An Ashens tat-video 'favourite' of old the Hartung Game Master was aimed at potential buyers of the original Game Boy, offering a cheaper solution. It was cheaper for good reason. MAME's emulation of it has always been quite poor with most games not really being playable, but happppp recently updated it, adding the proper LCD controllers and fixing some CPU core bugs, bringing it to a state comparable with original hardware.
This video shows all the known software for the system, I've attempted to play until at least the 2nd level in each game where I could. There's no commentary, only the beautiful sounds of the games in question. This progress will be in MAME 0.248.

There are rumours of a game called S-Race, but no proof of it existing has ever been found.
