These are Comix Zone, Mega Man: The Wily Wars, Target Earth and Zero Wing.
Mega Man: The Wily Wars from 1994 sees the evil Dr Wily attempt to defeat Mega Man (something we won’t let happen) in a compilation of the first three Mega Man games.
Nintendo has announced the arrival of four more titles from the Mega Drive for Switch Online.
Then, when players have a completed save file, they will be able to tackle the newly added game called Wily Tower.
