Play Super Mario 4 (SMB1 Hack) Online
Another bootleg Mario game with new enemies, stages, and visual changes.

Game Overview
Super Mario 4 (SMB1 Hack) is one of those weird NES bootlegs that remixes the original game in strange ways. At first glance, it looks familiar—same sprites, same jumping physics—but then you notice the enemies are different, the levels twist in unexpected ways, and some power-ups behave oddly.
I remember jumping into what should’ve been a standard underground level, only to find the platforms rearranged and some bizarre new enemy bouncing around. It keeps that classic Mario feel but throws in enough curveballs to make you pay attention. The visuals are mostly the same, just tweaked—like someone took the original and ran it through a filter.
If you’ve played the original to death, Super Mario 4 (SMB1 Hack) gives you something just different enough to feel fresh without losing what made the first game work.
