Capcom is going all out for their throwback title Mega Man 9. Hironobu Takeshita, despite having quite the unfortunate spelling of last name in English, revealed in a talk with Gamasutra that the game is going beyond the call of duty and including several “features” from the NES era, such as bugs and sprite flicker. In a nice touch, Capcom has made some of these inclusions, like flicker, optional.
Something tells me that the developers making the 8-bit throwback might have some extra time on their hands. I just hope this level of commitment is present in every aspect of the game.
