Solvalou is the name of the ship that the player controls in all five games, including the later Xevious 3D/G and Xevious Arrangement. Solvalou is also borrowed as a fictional company brand in the 4th Ridge Racer game, for an elite Italian racing team who race in distinct silver and navy blue livery similar to their namesake. It later appeared in Tekken 5: Dark Resurrection as Jack 5's customizations.
The game was released for the Nintendo's 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.
The arcade version of Solvalou runs on the Namco System 21 hardware, also called Polygonizer, which displays the game very smoothly with flat shaded polygons. The game is controlled with an analog pilot joystick with two buttons; one for fire and the other for bombing.
There are two cabinets for Solvalou. The larger, sit-in, cabinet has a concave mirror which reflects the inverted image of a monitor placed above the player's head. The other one is an upright cabinet with a 20 inch monitor.
