I like my Hyperkin Retron Sq.

The Hyperkin Retron Sq is a nice enough for playing Gameboy and Gameboy Color cartridges.

It’s actually fine for lots of Gameboy Advance games, as well.

But, by virtually every account I have seen, the Analogue Pocket is a much better option, for about the same price. If I had been aware of the Analogue Pocket, I would have bought it, instead, or at least first.
