On Sonic Heroes with Team Chaotix in Mystic Mansion I can't get past the bit were your'e in a circular room and there's a door and above the door is a target switch and when you enter the room
there is a locked up upsidown switch.How can I get past the room?
Hit the target with Thunder Shoot (you need to hit it from a distance, otherwise it will start spinning and you won't be able to touch it) to open the door. Use the switch within and the circular hallway will now have an exit.
