Jaz: It's a bit easy, but Rainbow Islands is still a fun conversion. The scores are a bit high - mid to low eighties for them all would be about right for now.
Rich: You'd have trouble actually finding this game nowadays, which is a shame because it's still quite smart. It does show its age though - the flickery graphics are unacceptable this day and age and the ease of the game in "easy" mode doesn't help much either. I'd knock around 10% off each rating.
