Super Mario Bros.: SMB Instant Death Spike patch is a modification for the Nintendo Entertainment System that alters specific orange mushroom levels by replacing standard mushroom platforms with spikes, which cause instant death for Mario regardless of his state. Coins are converted to downward spikes, while other levels retain their original functionality and appearance. This patch is designed for the US and JP versions of the game.
This patch, when it's an orange mushroom level, will replace existing mushroom platforms to up spikes and coins to down spikes. Mario will die upon interacting with these, no matter what state he is in, and it's custom-coloured. Any other level outside this area type will function and look normally.
Side effects: In 1-1, the first enemy is dragged to the third page of the room, near the first pipe.
