Making a multicart of bB games, using bB, isn't as easy as it would seem - unless the games were designed for said cart to begin with.
One of the more likely reasons it won't work is because sprite space is so limited - is there more than 2.5k of sprite data in total? Remember all that stuff gets stuck in the last bank when you compile.
