In the SEGA Arcade/Genesis/Mega Drive game Flicky, why does knocking out a cat only sometimes yield a diamond?
You can see what I am talking about 20 seconds into this video:
Diamonds are worth various amounts of bonus points, and exactly what governs their value would be a second part to the question.
I've played the game for years, and I own the original arcade cabinet, but I've never been able to figure this out. The only guaranteed way would be to decompile and analyse the original Z80/68000 code.
Indeed, the behaviour might even be different across platforms.
Any thoughts or information appreciated.
