If you hack, you can do anything
Now Again, we have a couple of videos coming from Sonic Retro boards. The first one shows the game latest unlockable, unlocked via hacking, instead of completing the tasks you need to in order to unlock it legally in the game. As yesterday’s report said, this is the “Segabot”.
The second video shows one of the leftover characters, Chicken Leg. It’s probably leftover data from the first ASR, since it was already known that they tested a Chicken Leg as Gillius vehicle there before getting him out the game. The transformations are incomplete in this model, so it shows that it’s really not meant to run in this game.
You can see both down below.
