"UPDATE: Appearnly this app is no longer in the Chrome Store so. Yea... Gotta hate it when they pull awesome stuff.

Not sure if this works on the normal Chrome, but works fine in the Google Chrome Canary Build. Anyhow, just head on over to the Google Chrome Web Store, search for Mario Bros Crossover (hacked). There is two, one non-hacked, and the other.. of course is Hacked. It runs pretty well, and has Characters from other games. Give it a try :p"
