Play Super Mario DX Online

Summary

Super Mario DX pops up on the Game Boy Advance as an unlicensed curiosity that feels oddly at home among the console’s library. Sintax, the studio behind a handful of GBA platformers, repurposed its own engine for this title, giving it the same tight controls and sprite handling you’d expect from their other releases. The result is a Mario‑styled adventure that slides smoothly despite its unofficial status, and its familiar engine makes the level design feel both nostalgic and surprisingly polished.
