This is a hack replacing Sonic the Hedgehog with Chip McCallahan from Chips Challenge. Graphics and sound (except an irritating noise from Chip, presumably) are the same as Sonic 1. Chip can do nothing other than have weak jumping height and slow movement. He won't be able to open any television boxes, and he will die by taking damage, even if he has rings. In fact, when he takes damage, a message appears telling you to be wary of something and the level restarts, although he won't lose a life. Also, in Labyrinth Zone, Chip can't enter water at all. There is no way you can complete a level let alone the whole game, due to Chips weaknesses. If you wish to play as Chip in other levels, the level select cheat must be activated, but his level activity will be very short-lived. The thing that's really irritating is that in the first level of Green Hill Zone, Chip can't even get past the first Motobug, therefore failing the level. Motobug also has his own Sonic 1 hack and can't complete the game without cheats, but his jumping is better in comparison with Chip's, so can access more of a level. Overall this has to be ranked as one of the most frustrating and pointless Sonic hacks ever created, and personally I don't see myself playing this on a regular basis, if at all.
