If you’ve always wondered if Super Mario World could have been done on the Original Nes, you’re about to have your answer. Someone has managed to cram the complete game into an 8 bit rom and the game actually runs very well and looks similar to the original game.

The rom plays flawlessly and has visuals resembling those of Super Mario Bros. 3. Of course, some features have been removed or modified for the sake of having the game run smoothly.
