Richard Leadbetter lied to us. Maybe. https://retrocdn.net/index.php?title=File:SSM_UK_36.pdf&page=77 The UK's Sega Saturn Magazine printed a load of special dates for Christmas NiGHTS. Let's debunk some: "25th December - Father Christmas!" - Nope. Not sure what this means but I didn't see anything. "1st January - Happy New Year!" - This is a correct - you get a different title screen and the kids have new outfits. "14th February - Valentine's Hearts" - Nope. Hearts do drop if it's midnight but the day doesn't matter (as long as you're playing the Winter/Christmas version) "1st April - April Fool" - This does happen - NiGHTS is replaced with Reala, and if you win, this becomes a permanent option. "31st October - Halloween" - Nope. Sadly. "31st December 2099 - Fluorescent snow!" - Nope. Someone's having a laugh... unless there are different rules for the PAL version (this is NTSC-U) As for the time of day affecting what falls. SSM's list is slightly wrong and incomplete, while ours is also wrong... except it's complicated because the background changes too, and that seems to be independent from the "snow setting". So expects required there. Here's what (I assume) is the full list of falling objects. Most of the time you get snow, but at certain times of day, you don't: 00:00: Hearts 09:00: Moons 12:00: Purple gems 15:00: Sweeties 18:00: Sparkles 21:00: Stars Yes it is very satisfying that I managed to line up the screenshots perfectly. p.s. I'm sure one of these games was meant to change for St. Patrick's Day. I can't remember which one though.
