Verse the Deathegg robot more than once
This is not much of a cheat but I figured this glitch out while I was playing.
Step 1. Activate level select(up3 down3 left right left right) than hold y and press start.
Step 2. Activate the debug and chaos emerald cheats.
Step 3. Go straight to the Deathegg map and verse silver sonic. It will be much easier in super form.
Step 4. This is the hard part. Sometimes it dosen't work. Beat the Deathegg boss. Right when super knuckles runs to get out and you leave the battle, there will be an explosion gaining on you. Turn into a ring or ring box and fly back to the place that you beat the Deathegg. He might be back there and you can battle him again, WITH EXPLOSIONS ALL FALOWING YOU! AWESOME!
