No I beat sonic heroes And NO CHAO WORLD.
Play a level, get the chao key by breaking open a chao box and finish the level.

No, but I do believe a Chao does make a cameo in Sonic Rush when you are about to play 2P with a friend.
No
Usually, you find the Lost Chaos where you do Mystic Melody or whatever it is (You know, where you play the flute at the 'old ruins' like sonic says). You play the flute and go on the obstacles and you see a chao!!! But if you get the chao, it does NOT go to your Chao Garden.
The chao who won the race will play with them randomly.
No but you can if you hack or play the dreamcast sonic advenure Dx
Its a hack or a cheat that lets you.
The answer if you can texture hack so then you can play hyper sonic
you have to buy sonic adventure dx, sonic adventure 2 battle, or pantasy star online. sonic advenure dx and sonic 2 battle are for gamecube or you can play them on wii with a controller and a memory card and a gameboy cable.
Sonic Heroes
I'm afraid there has been no hearing of Sonic Heroes 2. But he will show up in multiplayer mode in Sonic and the Black Knight if you play it.
