The arcade game Space Harrier was originally released by Sega in 1985. It should come as no surprise that this PC-Engine conversion of Space Harrier shows various differences with the original and blazing fast arcade game. The most obvious difference is the checkerboard pattern that was replaced here by horizontal lines. Then sprites are far smaller than the arcade, but it was most certainly the optimal trade off to create a game that runs surprisingly close to arcade speed. Finally, Space Harrier was technically the first 4 Mbits Hucard game ever released, and is apparently the only Hucard game not compatible with the SuperGrafx system (there is however a mode switch at the back of the console to turn it back into PC-Engine mode).
