We've been diverging lately into video game history and ephemera in these VC Advantage columns, because those are usually a lot more interesting than just plain old cheats, while keeping in the spirit of extending the enjoyment of games through secrets. But sometimes it's nice to get back to the original stated purpose of presenting codes for Virtual Console games as if we were writing a column in an old gaming magazine.
Mega Turrican seems like an excellent candidate for this treatment, because it is hard as all get out. While previous entries in the franchise involved huge, maze-like levels, Mega Turrican is basically Contra but faster (and with backgrounds that don't contrast enough with the enemies) -- a straightforward left-to-right run-and-gun. And that is almost universal code for "punishingly hard game whose first level you will see about fifty thousand times."
With that in mind, an invincibility cheat seems like a perfectly relevant and helpful thing to offer. It couldn't be easier to pull off, either: just pause the game and hit A, A, A, B, B, B, A, A, A. You don't even have to write this one down! You can also skip a level by hitting right, left, down, right, and then B while paused. And now you can pretend to be successful while playing Mega Turrican!
