It's not Contra, but here's a pretty amazing Final Fantasy 7 remake using LBP. Now there was one really bad FF7 remake that is honestly nothing like the game. This game is pretty spot on, though it unfortunately only from the beginning of the game to the part after Aerith's Church. It even includes an ATB system.

I recorded it put it up on Youtube to memorialize it, sad that this game didn't get covered by the news outlets and the others did. This remake is amazingly well done. Some may even consider it better than Square Enix's remake :P. I liked SE remake.
