Savestates included are for the FCEU Emulator. If you would like to download this game, click here for the patch. If you would rather have the rom itself, click here instead. If you are interested in viewing screenshots of the entire game, click here. There are currently no walkthroughs or cheats available, other than savestate files. There is a sequel to this version of Super Mario Bros called Jerry's Remix 2. Its levels are a little less weird and more challenging.
