One of the smaller Gameboy multicarts and one that features a reset button, let's take a look

4 games, reset button, this means that this game has no menu. You basically use the little reset button to toggle between games. I have seen early pirate carts with as many as 12 or 16 games without a menu, but using this small button to toggle between, at 16 games it gets tedious though.

So, let's see "all" the games included on this 4 in 1

Tennis
Battle City
Tetris
Heiankyo Alien

And it delivers what's shown on the label, nothing more, nothing less and with very little effort, no menu, just reset your way to the game you want.
