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.

Another follow up. This time, Worlds A to D. The princess has been kidnapped again and Mario has to traverse 4 new worlds of Jeansowaty's Land. Again, this is heavily inspired by SMB2j. Worlds A-D work as new worlds and Bowser also changes to different things depending on the world. In World A, he disappears. Don't try killing him in World B! The game will freeze! If a fix for this will be found, I'll update the file. In World C, he turns into a lift and in World D... so this wasn't the original Bowser? Who kidnapped Peach? So many questions yet not as many answers... in World D he turns into a red Koopa Troopa. The level design has much improved compared to the original Jeansowaty Levels and seems a lot more unique. Special thanks go to Insectduel for his After World 8 hack which served as a good learning grounds and Famulator64 for his SMB2j cloud patch.
