When your playing as shadow and just started the game in one of his levels radical highway in the when you first come in o down the rail up the spring and run across the road for a while and soon you will come to a ramp run off it and either climb the or take the crain and go on to another platform at the top of the boxes [or crain] then go forward there should be a set of springs jump on them and when your in the air from the way you see in the air go left if you went the right way there should be a big spinning thing in the middle of the road press B to summersault under it and then the road should just end with a bunch of rings going across go to the edge of the road start spinning and right before you fall off jump and you should go flying over the edge and on to the other side with another pair of springs go off them and go forward into the glowing green circle with the ring in it and there you go you have the flame ring and you didn't even need the ring dash
note: you can do this the first time you go to radical highway
