Notes : Sega had always envisioned their 3D system to be textured, never just flat shaded 3D, so with this in mind they kept their relation going with GEA (now known as Martin Marietta after being bought by them in 1993) and worked with SEGA to upgrade the Model 1 graphics, including the new texture mapping features among other effects.
