Was told yesterday that originally the coders of Hard Drivin' were lined up to do the Z80 versions and then Binary Design closed so the job went elsewhere. So the game may have ended up as a full 3D game like Hard Drivin'! Although seems difficult given the memory limitations.
Either way, this feels like a mid-rated budget game not a top tier arcade conversion. Feels like the impression of movement is being given by flashing and the games is very empty.
