Thanks to vorpal86,
Felix The Cat is complete! I always thought that, as one of the later NES games (after the Super NES was already available), it was pretty decent. Though I'm not sure why as I never really spent a ton of time with the game...in any case, we have all the maps of it! Yay!
And now from the looks of it, with the exception of those games featured in the "4-Player Extra" special issue (Gauntlet II, Swords And Serpents), every NES game on a cover has now been mapped on VGMaps.com!
...Oh wait, there are two others remaining... Tetris and Dr. Mario. Hmm.
An idea for "mapping" Dr. Mario is, besides taking a screenshot of the empty bottle, maybe showing what each of the levels look like? I believe the arrangements are random, but it could be stated as such that they are so, and should be seen as possible levels that would at least show how many viruses (apparently plural is not "virii" anymore) there are?
Now that I think about it, someone did send me a map of the "well" in Tetris many years ago, and I thought it was too silly to put up. Whoever that was, I apologize for not accepting it then. Surely there's something more we can do with Tetris than just that, though...
So, yeah, not sure if anyone wants to map Dr. Mario and/or Tetris, but I guess it would be kind of a milestone if they were mapped, to be able to say we covered every NES game that was prominently on a cover of Nintendo Power! (Still hoping for some Gauntlet II and Swords And Serpents, just to be thorough.)
