Sega released a number of arcade games using something called the "super scaler" technology - Out Run, Hang On, and After Burner are great examples of this - but perhaps the most legendary of these games was Space Harrier. The game was later released on Sega Master System with 3-D Glasses support, and now it will once again get the 3D treatment as it is released as a 3D classic on the Nintendo 3DS eShop.
It looks like an upgraded version and it supports widescreen, and it is also said that this is the first of several Sega 3D Classics.
