ZSNES board

First off, i have a working super gameboy rom(from *link removed*), and second , couldn't it be done in a way similar to sonic and kuckles with sonic2/3 on sega.

Could it be possible to create a hack program that would merge the GB rom with the super gameboy rom and create one combo snes rom?

defently they should add super game boy support
the rom can be found many places - iused rombay.com
the rom doesn't load gameboy games by itself
there would need to be a feature in the emulator where the SGB rom could be selected and then a load GB rom option in file menu

i can find a rom 4 it but the rom can't play gameboy games
is there a way the rom could be used to emeulate this on zsnes
and to be authentic

ps: some GB/GBC games have special features on snes with super game boy
