I've played this on the Genesis (never got past 4-2) and the GBA remake (got through all levels). and I'm sure what I'm about to ask has been ask before. In Spring Yard Zone, in certain areas of the acts, I see "CPU" and "COPE" in flashing lights, as well as one place where it said "UP". Was there some secret meaning behind that?? I figured "UP" was obvious since you can jump to a higher platform.
