It ensured that whether you were standing in an arcade or sitting on a couch, the hardware spoke the same language: the language of high-fidelity 2D gaming. The Neo Geo BIOS is not an operating

Physically, the motherboards were different, but the BIOS was the key differentiator: SNK manufactured two versions of the hardware: the
