Pixel art is not really advised for a company logo.
I'd probably do a silhouette of it in vector, with some steam-lines, and simple (diagonal) detail. (Maybe add a d-pad and buttons onto it to make you think of games, rather than green squares. Or put it the melonpan on a GB cart label.
It's pretty indistinct, a blob-ish shape, and not that well known here (as say a croissant or a doughnut) so steam lines might help describe it as a baked..thing. (Removing it's colour-identity by giving it a GB palette is probably not helping).
