Garfield: Lost Levels

Does anyone know if the Rom dump actually exists for this game? I am NOT asking for the rom, or any links. I just want to know if it even exists.

For those of you who don't know, this was another one of those SegaChannel exclsives. It had about 5 levels I think that were cut from the final game. Some of them were really interesting, like the space level (I think this was just the beta...).
