There once was something called a Super GameBoy, which was a cartridge adapter for GameBoy games to play via your SNES. It came out in 1994.

But if you wanted to play gameboy games on TV and on the go, you'd need to own a SNES, Super GameBoy and a GameBoy.

The SNES also couldn't play GameBoy games, the Super GameBoy was really just an entire gameboy in a cartridge formfactor.
