"This is a complete hack of Super Mario Bros 3, featuring 4 new worlds and 1 secret world! All worlds are filled with new levels, new graphics, new asm mods and more!

Just play it and you’ll discover the new things by yourself :)"

Old hack is OLD. Released back in 2005, this is one of the first hacks to use ASM modifications, along with some interesting new stuff at that time.

I did play this hack, and made videos of it, too.
But the quality of those is... VERY BAD. So here it is again!
World 2 here! World 3 Soon!
