With compatible gb games of course???
Use to always play my old game boy games with the super gameboy adaptor on my snes. Even some gcg games worked like pokemon gold/silver.
Many games had their own borders around the screen plus had games playable in colours so I hope there is a super game boy for snes emulator which can play gb games on it (or maybe even just a super game boy emulator with no need to use it with a snes one??)
