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.
Emulators : Nebula (2D and Audio)

《梦游美国》,MODEL2的首发作品,名越稔洋开发,光吉猛修作曲,以佛罗里达州地通那大赛为题材。每秒30万多边形、60帧刷新率、带回力效果的方向盘、金属的档杆,40辆赛车同场追逐、壮观的翻车镜头、车体的破损效果、热血沸腾的音乐——与MODEL2基板本身一样,这就是个人心目中街机赛车游戏的王者!1995.4.1移植到SS,也是该主机首个MODEL2的移植作。虽然在多边形数目、帧数等方面与街机版相去甚远,整体移植度不到70%,也卖了60万以上
