- 0.88u5: Added GP Rider (set 1, 317-0162) (Sega 1990) and clone GP Rider (set 2, 317-0163).

- 13th November 2004: Charles MacDonald - Dumped GP Rider FD1094 CPU. Haze: Seems to have a few(!) graphical issues though at the moment. The road seems to be drawn with a combination of sprites and bg layers. I think they must do some crazy rowscroll/select effect with the bg tilemap because it just looks wrong if you hook it up (priority is also 100% incorrect, road is over sprites if you draw the bg). The game has no road rom (odd considering its an xboard game).
