So I was looking at tasvideos.org, like I do everyday, and I noticed this newest entry... I have to say that this RAM manipulation made my jaw drop. Look by yourself, and enjoy the show -- really cool stuff done here! There is no romhacking nor gamegenie cheats involved. Just a total memory control done with a very specific manipulation. This has been done with Super Mario World and Pokémon Yellow before. But what about a NES game? Enjoy!
