Fun Super Mario Bros. hacks

[treismac]

I was looking for some recommendations for some kickass Super Mario Bros. hacks. Any suggestions? If you suggest something, say why it is a worthwhile hack, too? Is it fun? Bizarre? Challenging?

Thanks!

Super Mario Unlimited, because it has great graphics and level design.

I quite enjoy Super Mario XXXX.

Sweet!  Thanks for the recommendations.  Let me recommend the Super Mario Bros. Special hack based on the Hudson Soft version of the game.
