Double post! Though I'm doing this because I expect that the first post may be edited in the future as more games are mapped.
Currently, most of the major games on the list have already been done long before I made up the list. The biggest games remaining include SMW2: Yoshi's Island (Peardian?), TMNT IV: Turtles In Time, and Super Castlevania IV (TerraEsperZ?). And some Disney/Capcom games, and of those The Magical Quest Starring Mickey Mouse is probably the most memorable.
(If you count the Mega Man X games as Mega Man games (even though many would consider them separate from the non-X classics), then Mega Man X & Mega Man X 2 are on the list, though they're probably on their way to completion by Geminiman anyway (who's also done some maps for Bonkers).)
I don't expect this to be finished as quickly as the NES Atlas, if ever at all. I'm just throwing it out there (glances in Will Mallia's direction)...
If you were wondering, earlier I had Mickey Mania, Mickey's Ultimate Challenge, Maui Mallard In Cold Shadow, Pinocchio, The Lion King, and Toy Story on the list for the "Disney Dizziness" chapter, but have been removed as they weren't made by Capcom. Some may have been published by Capcom in certain parts of the world but the games were not developed by them. Not that there were ever "rules" that the games in this chapter had to be Disney games specifically developed by Capcom (the original NES Game Atlas only had Duck Tales and Chip 'N Dale: Rescue Rangers, after all), but aside from The Lion King (already mapped by Grizzly) and Mickey Mania (looked good from what I remember, at least), the other games just aren't any good, in my opinion. I doubt anyone would even want to map them. They're certainly not worth mapping over so many other games available on the Super NES. I wouldn't miss them.
