Somehow, I guess I am more qualified to hunt Pokémons than diamonds
. Missed more than a third in the Alien levels (not that I seeked them especially).
Btw regarding sprite vs background in secret areas, if memory serves right, in Turrican 3, in the golden armour zone, the Turrican sprite is visible and in 1-up secret areas of the junkyard level the sprite is invisible.
In mega Turrican, it is the opposite (well, there is no golden armour but still there is one one-up).
