While waiting for CS5 to redownload, I finally decided to try out a little slice of retro goodness. Exploding Rabbit on Newgrounds created this retro mashup that lets you play the original Super Mario Bros as other characters from the 8-bit era (Samus, Simon Belmont, Contra Guy, etc). You can clearly see it was a labor of love and turned out awesome. Now, if I could only get my xbox controller to work with the game, I might not die so much.
Check it out here.
