocks for download, and it can't have Chao Adventure or Chao Adventure 2 on. And it will be deleted once it gets transferred.
Chao:
Black Chao (With Highlights)
The rare highlighted Black Chao is ready for trade! Plus, try to make it look like... him... *shiver*
Cost: FREE!
Silver Chao
This Chao is the cheapest Jewel Chao around! I think of it as a squishy marshmallow.
Cost: 5 Emblems
Gold Chao
This Chao is pretty awesome. It's 1,000 Rings on the GBA, but it's only 10 Emblems for DC.
Cost: 10 Emblems
Ruby Chao, Sapphire Chao, Amethyst Chao, Emerald Chao
Really awesome Chao! I wonder which one looks best as a Neutral Chaos Chao...
Cost: 20 Emblems for each Chao
Moon Chao
One of the most rare Chao in existence! Without AR, it's just a myth. What shall you make of this rare Chao?
Cost: 30 Emblems
By the way, Chao on the Dreamcast don't last long unlike SA2B's Chao. I think it only lasts about 5 Dreamcast hours.
