Question about MU Classic Game console with 600 games and 2 game controllers

Unfortunately, our research has not yielded any information on this.

The number of buttons on the controllers alone makes it impossible for SNES games to be on them.

I doubt very much that Nintendo games are on it, it would be highly illegal and Nintendo would immediately take it out of sale with a lawsuit. Such "consoles should not be bought. There are better alternatives, be it with a Rasperry Pi (which can emulate everything up to and including the n64 generation) or with the original Nintendo Classic.
