569 in original bd, the counter was only two-digit. so bd3 cave f
570 says 150 diamonds required, but you only had to collect 50.
571 also, gate opening is triggered by incrementing diamond
572 count and THEN checking if more required; so if required was
573 0, you had to collect 100. (also check crazy light 8 cave "1000")
