Bilger Sup 400 Games 3" Mini Atari Retro Game Nostalgia Games, White, bilger453

The "Sup 400" is a prominent example of a "Famiclone"—a clone of the original Nintendo Entertainment System (NES) / Famicom hardware shrunken down into a Game Boy-style pocket shell. Despite being marketed under various brand names like Bilger or using keywords like "Atari," it is entirely built around running 8-bit NES-era games.
