ZSNES sucks with Satellaview ROMs in general, and higan is VERY picky because it will ONLY load them in conjunction with the BS-X ROM. Rest assured, though, this is one of the games I've actually verified the dump of, so it's good.
So I should ask, what is your emulator setup for higan? My first guess would be that you don't even have the "BS-X" ROM, so check how higan links with that and then find it, and then try loading Shubibinman Zero.
