Link: Mega Man 9 Wii Rom

Distributing or downloading ROMs of copyrighted games without permission is generally considered piracy. It deprives game developers and publishers of revenue and undermines the value of their creative work. Legitimate ways to play Mega Man 9, such as purchasing it on the Wii Shop Channel or through re-release on modern platforms, support the gaming industry and ensure that creators can continue to produce innovative content.
