I already wrote about the NES Mini hack that adds more games to the system. But now you can add even more games, thanks to a new hack.
This hack adds every NES game out there, bringing the total of 700! Yes, the full NES game library can be added to the NES Mini.
This hack is more difficult, but there is a guide that shows how to add the games and like the previous hack, you will need the NES Mini pimp tool.
