Super Mario Bros. is a platforming game for the Nintendo Entertainment System released in 1985. When Bowser invades the Mushroom Kingdom, it's up to Mario to stop him and save the Princess.

This is an update to Szemigi's old Super Mario Bros 3.: The Forgotten Worlds SMB1 NES hack. Thanks to his permission, the hack was rebuilt and updated. All levels from the original hack were recreated with ALXR's Great SMB Editor and a hex editor - they had to be ported to SMB2j first, then back to SMB1 again. Gimmicks like 2-player mode being removed in favor of the "Luigi power-up" or blue enemies were cut, making this more similar to the original SMB/SMB2j games. Graphics remain unchanged. Special thanks to StudsX for the title screen and Famulator64 for his SMB2j cloud patch.

It was thought that Bowser is dead and that no evil can happen anymore. However, his ghost came back and created four mysterious worlds. Now it's up to Mario and Luigi to rescue Peach who has been kept hostage by Bowser's Ghost in a fortress in the sky. Will they defeat the spirits and bring the world back to peace?
