The size of the screen and the amount of shit that can happen on screen at once detracts you from a "true to arcade" conversion. The Amiga graphics were also converted from the arcade version and if looks are the judging bar, then the Amiga version looks BETTER than the CPC one.
Please explain how the lower one, specially running at less than 50FPS, looks better than the middle one.
Anyway, I think this CPC port is superb, but one thing is that and one thing is fanboyism
And the PC-Engine is NOT above the Amiga.
