What is "solvalou"

is a first-person shooter arcade game which was released by Namco in 1991 only in Japan; it runs on Namco System 21 ("Polygonizer") hardware, which displayed the game very smoothly with flat shaded polygons. The game is controlled with an analog (vertically-reversed) joystick with two buttons - one for firing and the other for bombing. It is also the third title in the Xevious series.

Solvalou is also the name of the ship that the player controls in all three games, as well as the fourth and fifth ones, Xevious 3D/G and Xevious Arrangement (both 1995); its name was also borrowed as a fictional company brand in the 4th Ridge Racer game, Ridge Racer Revolution, for an elite Italian racing team which raced in distinct silver and navy blue livery similar to their namesake. It also later appeared in Tekken 5: Dark Resurrection as Jack 5's customization.

The game was released for the Nintendo's Wii Virtual Console service in Japan on March 26, 2009, and is one of the first Virtual Console titles to make use of the Wii Remote's pointer (as it is the most accurate way to replicate the game's 360-degree joystick).
