Mario 25: Skuf Mario (Russian hack)

Mario 25: Skuf Mario is a fan-made ROM hack of the cult Super Mario Bros. for the NES (Dendy), created by the Russian retro gaming community in 2025. The in-game text is in Russian.

In this hack Mario has turned into a "skuf", a lazy middle-aged guy from Russian internet slang, and the levels, graphics and jokes have been reworked to match. The gameplay stays the same: run, jump, stomp on enemies and get to the end of each level.

It is a funny curiosity, especially for those who understand Russian internet humor.
