Well, after mapping the sequel to this game, JonLeung suggested that also do the original. So here I am, doing just that.
I must say, this game still holds pretty well, especially for a licensed game of the era. The controls are just a tiny bit worse than the sequel and there's less variety in terms of gameplay and stages, but I still kinda prefer this one for the (in my opinion) better graphics and better-looking stages. For the stage names, there are none mentioned in the manual so I went with those from the Nintendo Power issue that covered the game with the exception of one (that's a castle, not a cave) since those are the only names I found repeated on a few online FAQs.
I should note that contrary to the minigames from the sequel, I also added the reward for each basketball court since all three maps are otherwise identical. I realize I didn't mention the rewards in the sequel but that's because not only does the game not tell you what they are, but I never found out from playing the game, reading the manual or searching online. I wonder if that might even a been a dropped feature...
Anyway, here's what I've completed so far:
