Motocross Championship
From Sega Retro
There was a PC version built for internal development, not for sale. It let us put in graphics and test gameplay on development PCs without having to rely on the one working Sega 32X hardware prototype (we had two, each the size of a mini bar fridge, one was damaged in shipping from Japan).
By the way, there's more about the development in Retro Gamer magazine in an article about the Sega 32X, "Load 133" edition (September 2014).
