hyper shadow chao

hey in sonic adventure 2 battle i have been trying to raise a shadow choa the passed 2 years or so and i havnt had that much luck, though at one point my chao got three spikes on the back of his head and green stripes for only a couple days. he then turned into a dark chao with no legs, i did research and it said a shiny black ig is needed and i didnt use that, so i did more research and found out you cant get a shiney black egg even though it said that you need it on the gamecube section on gamewinners I NEED HELP

Raise you're newly hatched egg as a running choa. It has to be one of the starter type egg chaos though.
Get it to about 0100 in run at least and keep everything else 0, and stamina you can raise all you want it doesn't affect the look. DO NOT get 99 in running. usually 20 works fine.
After you're chao evolves into a dark chao, it should look like shadow but with green stripes under the spikes.
once it hits about age 3 start giving it cheetahs or bunnies until it turns red. because they give +40 in running compared to green chaos drives with +24
the you'll have a shadow chao guarantee. i just made one yesterday.
