The latest update for the Wii U added virtual console feature to the system. There are a bunch of games coming to it and Nintendo has released a new trailer what games will be available.
NES and SNES games can be played on the Wii U Gamepad and players will also be able to create restore points. The video tells you all that you need anyway. It shows easy ways of creating and using restore points so that you can start just before you died and attempt that section again.
It was something that was sorely needed in a Mario game though. Check out the game list below:
Mega Man
Xevious
Balloon Fight
Super Mario Bros
Street Fighter II
Pac-Man
Super Ghouls ‘n Ghosts
The Legend of Zelda: A Link to the Past
