Someone went and did it, implementing what I've called the "TV tuner" method (and others have called "reverse emulating") to play Grand Theft Auto 5 on a PlayStation console, using a custom cartridge in an unmodified Game Boy system as input and display.

Grand Theft Auto 5 played through a GB

I'm glad the title is 'played through' and not 'played on', as the GB's being used as a pass-through device and as a remote control.
I have an ASD, so empathy is not natural for me. If I hurt you, I apologise.
