[SNES] Bubsy Prototype

I received this prototype of Bubsy for the SNES a week ago. It appears that the program sections of the binary have some differences compared to the final version, but the gameplay is essentially identical to the released version. Maybe other people can have more luck at figuring it out?

Thanks for the share

 

Is this the one that was recently on ebay? Thanks for dumping this for everyone!
