We've seen plenty of games attempt to take on the might of Super Smash Bros. over the years, but few have been as unique as Super Tilt Bro. on the NES.
For starters, yes, it's a NES game. Secondly, the cartridge actually has a Wi-Fi chip inside so you can play online with other people. On your NES.
This open-source fighting title is still in development and the cart itself is in the prototype stage, but what we've seen so far is quite exciting from a technical perspective... could other cart-based consoles see online play added via similar means?
