Because of the Game Boy Color's limited color capabilities, the bike sprites overlay on top of the prerendered roadways nearly seamlessly and interact with them just as perfectly. The only thing that's really noticable is the fact that the road doesn't change perspective when you move to the far right or left of the track. Because this is Motocross , the developers did put in a freestyle mode, and this is the only place you'll be able to pull off some serious tricks. I'm not sure why the developer limited the tricks to only the freestyle mode instead of putting this option in the race as well, just for fun. But the freestyle mode is a definite plus, even if it's hard as heck to score points as high as the record holders that are documented on the cartridge.
Shame there's no battery save to keep the records intact.
But once figured out, the game actually plays smoothly. Unfortunately, the way the game has been made is also Championship Motocross's ultimate problem. Because of this limitation, all tracks look identical, even though they're all constructed differently. Worse yet, it takes as much as three minutes to complete a lap around these rendered courses, and when each race lasts five laps, the game tends to get a little long. Try as I might, I've never been able to catch up to an opponent who's two turns ahead of me, no matter how flawless a lap I pull.
