Free online games, played right in the browser — no downloads, no sign-ups, no ads. Every game is fully playable free; the console just forgets everything when you leave. That's what the Memory Card is for.
Somebody in the back room did things to this memory card that the manufacturer
would not approve of. It works in all eight cartridges at once. It will work in the next ones too.
Nothing. That's the design. Free players get every game, every mechanic, the whole arcade — and the moment you close the tab, the console wipes itself like it never met you. High score? Gone. Unlocked character? Gone. The run of your life? Especially gone.
