The Super Mario Bros. Co-Op Coin Challenge
(Coins Hurt Mario But He Can Jump On Them!)

The Mushroom Kingdom has fallen under a spell, all coins are now enemies and will hurt Mario!
Mario will bounce on the coins just like regular enemies, but watch out! The coins are cursed and strange things will happen if you touch them.
Luckily Luigi is immune to the curse and can help his brother to navigate through the dangers. There are however lots of other enemies in disguise, camouflaged into powerups trying their best to make life hard for our heroes.  

The hack is built upon the two player hack by CorpseGrinder and Ti. Just patch the original version of Super Mario Bros. with the ips provided in this download. 

Levels, graphics and music by Nesdraug. 
Special thanks to StudsX for adding the new sound engine to the hack and updating the boss fight and the boss music.
