[Update: It turns out that the enhanced maps and tilesets were made by Jon Leung of VGMaps back in April 2007. He wasn't properly credited for the use of his edits. Not cool, Flip Industries. Not cool at all.]
Kid Icarus will return this March in Uprising, the first new game in the series in over 20 years. Understandably, many may want to refresh their memories, while others may not have played the oiginal or the Game Boy sequel at all.
You have two ways to brush up. One, Nintendo will be releasing a 3D Classics version of the NES original that sports brand new, fairly detailed backgrounds. Two, you can check out the above fan-made Flash remake, Super Kid Icarus. I wouldn't call it a total conversion (some sprites obviously didn't get redrawn), but it's something fun for a rainy day.
A lot of you will probably wait for the 3D Classics release anyway, and that's fine. However, the 3D Classics version won't have a map editor! Unfortunately, developer Flip Industries is withholding the map editor until the game receives a total of 950 "likes" on Facebook and Google+, and it's currently about 300 "likes" shy of the goal. Why lock something so cool away like that?
